The lead story in this issue of Builders & Contractors looks at the future of concrete with Christchurch hosting the international fib Symposium this November.
We look at our national infrastructure with Civil Contractors New Zealand warning that future infrastructure projects might be scheduled too far in the future, and immediate stimulus is required to sustain the industry.
Also under the spotlight is the steel construction industry’s focus on the big picture, with a long-term perspective that isn’t just about reducing emissions today but ensuring our buildings and materials are part of an ongoing cycle that benefits future generations.
You’ll find pieces on the NAWIC and HIANZ awards, the latest building consent data and how to protect your business and employees during a recession.
There are also articles on the Government reconsidering insulation standards and how access to finance is a major barrier for the construction sector, plus much more.

Readers: Construction/building industry leaders and decision makers: government & trade organisations, site safe members, business owners and professionals in the industry.
Nationwide Distribution: Mailed directly to a carefully maintained list of decision makers and subscribers for 25 years.
Builders and Contractors, a national trade newspaper targeted directly at New Zealand's building and construction industry. For some time we were aware that, although the building and related trades were generally covered individually by some trade journals, there was no amalgamated news link for trades as a whole, especially on a nationwide basis.
This void has been successfully filled by Builders & Contractors. Distribution is by way of various outlets: PlaceMakers, Mitre 10, Builders Hardware, Site Safe Members, timber companies, hire companies, together with our database direct mail drop to architects, draughting professionals, consulting engineers, building consultants, designers and local Councils. By these means we aim to reach one of the most powerful buying groups in the industry.

While comfort and practicality are the most important considerations for tradies’ attire, a little attention to the way we dress can boost confidence and a sense of professionalism.
Above all, industry professionals must prioritise function over fashion, but achieving both is certainly possible. Your clothes need to withstand tough working conditions. Speaking of, our nation’s weather can be four seasons in one day, so layering and preparing for the conditions to turn is key.
Going for breathable fabrics such as cotton, polyester, and blends will wick away moisture, leaving you feeling fresher for longer. Protecting your skin by wearing sunscreen is another outdoor work essential. Along with drinking plenty of water, eating well, and maintaining good hygiene, you’ll be feeling fresh and clean right until the tools are down.
Every tradie’s wardrobe should include some staple items. You can’t go wrong with some quality work pants; durable and comfortable pants with reinforced knees and pockets are worth investing in. On t-shirts, go for blends that can handle sweat and dirt. Further, a warm and waterproof jacket or three goes without saying.
Safety and comfort should be your top priorities when choosing sturdy work boots. Practical headwear follows the same mindset. Beyond a beanie or cap that can protect your head from the sun or cold, protecting your head on site is no laughing matter. WorkSafe says that “Protective clothing must be a suitable size and fit. It must also be reasonably comfortable to wear and be compatible with any other PPE or clothing workers are required to wear or use.
“PPE should only be used as a last line of defence after all other reasonably practicable actions have been taken to eliminate or minimise risks. Risks must be managed firstly by elimination or, if this is not reasonably practicable, through minimisation.”
Remember, while looking good can boost confidence, safety and comfort should always come first.
Protective clothing must be a suitable size and fit. It must also be reasonably comfortable to wear and be compatible with any other PPE or clothing workers are required to wear or use.
On style, why not add a pop of colour with a bright t-shirt or accessory to add personality without compromising on practicality? You could even add patches or stickers to your workwear for a unique touch. If you wish, experiment more stealthily by layering different shades of the same colour for a stylish look. Any sort of forethought and cohesion to your look goes a long way, especially when trying to entice clients and managers.
There are a handful of dedicated workwear stores in New Zealand that offer a wide range of options specifically designed for tradespeople. Importantly, when shopping

for workwear, prioritise comfort, durability, and fit. It’s worth investing in quality pieces that will last.
Tradies might not think that their clothes matter, as their function matters above all. However, how we present ourselves can have profound impacts on how we think about ourselves, and tradie fashion is not exempt from this rule. Whether you’re battling the elements or meeting clients, dress with pride and confidence. A well-presented tradie is a respected tradie.
While Civil Contractors New Zealand has welcomed the clarity delivered in the Government’s future infrastructure funding plans, provided by Budget 2024, it warns that projects and work programmes may be too far in the future, and immediate stimulus is required to sustain the industry.
Civil Contractors New Zealand chief executive, Alan Pollard, says that while the Budget provided much-needed clarity about the future work programme, and the government should be congratulated for its focus on delivering infrastructure, urgency is needed to bring work and restore confidence in the market, so infrastructure constructors could be ready to go when projects, both large and small, come online.
“It has been hard for contractors to wait over the past few months,” Alan says.
“A significant gap in central and local government work has meant contractors have been holding on for more clarity on how, when and where the infrastructure work programme will be delivered.
“The 2024 Budget at least gives clarity, but we must work with urgency to resolve the current market downturn, so we aren’t laying off staff when we should be building capacity, so we can get back to work constructing and maintaining the vital transport, water and other infrastructure networks New Zealand relies on.”
Alan says contractors were resilient, but many companies were struggling and downsizing because of a lack of work, uncertainty around future projects and spiralling expenses caused by the rising costs of regulation and procurement.
The going was particularly tough in the Auckland region, which had seen a ‘perfect storm’ of projects deferred, cancelled, and rethought.
While the agreement with Watercare provided some welcome relief in that region, other regions, such as Canterbury, had considerable construction capacity and capability but very little forward work.
He says the delay from project announcements to construction was sometimes lengthy.
Government re-alignment and improvement of infrastructure investment planning and policy during this term of office was important, but urgent attention was needed to fill the immediate workflow gap so a strong and stable civil construction industry was ‘ready to go’ when projects hit the market.
It did not make sense to hold off and for businesses to scale down, at a time when infrastructure investment was sorely needed, he says.
“While the prospects for infrastructure investment under the coalition government look very positive in the medium to long term, work in the short term has dried up as clients (central and local government) cancel or defer projects.
“The largest proportion of business failures this year is in the construction sector, while other businesses are downsizing to ensure survival.
“That creates a significant risk for the delivery of the medium to long-term infrastructure programme, as scaling up again will require confidence to return to the industry.”
He says it is great to see funds for cyclone recovery. But longer-term adaptation works such as seawalls and stopbanks, to protect communities from severe weather events, needed specific attention.
While considerable cyclone recovery work was planned for in Hawke’s Bay and other impacted regions, much was still in the design phase rather than under construction, and a more coherent package of adaptation work was sorely needed.
“The latest Investment Statement from Treasury put our combined infrastructure gap at a whopping $210 billion.
“To make headway and create a thriving New Zealand for future generations, we need a lasting commitment from all political parties
to build and maintain the transport, water, energy, and communications infrastructure that’s desperately needed.”
Lack of workers and specific, targeted mental health support for under-pressure workers in construction were other key challenges faced by the industry, both during the gap in work and later, as industry scaled up to deliver on government’s vision for infrastructure, he says.
“It has been disappointing to see the lack of recognition for the skills of civil construction workers, who operate high-risk machinery at a large scale, over several decades.
“We need the education and immigration systems to better recognise the targeted skills that construction workers have and neednot just engineers and planners - but also skilled civil tradespeople who will construct the physical works we need.”

It might seem odd to suggest that social media is essential for the hard-hatted world of trades and contracting. Yet, the reality is that these platforms have become powerful tools for building businesses, connecting with clients, and showcasing expertise.
Social media isn’t just about cat videos and endless scrolling. It’s a platform for connecting with people, building trust, and ultimately growing your business. Gone are the days when word-of-mouth was the primary way to find a reliable tradesperson. Today, potential customers are turning to the Internet to research and find service providers. Social media offers a unique opportunity to tap into the digital world, allowing you to connect directly with your target audience.
By sharing your work on platforms like Instagram and Facebook, you’re not just showing off (though, let’s be honest, who doesn’t love a good before-and-after?). You’re demonstrating your skills, attention to detail, and commitment to customer satisfaction. People want to see the real you and your team. They want to know you’re passionate about your craft.
Instead of relying on traditional advertising, you can use platforms like Facebook and Instagram to showcase your work, share helpful plumbing tips, and interact with
potential clients. By sharing before-andafter photos of your projects, you’re demonstrating your skills and building trust. A well-placed video demonstrating how to unclog a drain can position you as a knowledgeable expert, attracting people who need your services.
While it might seem overwhelming, you don’t need to be a social media guru to reap the benefits.
Explore different social media platforms
Start by choosing one or two that align with your target audience. There are several different social media platforms available, each with its own strengths and weaknesses. If you’re targeting homeowners, Instagram might be a good choice for visually appealing content. For connecting with other businesses, LinkedIn could be more effective.
Consistency is key
Regular posting keeps your business top of mind. It doesn’t have to be daily;
WE ARE COMMITTED TO DELIVERING THE BEST INSURANCE SOLUTIONS FOR OUR CLIENTS NEEDS
Instead of relying on traditional advertising, you can use platforms like Facebook and Instagram to showcase your work, share helpful plumbing tips, and interact with potential clients.
even a couple of posts a week can make a difference. Mix it up with photos, videos, and informative content.
Focus on creating high-quality content
This could include photos and videos of your work, tips and advice, and behindthe-scenes glimpses into your business. People are more likely to engage with authentic content that they find interesting and helpful.
Engage with your followers
Respond to comments and messages, and participate in conversations. This will help
you build relationships with your followers and make them feel valued.
Leverage paid advertising
Social media platforms offer a variety of paid advertising options that can help you reach a wider audience and promote your business. This can be a great way to target specific demographics or interests.
So, give it a go. You might be surprised how much fun it can be and how many jobs it brings your way. After all, in a world where everyone is trying to stand out, a strong social media presence might just be your secret weapon.

The New Zealand government has recently introduced significant changes to the policies surrounding granny flats. These changes aim to address housing shortages, provide more affordable living options, and simplify the regulatory landscape. Understanding the nuances of these policy changes and their impact on tiny house regulations is crucial for homeowners, potential buyers, and industry stakeholders.
Granny flats, also known as accessory dwelling units (ADUs), have been a popular solution for accommodating extended family members or generating rental income. The new policy changes, which include increased size limits and simplified compliance requirements, are set to make these units even more attractive and feasible for homeowners.
Previously, granny flats were subject to strict size limitations and zoning regulations, which often made their construction complex and
486 2460 graham@southerntowers.co.nz Queenstown, Otago www.southerntowers.co.nz
costly. However, the new rules now allow these units to be up to 60 square meters in size, nearly double the previous limit of 30 square meters. This change provides homeowners with more flexibility in designing and utilising these spaces, making them more functional and comfortable.
One of the most significant changes is the reduction in regulatory hurdles. Under the new policy, constructing a granny flat will no longer require a full resource consent process. Instead, homeowners will only need to obtain an engineer’s report to ensure structural safety and compliance with building codes. This streamlining of the approval process is expected to reduce costs and waiting times, encouraging more homeowners to consider building granny flats on their properties.
These policy changes are not just about expanding living spaces; they also reflect a broader shift in how New Zealand addresses its housing crisis. By making it easier to build granny flats, the government aims to increase the overall housing supply, provide affordable housing options, and make better use of existing residential land.
The impact of these changes on the tiny house movement has been questioned by many. Tiny houses, typically defined as dwellings under 50 square meters, have gained popularity as an affordable and eco-friendly housing alternative. However, they have often faced regulatory challenges similar to those encountered by granny flats. With the new policy changes, communities are hoping tiny houses will eventually benefit from the same streamlined processes and size allowances.
The distinction between granny flats and tiny houses has often been a matter of terminology rather than substantive difference. Both types of dwellings serve similar purposes: providing affordable, efficient living spaces within a residential property.
The distinction between granny flats and tiny houses has often been a matter of terminology rather than substantive difference. Both types of dwellings serve similar purposes: providing affordable, efficient living spaces within a residential property.
One of the critical aspects of the policy changes is the recognition of the diverse needs and lifestyles of New Zealanders. By accommodating various types of small dwellings, the government acknowledges that one-size-fits-all housing solutions are inadequate. The flexibility in the new rules allows for a range of housing options, catering to different family structures, economic situations, and personal preferences.
The policy changes are expected to have a positive economic impact. By reducing the regulatory burden and associated costs, more homeowners are likely to invest in building granny flats or tiny houses.
However, it is essential to consider potential challenges and criticisms of the new policy. Some urban planners and community groups have raised concerns about the impact of increased density on neighbourhood character and infrastructure. While the streamlined approval process is beneficial for homeowners, it may lead to a surge in construction activity that local infrastructure may not be prepared to handle. Ensuring that these developments are accompanied by adequate infrastructure planning and investment will be crucial to maintaining the quality of life in residential areas.
While the new regulations make it easier to build granny flats, affordability remains
a key issue. Construction costs, land prices, and other expenses can still be prohibitive for many individuals and families. Therefore, the policy changes must be part of a broader strategy that includes financial support, affordable financing options, and other measures to make housing truly accessible to all New Zealanders.
The recent policy changes regarding granny flats represent a significant step towards addressing the housing crisis by increasing flexibility, reducing regulatory barriers, and promoting diverse living options. However, as the regulations are implemented, it will be essential to monitor their impact closely and address any emerging challenges, such as infrastructure strain and affordability issues. By doing so, New Zealand can ensure that these innovative housing solutions benefit all residents and contribute to a more sustainable and inclusive housing landscape.

Stats NZ reports that the number of homes consented to in the last year, which ended June 2024, has fallen to levels that were last seen five years ago.
That’s from construction and property statistics manager Michael Heslop, who added that “the number of both apartments and retirement village units consented in the year ended June 2024 is the lowest in the last nine years.”
According to Stats NZ, 33,627 new homes were consented to in the year ended June 2024, down 24 percent from the year ended June 2023.
Also, from Stats NZ, ready-mixed concrete statistics have emerged, indicating a downturn in construction activity.
The actual volume of ready-mixed concrete produced in the June 2024 quarter was 977,746 cubic metres, down nine percent from the June 2023 quarter.
In the year ended June 2024, 3.92 million cubic metres of ready-mixed concrete were produced, down 11 percent from the year ended June 2023.
In seasonally adjusted terms, the volume of ready-mixed concrete rose 0.7 percent in the June 2024 quarter, following a 3.8 percent fall in the March 2024 quarter.
Statistics NZ has been collecting ready-mixed concrete production data since the early 1990s as an indicator of construction and economic activity.
In the year ended June 2024, 14,916 standalone houses were consented, down 19 percent compared with the year ended June 2023. There were 18,711 multi-unit homes consented, down 28 percent over the same period. Multi-unit homes include townhouses, apartments, retirement village units, and flats.
2,178 new homes were consented to in New Zealand in June 2024, down 36 percent from June 2023. However, thanks to Matariki, there were only 18 working days in June 2024 compared with 21 in June 2023. Fewer working days in a month means less time for building consent authorities to issue consents for new homes.
All regions consented to fewer new homes in the year ended June 2024 compared with the year ended June 2023. But Michael Heslop said that while all regions experienced a
decrease in the number of homes consented, some of the main cities within those regions had a larger decrease than others.
Excluding Auckland, 4,023 homes were consented to in Christchurch city in June 2024, down 12 percent from 4,581 in the year ended June 2023.
Hamilton city saw 1,049 consents, down 29 percent from 1,471. Tauranga city saw
593 consents, down 36 percent from 929. Dunedin city saw 423 consents, down 9.4 percent from 467.
“Wellington city has seen a significant drop in the number of new homes consented, largely driven by a decrease in apartments,” Heslop said. Wellington city saw only 353 consents over this period, down 69 percent from 1,157 in June 2023.

The Silvercard Competent Operator Program is owned by the Hire Industry Association of New Zealand (HIANZ) and delivered by accredited independent trainer/assessor’s across the country.
HIANZ manages this program in an effort to support the Hire industry with the risks of ownership of Mobile Elevating Work Platforms (MEWPs). There is the assurance by the Hire Company that a person hiring one of their MEWPs is competent to use it if they are holding a Silvercard. This meets the Hire Company duty of care under the HSWA and it reduces the risk of the machine being damaged or used inappropriately under the stewardship of the competent operator.
If you own a MEWP, the above applies to you and in some cases may assist you with compliance requirements and insurance support.
As a business owner, you too have a duty under the HSWA to ensure all workers are trained in the tasks they perform. Understanding the quality of training a worker receives is the difficult one and where the Silvercard Program assists.
Silvercard is delivered to some of the highest standards in the vocational education sector. t's owned by the hire industry, making it the most closely connected program to the market, with access to the best and safest knowledge base. This ensures that learners receive the highest quality training possible. As a business, you can rest assured that a Silvercard Competent Operator has received the best training and assessment according to NZQA requirements, fully meeting the standards of regulations and legislation.
A real key point for businesses is that the Silvercard Program creates a safe, competent and productive worker.
This is what a business really needs. Safety in the workplace, competent operations of machinery on site and all done at a productive rate. These are the three biggest risks to a business covered: safety, quality and profitability.
That covers the Hire Industry, the biggest fleet owners of MEWPs and businesses.
But why train as a person/worker?
You, the worker need training for the exact same reason above, to ensure you are safe and don't get injured at work, ensuring you get home at the end of the workday, tired, but
As a business you can be rest assured a Silvercard Competent Operator has had the best training and assessment to NZQA requirements, meeting the requirements of regulations and legislation.
in one piece. That you are the best worker in the business, consistently delivering work that meets or exceeds the company's standards. I'm not saying you will get a pay rise for doing the Silvercard program, but it does contribute to those decisions. An employer will always consider a safe, competent and productive worker to be more valuable than one that isn't.
In summary, training increases everything we desire from work, whether you are the industry association, a MEWP owner, a business or a worker, we all want a safe, competent and productive worker and workplace.

Excitement is growing as New Zealand prepares to host the globally recognised fib Symposium for the first time, from 1113 November 2024, at Te Pae Christchurch Convention Centre.
Presented by Concrete NZ’s Learned Society, this prestigious event brings global experts together to share cutting-edge research and advanced practices in structural concrete. It is a unique opportunity for local professionals to engage with world leaders in the field, exchange ideas, and showcase New Zealand’s advancements on an international stage, fostering growth and innovation across the industry.
The fib Symposium is an annual event focused on cement and concrete that provides a forum to present and discuss state-of-the-art practice, recent progress and research, standards and guidelines, and future perspectives relating to durability, sustainability, and resiliency in structural and civil engineering.
What is fib?
The fib (Fédération Internationale du Béton/ International Federation for Structural Concrete) is a not-for-profit association formed by 42 national member groups and approximately 2500 corporate and individual members in more than 100 countries.
Its mission is to develop at an international level the study of scientific and practical matters capable of advancing the technical, economic, aesthetic and environmental performance of concrete construction. The knowledge developed and shared by the fib (bulletins, events, workshops, courses, etc) is entirely the result of the volunteer work provided by its members.
The organisation was formed in 1998 by the merger of the Euro-International Committee for Concrete (the CEB) and the International Federation for Pre-stressing (the FIP).
Concrete NZ’s Learned Society is a long-time National Member of fib.
The fib Symposium format features a diverse range of sessions to engage participants. Oral presentations will deliver traditional structured talks from experts, covering a broad range of research developments and project profiles.
Special sessions are themed discussions offering in-depth exploration of specific topics, while posters will provide visual displays, presented in designated areas, where attendees can engage with the authors.
As a new initiative, monitor presentations will provide a dynamic platform for presenting live, or through pre-recorded videos to allow for on-demand viewing. This multi-faceted approach ensures a comprehensive exchange of knowledge and ideas across various formats.

Providing a range of durable scaffold safety signs.
BCITO has launched a ‘Hire Boldly’ campaign aimed at employers in the building and construction trades, to help boost the number of women entering the industry.
The number of women in BCITO apprenticeships has grown from less than one percent in 2015; however, women still make up just over six percent of apprentices.
BCITO’s goal is to raise this figure to ten percent by December 2025 by focusing on addressing ongoing misperceptions about women’s ability to take on physical jobs.
Reaching this goal will clearly signal the industry is moving forward and considering people based on skills and ability for the role, not gender. In the painting industry, where 24 percent of BCITO apprentices are female, it is no longer unusual to see a woman at the business end of a spray gun, brush, or roller.
BCITO director Greg Durkin says, “Despite the recent slowdown in resource consents and the pipeline of work for New Zealand’s building industry, it’s vital to ensure we have healthy numbers of new people entering the construction industry and building skills for the future.
“Encouraging more women into the workforce is not only a matter of equality but
a strategic move to strengthen our industry’s resilience. Employers play a critical role in shaping the future of construction.”
In a 2021 report for the Women in Trades Collective, part of the industry initiative Trade Careers, almost half of the employer survey respondents (48 percent) agreed that hiring and supporting women tradespeople was a challenge because it would be hard to accommodate pregnant women in the workplace.
Forty-six percent also said they would find it difficult to hire women because the workplace can be physically challenging.
Women looking for work cited receiving questions from potential employers such as “you realise there is dirt involved in this job?”, or the outright statement “we’re looking for a male”.
“When we have examples such as the BuildHERS project in Whenuapai, a fourbedroom home project-managed and built entirely by a female crew, they demonstrate how outdated or misinformed these perceptions are. Women can do anything their male colleagues can do, and that’s what we hope to educate more employers about, to help the whole sector reach a goal of 30 percent female representation by 2040,” Greg says.
Employing more women in construction brings numerous benefits. By encouraging
more women to join the workforce, employers can tap into a broader talent pool.
A diverse workforce also brings varied perspectives, leading to innovative solutions and improved problem-solving. Women can offer new ideas and approaches that benefit the entire industry.
Companies known for their commitment to diversity and inclusion often enjoy a better reputation, which can attract top talent and improve relationships with clients and partners. Meanwhile, more inclusive workplaces also tend to have higher employee satisfaction and retention rates.
Kevin Paul Painters and Decorators co-owner, Maria Williams, says “The women and the men bounce off each other in ways that enhance the job. It’s been fabulous for us. In fact, we’ve become quite successful through it.”
How employers can make a difference
Review hiring practices: Ensure that job advertisements and recruitment processes are inclusive and free from gender bias. Consider implementing blind recruitment practices to focus on skills and experience.
Create supportive work environments: Develop policies and practices that support work-life balance and provide a safe and respectful workplace for all employees. Consider flexible working arrangements and mentorship programmes.
Promote training and development: Encourage and support female employees to pursue training and career development opportunities. This not only benefits the individual but also strengthens the workforce’s overall skill set.
Lead by example: Senior leaders and managers should actively promote diversity and inclusion within their teams. This includes addressing any unconscious biases and championing the benefits of a diverse workforce.

The news that building costs have mostly stabilised will please the industry.
According to the most recent August QV CostBuilder quarterly update, the average building cost per square meter for residential projects has increased by 0.3precent this quarter.
The rate of increase recorded in the February and May quarters is the same.
This discovery provides developers and builders with greater pricing certainty than at any other time since the start of the COVID-19 pandemic.
The construction industry was unpredictable due to the coronavirus, but this study shows that things have partially normalised.
“This is good news for anyone looking to build right now, as it will give them more confidence that the estimated cost of a project will indeed be in the same ballpark,” QV CostBuilder spokesperson Simon Petersen says.
“What we’re continuing to see is building cost inflation returning to much more ‘normal’ levels,” Petersen adds.
“However, there is still an abundance of economic and geo-political uncertainty that
has the potential to impact construction costs moving forward.
“This includes the possible escalation of conflicts in the Middle East and Ukraine, which could affect global supply chains.”
According to Petersen, this quarter’s average building cost per square meter for non-residential structures also increased by 0.2 percent.
This signifies a minor decline in the quarterly growth rate, which was 0.4 per cent in May and 0.3 per cent in February, respectively.
The two most significant elemental price increases were related to inside doors and sanitary plumbing.
“On average, each trade rate also increased by 0.2 per cent this quarter, with hardware and demolition up 2.9 per cent and 1.4 per cent, respectively,” a recent QV release reads.
“In contrast, the cost of steel framing reduced by 5.7 per cent, and suspended ceiling costs dropped by 4.5 per cent due to a reduction in suspended ceiling framing and panel rates.”

Increasing confidence in the ability to access finance for housing and major infrastructure like schools and hospitals is critical to boosting New Zealand’s productivity and lifting the building and construction sector out of its slump.
Over 1,000 homeowners and 300 builders took part in the annual State of the Sector survey, which asked respondents about their building experience, thoughts on the economy, critical issues facing the sector, and overall sentiment towards the year ahead.
Access to finance was flagged by 83 percent of respondents as the biggest challenge for building and construction in the current environment.
This is the second year it has ranked among the top three issues. It was followed closely by lack of consumer demand (75 percent) and rising construction costs (74 percent).
Chief executive officer of Master Builders, Ankit Sharma, says there’s no denying the current economic conditions have resulted in a slowdown.
“Confidence is the key to our recovery. We need businesses and clients to have the confidence that they can access money for projects, because it sends the signal that the economy is going to recover, and that it’s worth committing to the building process,” Ankit says.
“Government has released a series of policies to address the housing shortage and the perennial issue of affordability, which will help in time.
“However, the highly conservative approach taken by the banking sector is a major barrier, especially given we can see the relief that an ease in interest rates will bring.”
Despite the challenging environment, the State of the Sector survey revealed rich insights about those who have recently gone through the build process.
The overwhelming majority reflected that their experience had been “smooth,” “exciting,” and “excellent.”
The two largest concerns heading into the build process were how price escalations would be managed (48 percent) and project delays (18 percent).
“It’s incredibly encouraging to see that most homeowners report positive building experiences,” Ankit says.
“We know that many builders are very good at developing strong and positive relationships with their clients. Communication and transparency are critical, and having honest and open conversations about the risks and budget contingencies can help ease concerns and further encourage confidence.”
The State of the Sector survey also asked consumers about what information they’d sought from their builders at the

outset of their build. Around 90 percent of those conversations were in relation to building guarantees.
“Given the recent industry challenges and failures, our guarantee has proven critical in protecting homeowners and their investments. They are also a critical part of the equation for lenders, who are looking to protect their investment.”
The State of the Sector also illuminates the incredibly challenging and competitive operating environment, which has resulted in companies contracting for a wider range of work, seeking efficiencies in their businesses, and seeking ways to better market their services.
This year’s results show businesses are working hard to adapt to the changing market conditions. Some 76 percent of the sector said as a result of market changes, they have been forced to cut overheads, with more than 50 percent of these businesses making the tough decision to include staffing numbers in these reductions.
Just under half (43 percent) have looked to new markets to build out their pipeline of work, and more than 50 percent put a concerted effort into increasing their market presence through advertising and sales.
“We recognise this is a challenging economic climate and a lot of our members will be feeling the squeeze. Tough times, build tough businesses and the results show the sector is adapting, finding efficiencies and diversifying their business models.
“It highlights we have matured as a sector, and with the right mechanisms and support we can become even more resilient,” he says.
There are also green shoots of optimism appearing. Nearly half (46 percent) think overall economic conditions are likely to improve within the next 12 months, even if only 38 percent think it will flow into improvements for building and construction.
“Ongoing support for the sector is crucial. We have been open and honest with the government about wanting to work with them to find innovative solutions, and we must keep developing strategies to sustain the sector during tough times.
“Whilst winter may be here, we believe summer is coming, and it’s fuelled by a strong demand for housing and infrastructure.”
In July, Master Builders unveiled its sectorleading ‘Good Contracting Guidelines and Principles’ resources at Parliament. These resources ensure that risk is allocated appropriately at the planning stage, especially when a contractor is initially involved in pre-construction work.
“Through this initiative, we can improve productivity and foster more collaborative relationships between client and contractors from the start of the process.
“We were delighted the Minister for Building and Construction, Chris Penk was able to attend, and for his endorsement of the guidelines and principles – specifically with how they could potentially be applied to many government priorities, including some procurement practices.
“It is also imperative that the Government get back to building. The sector, across commercial and residential need more certainty in the pipeline of work.
“Master Builders will continue to look for solutions, and advocate for change on behalf of the sector. The results from this year’s State of the Sector shows the resilience of our people and companies.
“It also shows that they are doing a good job – making the build process a positive one for clients and homeowners.
“New Zealand has a shortage of quality housing and critical infrastructure including schools and hospitals. We can address this if we keep pushing forward with construction projects,’ Ankit says.

Cachet Group, a commercial interior design and construction firm, set itself the ambitious challenge of diverting at least 95 percent of waste from New Zealand’s landfills on a retail bank project in Westfield’s St Lukes Mall, Auckland.
Surprised and buoyed by their result in successfully diverting 20.8m3 from landfill—99 percent of waste from the site— Cachet is motivated to normalise this way of working for the industry.
Cachet director Greg Parsonson says when considering that 40-50 percent of New Zealand’s total landfill waste can be attributed to construction and demolition waste, the sector’s opportunity to materially impact the country’s sustainability efforts is huge.
“We set out to push boundaries on this project with the elusive ‘zero- waste’ goal in mind. It wasn’t easy because the industry norms supporting green construction simply haven’t been well-established yet, but we are incredibly proud of what we have achieved working together with the support of dedicated partners and contractors.
“While we were close to achieving a true zero waste outcome on this project, the reality is that there is no commercially viable way to rehome the remaining small percentage of waste from the site in New Zealand.
The unrecyclable material? Dust, cable ties and smaller hard plastics.
“We even looked at creative solutions for diverting the dust, such as commissioning a local artist to craft with it, but this wasn’t practical,” Greg says.
Dr Terri-Ann Berry from the Environmental Innovation Centre says, “New Zealand unfortunately doesn’t yet have the infrastructure to achieve zero waste on construction sites.
“Some materials just don’t have a suitable recycling option available while others, although theoretically recyclable, are very difficult to separate in a way that is clean enough for recycling.”
She explains that commercial drivers, such as the cost of labour in construction, means waste management needs to be practical and efficient to be viable.
She also points out that not all reuse or recycling options are of the same quality.
“Ideally, you would want to recycle waste into the same product or something else of high quality, but often downcycling is the only available option.
“There is still a lot of innovation required in this field, which has to be driven by real-life pilot projects, with willing industry leaders like Cachet testing better solutions.”
Greg agrees, adding that, “Another telling sign that we are in the early stages of adopting green construction practices as an industry, is the absence of an official programme or accreditation that can verify and validate it.
“It is our hope that as projects like the one we have just completed become more common, enablers to better waste management will strengthen and, together

with increased commercial viability, will support an industry-wide shift towards better waste minimisation practices.”
Diverting 99 percent of waste in this recent project resulted in some key differences to a typical contemporary site waste management plan, and Josh Stewart, Cachet’s senior project manager, explains the biggest difference was in the project’s procurement processes and a significant uplift in site morale.
“Identifying and verifying contractors and materials, and managing the site in a way that could support our waste elimination goals was challenging because in many cases this criteria is new yet growing for the industry,” Josh says.
“Once the project was underway, site management was required to monitor the busy nature of construction through careful and continuous waste observation.
This included monitoring even the smallest details, like ensuring contractors had reusable rather than disposable coffee cups and banning single-use and non-recyclable food packaging on site.
Sustainable waste management company Junk Run was commissioned to remove and divert recyclable waste from the site, and report on the results of the waste diversion efforts.
Greg Parsonson says Cachet is about to take the learnings and confidence gained from this project and do it all again with a new office fit-out for MYOB in an Auckland-based six-green-star building. It is already working on the workplace design for Spark New Zealand’s Auckland HQ.
“We are committed to pushing boundaries in pursuit of achieving zero-waste, and it’s fantastic to see demand and expertise growing across the sector with more project partners keen to be part of the journey.
“It’s through working together and growing demand that we have the best opportunity to achieve outcomes better for our environment and our communities.
“It is my goal that one day we will be able to report 100 percent of waste has been diverted from landfills on our construction projects.”

Construction technology business Payapps recently published a research report on its website about navigating the challenges and opportunities of quantity surveyors and contract administrators in New Zealand and Australia.
The 52-page report highlights the important roles both quantity surveyors and contract administrators play in the construction industry. It aims to understand the dynamics of job satisfaction, productivity, financial management, effectiveness, collaboration dynamics, and technology adoption.
Some of the key findings from the report’s survey showed that the majority of respondents reported feeling very satisfied with their jobs, which they put down to the significance of their work and their level of professional independence. Key challenges consisted of the demands of a heavy workload, the intricacy of projects, and the need for ongoing upskilling in order to stay up with the industry’s developments.
Although QS and CA professionals are skilled in handling their main responsibilities, there is a great deal of room for increased productivity. The underutilisation of technology, insufficient workflow procedures, and administrative overload have been identified as major obstacles to productivity.
Project success is closely correlated with the success of QS and CA professionals’ financial management skills. The survey has found a relationship between the probability of project completion within budget and schedule restrictions and the strictness of cost control techniques.
Crucial indicators of success include strong cooperation and communication between project teams and external stakeholders. According to the report, even with solid
foundations already in place, improving these elements can improve project outcomes and increase stakeholder satisfaction.
The idea that digital tools and technology have the power to completely transform the functions of QS and CA is widely acknowledged. The workforce hasn’t entirely embraced digital workflows and data-driven decision-making, though the adoption rates vary.
Following the survey’s key findings, the Payapps report provides recommendations for the identified challenges to foster industry growth.
According to the report, establishments and businesses should prioritise and support opportunities for ongoing education, with an emphasis on new developments in project management, soft skills development, and emerging technologies.
Businesses should make an intentional effort to acquire and use cutting-edge digital tools
and platforms that improve data analysis skills, expedite workflows and foster improved teamwork.
To find inefficiencies and implement best practices that lessen administrative costs and free up QS and CA experts to work on high-value tasks, a rigorous examination of current procedures is needed.
It is important to create initiatives that promote improved communication and collaboration between stakeholders and project teams, using technology to enable smooth information sharing.
Project outcomes can be made more consistent and predictable by creating and implementing standards for technology use, project documentation, and financial management.
By adopting Payapp’s report recommendations, businesses can advance their productivity and project success,

A study commissioned by the New Zealand Infrastructure Commission, Te Waihanga, has found that changing the way New Zealand charges for some of its key network infrastructure services could ensure they are used more efficiently, guide better investment, and, in certain cases, avoid costly capital projects.
Te Waihanga general manager of strategy, Geoff Cooper says, “We use a number of funding mechanisms to raise most of the money we need to pay for our network infrastructure services - the water we drink, the roads we use to get to work, the electricity to light our homes.
“Sometimes funding approaches are obvious and connected to how much we use, like monthly electricity bills and mobile phone bills. Other times they are far less visible, like fuel excise that’s included in retail petrol prices or rates and taxes, which pay for many of the infrastructure services that we depend on.
“We commissioned PwC to look at pricing in our four main network infrastructure sectors - land transport, water, energy and telecommunications sectors. We wanted to understand three key things: First, what does good network pricing look like?
“Second, how do different sectors perform against best-practice principles? Third, because equity and affordability concerns are so important for New Zealanders, we wanted to know how households are affected when we change prices,” Geoff says.
A key finding from the study is that the telecommunications and energy sectors perform well against best-practice pricing principles, while the land transport and water sectors perform less well.
“Energy and telecommunications rely more on direct-user charges and perform far better against best-practice pricing principles as a result. Like shopping in a supermarket, customers can pick and choose how much they consume and pay accordingly.
“These are also the sectors that have kept project investment levels in check with population growth over the last three decades,” he says.
“Sectors with better pricing have an easier time raising the right amount of money for high-quality projects, can better identify the highest-value areas for investment and are strongly incentivised to maintain their assets.
“These networks also tend to operate more efficiently, as users have good information and incentives to use infrastructure most efficiently.
“While land transport and water currently do not perform as well, we see significant potential for improvement. For example, more councils are introducing volumetric water charges, which are proven to reduce excess water consumption and improve leak detection.
“Other examples include central and local government working together to progress congestion pricing, which will take the edge off urban traffic congestion and many local authorities are improving the way they price development contributions, which can see us building in areas that have lower infrastructure costs,” Geoff says.
Dan Marshall, a Partner at PwC, says “Well-performing sectors, such as energy and telecommunications, have system settings that were designed to promote competition and incentivise efficient investment in services.
“Pricing is a powerful tool in sending signals to suppliers about where and how they should invest, as well as to users about when, where, and how they can access infrastructure services.”
Geoff Cooper says the study identifies key opportunities for each sector. “Whether it’s finding ways to improve price signals in land transport, investing in water metering, managing technology risks in telecommunications, or incentivising efficiency in energy, there are lessons that can help strengthen our infrastructure networks.
“The study makes clear that for many of the problems we face, it is not how much we are paying for infrastructure, but how we are paying for it.”
Key findings from the study:
The research outlines three best practice goals for how infrastructure networks should be priced:
• Pricing should guide infrastructure investment to ensure that we can provide and maintain the infrastructure we need. This is the most important to get right as network infrastructure is long-lived and can impact our future choices
• Pricing should send signals to users about when, where, and how they should use infrastructure networks to maximise the overall benefits of those networks. This is the second most important goal as service levels and investment needs are highly influenced by user behaviour
• Pricing should be used to share benefits of providing networks widely through society. This should be addressed through adjustments to pricing once the first two goals are achieved.
Other findings include:
• The research includes a desktop-based assessment of New Zealand’s four main network infrastructure sectors against best practice goals. This is a broad assessment of overall pricing systems and practices, supported by a set of quantitative case studies, rather than a detailed analysis of prices within each sector
• The key finding of this assessment is that infrastructure pricing is better aligned with best practice goals in electricity and telecommunications, and less well aligned in land transport and water
• Sectors with better pricing practices have an easier time raising the right amount of money to maintain and improve their assets and identifying the highest-value areas for investment. These networks also tend to operate more efficiently
• As a result, improving pricing of network infrastructure can help to improve infrastructure investment. It can do this by increasing the amount of money available for investment, where there is demand for investment, and also by reducing or deferring the need to invest
• The research identifies opportunities to improve pricing performance in all sectors. For example, transport congestion charging to reduce urban road congestion, implementing water metering to support water conservation and leak detection, managing technology change in telecommunications, and incentivising energy efficiency and decarbonisation
• The research considers the equity implications of changes to infrastructure prices, which can be a barrier to moving towards better pricing practices. How we charge for infrastructure can affect the distribution of costs between highincome and low-income households. The research quantifies the impacts of increasing different types of charges on different types of households
• Lastly, the research identifies opportunities to collect and analyse existing data to monitor the effectiveness of network pricing.
“Low-carbon” concrete is gaining traction in today’s construction sector. Defined against independent sustainability assessment organisation’s baseline data, this eco-friendly mix boasts a significantly lower Global Warming Potential compared to traditional Ordinary Portland Cement mixes.
An important part of Concrete NZ’s engagement and advocacy work is communicating that industry has a clear and achievable path to become net zero carbon by delivering low-carbon concrete, and explaining exactly what makes this type of new concrete “low-carbon”.
2050 pathway to decarbonise
New Zealand’s concrete industry has the ambition to reduce emissions, and in late 2023 unveiled A Net-Zero Carbon Concrete Industry for Aotearoa New Zealand: Roadmap to 2050.
This plan reflects a commitment to the Climate Change Response (Zero Carbon) Amendment Act 2019 and its aim to meet the greenhouse gas (GHG) reduction targets under the Paris Agreement.
Put simply, the industry aims to achieve netzero emissions by 2050, with the Roadmap providing a realistic pathway for all concrete stakeholders.
The chart below shows the actions (‘strategies’ or ‘levers’) that will be used to achieve net-zero GHG emissions from cement and concrete in New Zealand by 2050.
In addition to clinker factor reduction, replacing some Ordinary Portland Cement with Supplementary Cementitious Materials (SCMs), embracing carbon capture technologies, improving efficiency in design and construction, and accounting for carbon uptake are expected to make the biggest differences. Industry also anticipates further small savings as the electricity grid continues to decarbonise.
Collectively, these strategies contribute to enabling low-carbon concrete. But how exactly do you measure, or rather specify, low-carbon concrete?
The term low-carbon concrete refers to concrete mixes with a lower Global Warming Potential (GWP-T) than a default Ordinary Portland Cement (OPC) mix of the corresponding strength class, as defined, for example, by the Infrastructure Sustainability Council (ISC) or the Australian National Life Cycle Inventory Database (AusLCI) baseline data.
This definition is evolving as the industry progresses in its decarbonisation efforts.
An initial understanding of the GWP of available concretes can be obtained by evaluating third-party verified Environmental Product Declarations (EPDs), although they do have limitations.
The term low-carbon concrete refers to concrete mixes with a lower Global Warming Potential (GWP-T) than a default Ordinary Portland Cement (OPC) mix of the corresponding strength class, as defined.
Various methods exist to reduce the GWP of a concrete mix. However, when specifying low-carbon concrete for a construction project, it’s crucial to consistently denote a performance-oriented requirement based on
the targeted reduction of GWP compared to a New Zealand concrete baseline (typically from the ISC or AusLCI).
This approach allows ready-mixed concrete suppliers to use the most appropriate mechanisms, such as SCMs, to achieve the end product. Other considerations include:
• Raw Material Production and Transport: Emissions from all ready-mixed concrete production activities, including raw material production and transport, are considered
• Cement Source: The specific cement source and associated up-front carbon are included
• Geographical Constraints: Locally available aggregates can affect cement demand and should be taken into account.
Lifecycle assessment (LCA)
LCA data is organised according to several modules, which are illustrated in the following diagram:
• Modules A1-A3: Raw materials extraction & processing, transport to concrete plant, manufacturing of concrete.
The table below provides baseline
GWP in kilogram CO2 equivalents per cubic metre of concrete for a range of common strength ratings:
Specifying a lower embodied carbon 25 MPa concrete may simply involve stating a 30 percent reduction in GWP from the ISC embodied carbon baseline of 313 kg CO2e/ m3, resulting in 219 kg CO2e/m3.
It’s recommended to liaise with the readymixed concrete supplier to review how low-carbon mixes can be optimised while meeting performance criteria.
Module B1: Use of a concrete building
Exposed surfaces of hardened concrete begin absorbing atmospheric carbon dioxide immediately, a natural process called “carbon uptake”. Over time, at least 15 percent of the original emissions from cement production are taken up in concrete.
The Intergovernmental Panel on Climate Change (IPCC) formally recognised carbon uptake, or “recarbonation”, as a CO2 removal mechanism in its 6th Assessment Report (AR6).
Module B6: Operational energy
Concrete’s thermal mass helps save on heating and cooling bills. Additional benefits of concrete include flood resilience, fire resistance, low vibration, acoustic separation, and a service life that can exceed 100 years.

Beyond its end of life, concrete in buildings can be:
• Reused: Building elements from demolished buildings can be incorporated into new buildings
• Recovered: Demolition concrete can be crushed and used as clean fill for land recontouring after quarrying or infrastructure projects
• Recycled: Research in New Zealand shows
that crushed demolition concrete can be recycled into new concrete.
Environmental product declarations (EPDS)
EPDs quantify the environmental impacts of building materials following an internationally standardised framework under EPD International. They are a type of LCA that involves third-party verification of calculation methods and input data published by recognised EPD operators like EPD Australasia.
Many New Zealand cement and concrete companies have EPDs for their products, generally published on EPD Australasia, which is searchable.
As some published EPDs can be out-ofdate, a more agile approach is to produce third-party verified LCAs. Ready-mixed concrete suppliers should be able to provide customers with the latest LCA information for their products.
Advancing wider understanding
In short, Concrete NZ’s message is that low-carbon concrete refers to mixes with a GWP lower than standard OPC mixes, as defined by independent sustainability assessment organisations.
Concrete NZ also recommends that specifiers of low-carbon concrete engage with local ready-mixed concrete suppliers early in project planning to determine material availability and logistical capability.

The new range of MAX® TwinTier™ Rebar-Tiers can tie rebar faster and with more power than ever before! These are the sixth generation tools from MAX® Japan and by far the best!
Three new generation MAX® Rebar-Tiers make up the TwinTier™ range. Introduced with 3 new design features to provide the greatest efficiency and highest level of safety for reinforcing ironworkers.
The TwinTier's "dual wire feeding mechanism" increases tying speed by reducing the time needed to twist and feed the wire, consequently reducing the cost, and shortening the time required for construction. The tool’s dual-wire wrap ensures each tie is reinforced for maximum hold.
The TwinTier's “wire pull back mechanism” firmly pulls the tie wire in to adjust the tie to the rebar’s size to maximize the strength of the tie. When forming a tie the tool makes a loop with the wire and then pulls the wire to tightly secure and lock the rebar in place.
The TwinTier's “wire bending mechanism” feeds a precise amount of wire to match the thickness of the rebar being tied and
cut down on the use of unnecessary wire. This bending mechanism consistently feeds, pulls back, twists and releases the perfect sized tie for the each application.
The TwinTier's quick load magazine makes changing wire spools a piece of cake, and its frontward position provides improved balance/ ergonomics, making flatwork easier.
This generation of the MAX® Rebar-Tiers produce ties that are approximately 50% shorter in height, allowing for thinner concrete pours. Also, the ends of each tie are positioned downward to increase safety. Additionally, wire spools now produce up to 240 ties (when tying D12 x D12 rebar).
• The RB441T Rebar Tier is designed to tie D10 x D10 up to D22 x D22 rebar
• The RB611T Rebar Tier is designed to tie D16 x D16 up to D29 x D32 rebar
• The RB401T-E Standup Rebar Tier is designed to tie D10 x D10 up to D19 x D19 rebar.
The TwinTier's quick load magazine makes changing wire spools a piece of cake, and its frontward position provides improved balance/ergonomics, making flatwork easier.
A low “battery power consumption” design allows the tool to produce 5000 ties per charge using a 5.0Ah, 14.4volt Lithium-ion battery, which recharges in just 60 minutes.
The tool’s six-step torque adjustment dial allows its user to adjust the strength of the tie based on the application. Steel, electrogalvanized and polyester (“poly”) coated wire are all available for use with
the MAX® TwinTier™. The MAX® TwinTier™ works at double the speed and produces double the number of ties from a single roll of wire than the previous model and far exceeds that of any of its competitors.
Overall, no matter the application, the MAX® TwinTier™ reduces the time it takes to complete a job, saves businesses money by cutting man hours needed for each project and increases the productivity of its workers. For more information visit the SIFCO website - www.sifco.co.nz
Wet weather is common in most parts of New Zealand, making the damage caused by rain to freshly placed concrete a major concern.
Symptoms
The symptoms depend on when rain arrives in the placing process. If the concrete has been floated and trowelled and is nearing setting, the damage may be limited to some surface marking.
If the rain arrives prior to trowelling, there is a real risk that the surface will start to dust later. The image with a finger shows a driveway where rain occurred during the finishing process, resulting in a dusty surface. Over time, the dusting surface was abraded in the wheel tracks, exposing the aggregate.
Why dusting occurs
The strength of concrete is directly related to the water/cement ratio. The higher the ratio
(i.e., the more water added), the weaker the concrete. When water, either from rain or the bleed water, is mixed into the surface during the finishing process, a very weak concrete layer is created.
Typically, this weak layer is 3-5 mm thick and the concrete below is usually sound. It is this weak surface layer that is the source of the dust which is created by surface abrasion.
What can be done to prevent it?
The simplest answer is to avoid placing concrete when there is a threat of rain. However, there are times when rain occurs despite the forecasts for good weather. In these instances, it pays to have a contingency plan. Under clause 7.1.3.2 of NZS 3109
Concrete Construction, the contractor has a responsibility to protect freshly cast concrete from the effects of rain.
For trowelled surfaces, one option is to lay polythene over the concrete surface as soon as the rain starts, and then wait for it to cease. When the rain has stopped the polythene should be rolled back from a small
area at a time and then finished. Use the moisture in the slab to finish and avoid the addition of any water to the surface during the finishing process.
This process is repeated until the entire slab has been finished. Do not pull the polythene off the entire surface in one go, as invariably, the surface will dry and become unfinishable. It is important to ensure that any water sitting on top of the polythene is not discharged onto the concrete. Start the curing process as soon as possible after finishing.
If a prolonged period of rain has occurred, better results can be achieved by using a “rotating plate compactor” to bring the fat up to the surface, then machine finish as normal. Pan floating may help if a rotating plate is not available.
For decorative concrete, particularly stamped concrete, potential practical contingency plans are limited as there is only a relatively small window of opportunity to conduct the stamping process.
The strength of concrete is directly related to the water/ cement ratio. The higher the ratio (i.e., the more water added), the weaker the concrete. When water, either from rain or the bleed water, is mixed into the surface during the finishing process, a very weak concrete layer is created.
As we all look for ways to build more sustainably, concrete has come under the microscope due to the high carbon cost associated with the production of cement. The reality is that every construction site requires concrete in one form or another because of its durability and strength.
While there is a lot of good work going on to find less carbon intensive ways of producing concrete, there are also ways of installing concrete that can reduce its environmental impact. One of these ways is re-usable formwork.
New Zealand builders have often used precast panels, or built their own shutters from plywood and timber. Both methods have their drawbacks. Plywood has a significant carbon cost in its production and shipping to New Zealand. It also uses hazardous phenolic resins in its manufacture and should be carefully disposed of, creating an even less desirable environmental impact as well as
delaying the construction process by creating more work. By contrast, overseas builders tend to hire reusable formwork shutters and pour their concrete in situ.
The thing the New Zealand market was missing was a lightweight, durable and re-usable formwork system. In 2020 FormShore introduced AluFix re-usable formwork panels with their unique polypropylene formface – Alkus. Alkus is easy to repair, fully recyclable and good for up to 1500 uses - a big improvement on plywood.
FormShore AluFix panels are easy to install by hand and builders are saving money on labour, transport, crane hire and materials by pouring their own structures. This significantly reduces the environmental impact of the formwork, while also avoiding unnecessary downtime and interruptions on site.
When the construction team has finished, the panels are returned to FormShore for cleaning and delivery to the next project.
FormShore AluFix not only saves money, but also helps with reducing the environmental impact of construction.
The case for in-situ concrete structures
Building sustainably also includes building structures which will stand the test of time. Building with in-situ concrete can overcome many of the issues by creating a robust structure with better connections between the walls, floors and structural elements.
In-situ construction can also provide greater flexibility to cope with changing site conditions, reduction of lead times and changes to programme. The transport logistics are often easier and the ability to pump concrete to the site, rather than use a crane, will save cost.
FormShore designs reusable formwork solutions for foundations, walls, retaining walls, columns, beams and suspended slabs. FormShore will provide a full design and engineering service so that builders can proceed with confidence that the formwork, shoreloading and associated bracing will take the concrete pressures imposed by the job. FormShore installation plans are clear and easy to follow. Formshore focuses on delivering crane-independent systems where practicable.

Reinforcing steel used in concrete structures is essential for the safety and resilience of those structures. Increasingly, reinforcing steel products are imported to supplement local manufacturing – this means it’s more important than ever to ensure products meet New Zealand standards.
For reinforcing steel, the AS/NZS 4671 standard outlines the minimum requirements for the product manufacturing and processing, and for product traceability. Engineers and procurers must understand the critical requirements that determine whether reinforcing product is compliant.
This can be difficult for end receivers to ascertain and demonstrate. And the added difficulty of ensuring traceability over the products journey through processing means many choose to use independent accredited certification of manufacturers and processors rather than validating and documenting compliance themselves.
This has become even easier and more secure with the introduction of digital certification and traceability systems, like ACRS Cloud.
Reinforced steel compliance
The New Zealand Building Code recognises the importance of using compliant safetycritical materials in structures. So both the BCNZ and NZS 3101 Concrete Structures standard reference the Reinforcing Standard AS/NZS 4671.
AS/NZS 4671 addresses several issues that impact the performance of reinforcing products within concrete structures that will contribute to the behaviour and quality of the material. The reinforcing standard also recognises that through the manufacture and supply of the product to the industry, there are multiple stages of processing and different levels of compliance testing required. The standard sets out requirements for the following, including the frequency and thresholds for testing, depending on the kind of reinforcing steel product:
• Chemical composition: a test certificate from manufacturer showing carbon equivalence as a ratio of carbon, phosphorus, sulphur and other allowing elements
• Mechanical properties: strength and ductility requirements for both individual batch and LTQ compliance – these include uniform elongation; tensile strength; yield strength. The standard outlines that a Factory Production Control (FPC) system and associated test program is required when products are processed.
• Geometric properties: checks on nominal diameters of cross-sectional; straightness of the bar
• Surface geometry: regular testing to maintain a minimum profile and projected area of the ribs, to ensure damage through the processing in minimised
• Different requirements for mesh: tests and inspections including assessing manufacturing methods, mechanical properties, surface geometry; production testing of the shear strength of the welds; the number of bars and the spacing
• Identification and certificates: surface marks identifying strength grade and ductility; marks identifying the steel
producer; labels/tags with processor/ manufacturer identification, types of products being supplied, heat/batch numbers, and the number mass or quantity of any bundle; documents with the bundle number. The products need to be identifiable to trace material back to the source.
To better understand the requirements of the standard and this topic, make sure to attend Dr. Andrew Wheeler’s presentation at the Concrete NZ Conference in Christchurch, on November 14.
Independent of the manufacturers, ACRS technical experts carry out annual audits at the manufacturing sites for all certificate holders.
Compliance checks for each bundle of reinforcing steel can be onerous, and staff taking receipt of a delivery might not fully understand the intricacies of compliance and what should be checked. So, to assist with this and improve efficiency on site, the New Zealand Building Code allows for industrybased schemes to assess manufacturers/ processors to the relevant standards to demonstrate compliance.
Schemes like Australasian Certification for Reinforcing and Structural Steels (ACRS) meet the requirements of being this type of industry body. Independent of the manufacturers, ACRS technical experts carry out annual audits at the manufacturing sites for all certificate holders.
These audits:
• Review the Factory Production Controls
• Observe steelmaking and post-processing operations
• Undertake random independent testing
• Ensure and test product traceability systems
• Review the ongoing submissions of the long-term test data.
The ACRS scheme is accredited by JASANZ and recognised internationally for its rigour and independence. It lists certified manufacturers/processors publicly with their associated scope of certification; including bar markings and examples of labels provided on bundles. And importantly, it demands and ensures certification and traceability through the steel’s journey, certifying both manufacturers and processors, and linking the two.
By specifying ACRS certification – and ensuring the corresponding product is supplied and delivered – the designer, builder and end user can have confidence that the steel producers has quality and manufacturing systems that have been verified and continue to provide products that are compliant to the standard.
Digital traceability
Traceability has been a requirement of the reinforcing standard for a while, but until
now it has been a paper-based system that can be cumbersome. With hard copies, it’s difficult to collate documentation and maintain links from products to the associated certificates. This process is further complicated as more processors are introduced into the supply chain. And the rise of falsified documentation has further damaged industry confidence in paper-based certification systems.
However, in recent years there has been an increase in the use of digital systems for tracing products and ensuring safety, especially in industries like cars and food. With recent issues in building safety in Australia, the UK and other jurisdictions, coupled with work being carried out under the UN Centre for Trade Facilitation and eBusiness concerning traceability and international trading, there has been a significant push to introduce digital product certification into the construction industry.
The need for traceability has been further emphasised by demand to supply environmental credentials with building products and the recognition that a material with an unknown source has unknown environmental credentials.
Consequently, we are seeing certification schemes such as ACRS move to a more digital platform to provide:
1 Confidence in the authenticity of certification certificates, and 2. To transition traceability systems from paper-based system to tried and tested digital systems.
Last year, ACRS introduced ACRS Cloud, the first digital certification system of its kind for steel in the region. It moves ACRS full certification and traceability from source to site to a digital system: ACRS Cloud gives steel buyers and users instant assurance over product certificates at the touch of a button, in a secure environment to provide confidence of products’ conformance to AS/ NZS Standards.
Users through the supply chain can get product piece of mind by checking the nature and authenticity of ACRS steel certificates in the new ACRS Cloud app – available free on Apple and Android.
The app put assurance in users’ hands wherever and whenever they need it, including bar and tag markings; where the product has come from; and its validity and its assurance credentials in the form of ACRS’ sector-leading independent certification.
The app further protects the market from product compliance issues: not just in poor product identification or deliberate misrepresentation, but by making it easier for users to check steel’s provenance at every stage.
Under the ACRS Cloud system, batchspecific tags with QR codes will be placed onto steel at steel producers, fabricators, and processors. In order to make product traceability more secure and accessible, ACRS certificates will carry QR codes which – when scanned at each point – will open validation
and vital product information in ACRS Cloud, instantly identifying the provenance of the product and its certification details against a single source of truth.
To confirm that the steel that’s delivered has been certified simply:
1. Download the app for free at steelcertification.com/cloud or in your app store
2. Scan the QR code on delivery papers or electronic certificate
3. View the certificate in full, including scope, origin, and key dates.
The app put assurance in users’ hands wherever and whenever they need it, including bar and tag markings; where the product has come from; and its validity and its assurance credentials in the form of ACRS’ sector-leading independent certification.
Ensuring compliance and traceability from mill to site
In summary, the New Zealand reinforcing standard outlines the requirements for suppliers to demonstrate compliance with the New Zealand Building Code. These
requirements include implementing factory production control systems along with the associated test programs to ensure that the chemical composition, mechanical properties, geometric and surface properties are all compliant.
These requirements to demonstrate compliance of product are not limited to the steel manufacturers, but apply to downstream steel processors. This is to ensure that compliance testing for mechanical properties and surface geometry is undertaken, and that traceability of product to the site is maintained. This means compliance during processing and traceability from manufacturer to processor to site, is needed.
When ordering – and importantly when receiving – the product, the receiver responsible for compliance sign-off needs to ensure that all testing and compliance checks have been conducted. But that can be challenging, especially with compliance at manufacturer and processor and traceability in between.
Luckily, the building code allows receivers to use accredited industry organisations to verify compliance. ACRS, accredited by JASANZ, is recognised as an international expert in the certification of reinforcing and steel products to the Australasian and New Zealand standards. ACRS provides confidence to specifiers and end users that certified manufacturers/processors have the systems in place to produce compliant products.
Traceability is a requirement of the standard to ensure that product is traceable at a
batch level, back to the point of manufacture. This traceability aspect is becoming an important compliance issue in construction as traceability and compliance are becoming new requirements coupled with ESG requirements.
ACRS’ digital system, ACRS Cloud, provides an easy, instant way to check this certification and traceability. But however they do it, designers, specifiers, and steel
receivers should specify safety-critical components such as reinforcing steels with recognised accredited third-party certification and, on delivery, should check this accreditation is demonstrated.
To learn more about meeting the standard for reinforcing steel, see Dr. Andrew Wheeler’s presentation at the Concrete NZ Conference in Christchurch, on November 14.

Buried lava foam from Taupō’s historic volcanic eruptions is paving the way for carbon reduction in concrete.
Stevenson is currently testing a new concrete substitute, Perlite, to reduce the carbon impact of their concrete.
Stevenson General Manager, Ben Hussey, explains that Perlite is a pozzolan, a natural volcanic resource that’s sourced locally from our Tokoroa quarry.
“Perlite can be used like other cement substitutes, up to 30 percent of the mix. It’s simple, reducing the amount of cement reduces the carbon footprint of the concrete,” says Ben.
“We recognised the untapped potential of the natural, local and low energy material to help fill a gap in the reduced-carbon concrete market.”
Cement manufacturing is a carbonintensive industry with high heat processes and energy requirements.
Perlite is an alternative to other concrete substitutes, like fly ash and slag, which are byproducts of high-carbon emitting coal burning and steelmaking processes sourced from overseas markets.
Demand for more sustainable concrete is a growing trend globally and will likely increase the demand and cost of these existing substitutes.
“We have this natural resource that only needs minimal drying and milling on the doorstep of our largest city that has decades of growth and development on the cards,” says Ben.
“It’s a no-brainer for Stevenson to develop this product as part of our carbon reduction journey.”
Natural pozzolans like perlite have been used extensively for centuries as a concrete substitute in Europe and America and have a proven track record in construction applications.
“While our Perlite Concrete will be a new product in the New Zealand market, pozzolan-substituted concrete is a tried and tested product used successfully overseas,” says Ben.
The first loads of perlite are on their way to Stevenson’s Ranui concrete plant and will be used as a substitute, starting at five percent, in concrete mixes.
Comprehensive testing and an independent product review will be completed in the next six months before Perlite Concrete is officially launched in New Zealand.
We have this natural resource that only needs minimal drying and milling on the doorstep of our largest city that has decades of growth and development on the cards.
Stevenson is working with a large residential developer and construction company in Auckland to be the first to use Perlite Concrete in their builds.
“These partnerships mean that Perlite Concrete can be included in design requirements and part of early plans before any orders are placed,” says Ben.
“Our key clients share the same carbon reduction goals as Stevenson and they’re excited about Perlite Concrete and the carbon reduction potential it offers.”
At Stevenson, we take pride in being an essential part of our community, delivering local products for local needs. By serving our community and creating value, we are more than a business – we are a cornerstone of New Zealand’s growth and prosperity.
Discover the future of sustainable construction with Perlite
With innovation and sustainability at our core, we proudly present our eco-friendly Perlite solution – the foundation for greener infrastructure today and tomorrow.
Sustainably different
Harvested from volcanic material, Perlite is a pozzolan that transforms when finely milled and mixed with water, engaging with calcium hydroxide to create new, eco-conscious compounds. Crafted to synergise with fly ash and slag, our Perlite concrete blend is estimated to have an impressively low carbon footprint of under 100kg per tonne.
Let us help you pave the way to a greener future with Stevenson’s Perlite – where innovation meets sustainability.
The answer depends on the severity of the problem and how quickly remedial action is taken.
For situations where the dusting problem is not severe and the problem is addressed early, the surface may be saved using a “dust proofer and surface hardener”. These are typically clear silicate-based solutions that are poured and broomed/squeegeed into the surface.
These solutions may not save a moderate to severe dusting surface, but as the cost is modest compared to other options, it may be worth trialling. If the surface has been left for a period of time, and wear has exposed the aggregate, this solution is no longer available as it will not hide the aggregate, so it is important to both acknowledge the problem and take action early.
Another remedial solution is to grind off the weak surface layer. This can create a rather attractive terrazzo effect. However, given that the floor was not intended to be ground, it would be unreasonable to expect an even distribution of the aggregate.
If a terrazzo appearance is not desired, then the weak surface layer can be removed by grinding, and a cementitious topping placed over the surface. These toppings can often be coloured and textured. In some instances, the only practical solution is to rip the concrete up and start again.

In July, RNZ reported that building and construction minister Chris Penk wants to roll back upgrades to insulation and glazing requirements introduced by the previous Labour government. The standards save a new home an estimated 40 percent on heating.
Per correspondence released to RNZ under the Official Information Act, government experts told Penk that the old insulation and glazing standards were “significantly lower” than other countries with similar climates and that upgrades had overwhelming public support when they were introduced in May 2023.
Penk was not persuaded by these experts, whose opinions contrast with those of some builders and developers in Tauranga, who told Penk that the H1 standard added $40,000 to $50,000 to the cost of a new home and caused overheating issues.
One building sector survey following the standards changes saw MBIE receive many complaints that homes were too warm and had to run air conditioning in winter. Further complaints said the new standards were not fully understood by architects or designers, that the upgrades had added $35,000 cost to a four-bedroom home, and that the changes were adding six to seven percent to building costs.
Penk sent a statement to RNZ saying that he had asked MBIE to “urgently investigate” the cost of insulation and glazing standard changes.
“Builders frequently raise concerns with me over the new requirements within clause H1 of the Building Code that they say are adding tens of thousands of dollars onto the cost of a home. There are also frequent reports of moisture and overheating issues that are leading to increased energy usage making the requirements counter-productive,” he told RNZ.
“In the middle of a housing crisis, while Kiwis are still living in cars and emergency accommodation such as motels, it is critical that we don’t create artificial barriers through well-intended but badly implemented policies.”
The Public Health Communication Centre said in a statement that “any rollback of our insulation standards will cost industry, energy savings, and our health, according to public health researchers.”
“There is a 20-year history of solid research in Aotearoa, New Zealand, showing that insulation not only improves energy
efficiency but also our health, with the benefits of insulation outweighing its costs,” says environmental health specialist Dr Lucy Telfar Barnard.
“Less insulation means more health sector costs and lower productivity. Even a top-up to existing insulation provides health benefits that make it worthwhile. The health and social benefits of insulation are nearly six times greater than the cost of the insulation,”
she says. “Industry has already invested in manufacturing and stock to meet the new code.”
The Passive House Institute New Zealand (PHINZ) opposed the rollback in a statement.
“The recent changes to the Acceptable solution in Building code clause H1 Energy Efficiency (H1/AS1) represented a positive step towards achieving the core objectives of the Building Act; people who use buildings
can do so safely and without endangering their health; and buildings have attributes that contribute appropriately to the health, physical independence, and wellbeing of the people who use them,” the press release reads.
“PHINZ acknowledges room for improvement in H1/AS1, but a rollback won’t solve the underlying issues.”
On revising H1/AS1, PHINZ says that
the industry must embrace international standards and ditch flawed tools. PHINZ advocates the use of building modelling to target maximum heating and cooling loads rather than mandating specific R-values for individual building elements.
Insulation Association of New Zealand (IAONZ) Executive Officer Richard Arkinstall says, “Insulation is a minor investment in new housing which generates significant
In the middle of a housing crisis, while Kiwis are still living in cars and emergency accommodation such as motels, it is critical that we don’t create artificial barriers through wellintended but badly implemented policies.
cost of living savings for occupants, saves the government healthcare costs, and improves economic productivity”.
“The new H1 insulation standards represent a positive first step towards a healthier, more energy-efficient New Zealand. By focusing on long-term benefits and choosing the right compliance pathway, we can ensure a sustainable future for the construction industry.
“Insulation represents approximately 1.2-1.4 percent of the total build cost of a new home but its impact is significant. Properly installed insulation offers a return on investment of $4 for every $1 spent through energy savings for families struggling with the cost of living, improved health, fewer sick days and reduced doctor visits. The small increase in initial build cost is worth it for higher quality housing that lasts for decades.”

Ensuring the load height of your truck is properly measured can be a fatal matter. One case from July 2021 saw a truck deflect into the path of an oncoming vehicle, tragically causing the car driver’s death. Despite being an experienced truck driver, the incident still occurred.
The judge noted that truck drivers do not have recognised industry standards or training to measure the heights of loads. Truck drivers must intimately understand the appropriate standards and regulations.
The Land Transport Rule: Vehicle Dimensions and Mass 2016 is designed to create a reasonable balance between efficient heavy motor vehicle fleet operations within the constraints imposed by the road network and the safe operation of heavy motor vehicles.
The Rule creates limits to the permitted dimensions and mass of vehicles, with particular emphasis on large combination vehicles. Vehicles first registered in New Zealand before 1 February 2017 that had complied with previous legislation still comply with dimension and mass limits imposed by said legislation.
All heavy vehicles must now meet the static roll threshold (SRT) requirements, though.
Vehicle stability can be greatly affected by how it’s loaded. The load needs to be arranged so that its mass and height are appropriate for the vehicle’s design and the type of load.
Before 2002, one in eleven log trucks rolled over each year in New Zealand. The Land Transport Rule 2016 means rollover among log trucks is now much less common.
A vehicle’s SRT measures the potential for that vehicle to roll over sideways. The lower your SRT, the less stable your vehicle. High SRT vehicles are less likely to roll over than low SRT vehicles, especially when going around sharp bends and in sudden emergency manoeuvres.
To improve stability, heavy vehicles with a gross vehicle mass (GVM) greater than certain specified limits must meet or exceed a minimum static roll threshold value.
Visit the Waka Kotahi NZ Transport Agency (NZTA) website for more information: https://www.nzta.govt.nz/
When a vehicle doesn’t meet or exceed the required stability limit, its stability can be improved by operating it with a reduced load mass and/or reduced load height. Another option is for the vehicle to be modified so it has adequate roll stiffness to operate safely at maximum carrying capacity.
There are some exceptions. If the vehicle or load exceeds the maximum weight and you believe you’re eligible for a permit, you can contact your nearest Waka Kotahi office.
In 2010, a new permit system was introduced for high-productivity motor vehicles (HPMV).
These carry a divisible or indivisible load and may be overlength and/or overweight but not overwidth or overheight.
Accurately measuring load heights involves using reliable tools such as height poles, laser measures, or height sensors. Truck drivers should also make sure that they measure from the correct reference points and account for any potential shifts in the load during transit.
HPMVs exceed a mass of 44,000kg and/or the maximum length dimensions allowed for standard vehicles but meet higher individual axle and axle group limits and are no wider or higher than a standard vehicle.
A vehicle operating on an HPMV permit must carry the permit in the truck, and it must be shown to a police officer on request. It is important to comply with all
conditions, particularly those relating to mass and route.
Get in touch with key agencies to further discuss your unique situation on this critical matter.
Accurately measuring load heights involves using reliable tools such as height poles, laser measures, or height sensors. Truck drivers should also make sure that they measure from the correct reference points and account for any potential shifts in the load during transit.
It’s critical to measure load height correctly, just as truck drivers must receive proper training. Certification programs can provide drivers with the knowledge and skills they need.
Organisations such as the New Zealand Trucking Association offer training and resources to help drivers stay informed and safe. Established in 1988, the Trucking Association serves as a collective voice for trucking operators throughout the country. They work closely with various local councils and government agencies such as Waka Kotahi, WorkSafe, ACC, and other key industry stakeholders and actively address issues that directly impact our members. By investing in proper training, using reliable measurement tools, and staying informed about the latest standards, we can prevent tragic incidents and make New Zealand’s roads safer for everyone.

The nation’s property market continues to shift in favour of buyers and renters, albeit at a snail’s pace. The proportion of properties resold for profit declined even further in the second quarter of 2024.
CoreLogic NZ’s latest Pain & Gain report shows that in Q2 2024, 92.1 percent of properties were resold for more than the original purchase price, down from 92.9 percent in 2024’s first quarter. It’s this statistic’s lowest figure since the third quarter of 2015.
CoreLogic NZ Chief Property Economist
Kelvin Davidson said the shift in market conditions, driven by still-high mortgage rates, stretched affordability, and a surge in listings, highlights the growing influence of buyers in price negotiations.
“Although most property owners continue to make a gross profit at sale, the recent softening in the market has shifted the balance of power away from sellers and towards buyers to some degree,” he said.
“The volume of listings on the market is already sitting at multi-year highs and is possibly set to rise further as some investors who are now Brightline Test-free bring forward their cashflow-negative properties for sale.
“Buyers, particularly those with job security and sufficient financial resources to manage mortgage repayments, could gain further leverage in price negotiations. That means the resale performance achieved by current property owners could remain subdued in the next few quarters.
“The slower housing market in the past couple of years has simply required some owners to hold for longer to achieve their goals.
“However, it’s likely in other instances that longer hold period simply reflects weaker housing sentiment and greater caution, and a desire among property owners to ‘ride out’ the current soft patch before testing the market.”
“That said, the second half of 2024 could still prove challenging for the property market, given that the worst isn’t over yet for the labour market.”
Rental listings up 40 percent
Earlier this year, data from realestate.co.nz showed that rental numbers increased by 40 percent nationally over the April to June quarter, but the number of rental seekers increased by just 2.5 percent.
The website’s data showed Auckland listings up 40 percent, Wellington 56 percent, and Canterbury 35 percent over that quarter. If the trend continues, landlords will consider decreasing rental prices and lengthening leases to stimulate interest.
Buyers have ample choice and time to decide, but this will be a competitive market for many sellers. They should research local market trends and be prepared to negotiate to meet the market.
“Total stock increased during July by 32.3 percent year-on-year to 30,556 properties for sale,” realestate.co.nz reports.
“New listings were also unseasonably high, up 31.3 percent year-on-year, breaking a seven-year trend of low listing levels in July.
Adding to the property market’s winter chill, 10 of our 19 regions experienced a slowerthan-average rate of sale last month.”
CEO of realestate.co.nz Sarah Wood notes that supply was unusually high for July, with almost 7,500 more total homes for sale than this time last year.
“Buyers have ample choice and time to decide, but this will be a competitive market
for many sellers. They should research local market trends and be prepared to negotiate to meet the market.”
“Consumer confidence and interest rate adjustments will likely be key drivers of future market trends,” she adds.
Buyers took their time in July. 10 of the country’s 19 regions saw a slower-than-usual rate of sale in July, signalling that the market is moving more slowly in these regions. The rate of sale measures how long it would take, theoretically, to sell the current stock at the current average rates of sale if no new properties were to be listed for sale.
For example, in Auckland, realestate.co.nz calculations show that it would currently take 40 weeks for all stock to be sold, compared to the long-term average of 23 weeks.
Auckland saw the biggest slowdown of all regions during July.
“The high stock levels we have seen throughout 2024, combined with slower sales, could provide opportunities for buyers. However, this depends on individual circumstances. High interest rates and new debt-to-income ratios (DTIs) could impact their ability to purchase.
“For sellers, understanding current market conditions is crucial. Staying informed, getting advice from your local agent and being flexible can make a significant difference in navigating this slower market,” Sarah explains.

The greater Wellington region is experiencing a surge in building, renovation, and construction projects. This growing demand reflects the region’s economic vitality and its population’s desire for modern, efficient, and sustainable living and working spaces.
As these projects multiply, selecting the best product and service providers becomes crucial, not just for ensuring the success of individual projects but also for maintaining the region’s reputation for high-quality construction standards.
In an industry where the stakes are incredibly high, from the safety and durability of buildings to the aesthetic and functional outcomes that define a project’s success, the quality of products and services cannot be overstated. Inferior materials or subpar workmanship can lead to significant setbacks, both financially and structurally, undermining the integrity of the entire project. In Wellington’s unique environment, where buildings must often withstand the challenges of earthquakes, harsh weather, and coastal conditions, the margin for error is even slimmer.
Wellington’s climate necessitates the use of high-quality, durable materials that can withstand high winds, heavy rainfall, and salty air, particularly in coastal areas. Building with substandard products in such an environment is a recipe for disaster, leading to premature wear and tear, costly repairs, and potentially
By choosing the best providers, the region can make an investment in its future, ensuring that its buildings will stand strong for generations to come and reflect the highest standards of craftsmanship, safety, and sustainability.
unsafe living conditions. Therefore, the best providers are those who offer products that meet or exceed the standards for durability, sustainability, and safety.
Wellington’s older buildings, many of which hold historical or architectural significance, require careful handling and a deep understanding of both traditional and modern construction methods. Renovation
projects must balance preserving a building’s character with enhancing its performance and usability. Achieving this balance requires collaboration with service providers who are experts in their craft and understand the unique challenges and opportunities presented by Wellington’s built environment.
As homeowners and businesses seek to reduce their environmental impact, the construction industry must adapt by offering cutting-edge products and services that align with these values. The best providers are those who are ahead of the curve, offering innovative solutions such as sustainable
insulation materials and smart building technologies that enhance energy efficiency and reduce carbon footprints.
However, the quest for quality should not stop at the materials. The service aspect is equally important. The best providers are those who offer comprehensive service packages that include thorough consultations, transparent pricing, and ongoing support even after the project’s completion. This level of service ensures that clients are satisfied with the final product and also feel supported throughout the entire construction process.
The emphasis on selecting the best product and service providers also extends to supporting a culture of continuous improvement and excellence within the industry. Providers who invest in ongoing training for their staff, adopt the latest industry standards, and actively seek feedback to improve their offerings contribute significantly to the region’s overall construction quality.
As the greater Wellington region continues to grow and evolve, the need for highquality products and services in the building, renovating, and construction sectors cannot be overstated. By choosing the best providers, the region can make an investment in its future, ensuring that its buildings will stand strong for generations to come and reflect the highest standards of craftsmanship, safety, and sustainability.

Auckland, New Zealand’s bustling economic hub, has long been a magnet for builders, renovators, and construction professionals. The city’s rapid growth and development have spurred a surge in demand for top-notch building and renovation services. From historic homes to modern skyscrapers, the need for excellence in products and services has never been more critical.
Auckland’s skyline is proof of the city’s ongoing transformation. With new residential complexes, commercial buildings, and infrastructure projects cropping up, the construction sector is booming. This growth brings opportunities but also challenges, particularly in maintaining high standards of quality and reliability. The rapid pace of construction means that there is always the risk of cutting corners, which can lead to substandard work and long-term issues. Homeowners, developers, and investors must recognise the importance of quality in every aspect of their projects.
Safety should be number one in any construction project. Subpar materials and services can compromise structural integrity, leading to potential hazards. High-quality products and skilled service providers ensure that buildings are safe, durable, and compliant with local regulations. While Auckland is not particularly prone
to earthquakes compared to other parts of New Zealand, safety remains a crucial consideration. Ensuring that buildings can withstand various environmental factors, from strong winds to heavy rainfall, is essential for the longevity and safety of the structures.
Renovation projects often aim to enhance the aesthetic appeal of homes and commercial spaces. Using the best materials and hiring experienced professionals can make a significant difference in achieving the desired look. From sleek modern designs to preserving historic charm, quality craftmanship is key to successful renovations. Attention to detail and a commitment to excellence can transform a space, making it more functional and visually appealing. A well-executed renovation not only improves the immediate living or working environment but also adds the overall character and charm of Auckland’s diverse neighbourhoods.
Investing in top-tier products and services can increase a property’s long-term value. Quality construction and renovations not only improve the immediate living or working environment but also contribute to better resale value. In Auckland’s competitive real estate market, this is a crucial consideration for homeowners and investors alike.
Properties built or renovated with highquality materials and expertise tend to attract more buyers and command higher prices. This long-term value ensures that the investment pays off, providing financial security and peace of mind.
Advancements in technology have revolutionised the construction industry. From 3D modelling and virtual reality to smart home systems, integrating technology can significantly enhance the quality and efficiency of building and renovation projects.
Building Information Modeling (BIM) is a game-changer in construction planning and execution. It allows architects, engineers, and builders to create detailed 3D models of a project, identifying potential issues before construction begins. This leads to more accurate planning, reduced waste, and higher-quality outcomes. By visualising the project in its entirety, stakeholders can make informed decisions, leading to smoother execution and fewer costly mistakes.
Incorporating smart technologies into homes and buildings is becoming increasingly popular. These systems offer enhanced convenience, security, and energy efficiency. Providers who stay ahead of the curve by integrating the latest technologies deliver greater value to their clients. Smart home
systems, for example, allow homeowners to control lighting, heating, security, and entertainment systems from their phones. This level of control and convenience enhances the living experience and adds to the property’s appeal.
Selecting the best product and service providers can make or break a construction or renovation project. Conducting thorough research and seeking references from previous clients is essential. Reputable companies will have a portfolio of successful projects and positive testimonials. Ensuring that the providers you choose comply with local regulations and have the necessary certifications guarantees that they adhere to industry standards and best practices. Effective communication is crucial for any project. Choose providers who are transparent, responsive, and willing to collaborate closely with you throughout the process. This collaborative approach ensures that your vision is realised and that any issues are promptly addressed.
In Auckland’s dynamic construction and renovation landscape, the importance of quality cannot be overstated. Whether building a new home, renovating an office space, or undertaking a large-scale infrastructure project, investing in the best products and services is essential for safety, aesthetic appeal, and long-term value. By choosing reputable providers who prioritise excellence, Auckland can continue to grow and thrive, one quality construction project at a time. The city’s future depends on the commitment to quality, innovation, and integrity in every building endeavour.

The National Association of Women in Construction (NAWIC) Awards is a celebration of the strides women have made in the construction industry, an industry that has traditionally been male-dominated. Despite this historical imbalance, the tide is slowly turning. According to the Household Labour Force Survey (HLFS) data, the proportion of women in the construction workforce has been steadily increasing over the past decade.
This growth is not just in percentage points but also in real numbers, with the female workforce in construction growing from 18,900 in 2013 to 48,600 in 2023, representing a 157.1 percent growth. This rate of increase outpaced the 75.3 percent growth in the number of male workers during the same period.
This increase in the number of women entering the construction sector is not accidental. Industry efforts have been focused on promoting gender diversity, making the sector more attractive to women. These efforts have led to a noticeable uptick in female apprenticeships. As of December 2022, there were 1,926 female apprentices in the construction sector, marking a ten percent increase compared to the same period in 2021.
The National Association of Women in Construction (NAWIC) has been at the forefront of these efforts in New Zealand. NAWIC is a voluntary, non-profit association comprised of individuals working in the construction industry or for businesses that provide services to the sector. The association’s mission is clear: “We need to build a more diverse talent pipeline and break down the barriers (real and perceived) to make it easier for women to join the profession.” The more women that join the industry and progress into supervisory and management roles, the stronger the construction workforce will be in the long term.
NAWIC was originally founded in Texas in 1952 by a group of 16 women. Since then, it has grown into an international organisation with chapters all around the world. In New Zealand, NAWIC has been active since 1996 and has established chapters across the country, from Auckland to Otago. The association welcomes new members from all over New Zealand, and its membership base is as diverse as the industry itself. Members include project managers, planners, designers, architects, engineers, tradespeople, students, apprentices, health and safety managers, and lawyers, among others.
NAWIC is committed to encouraging women to pursue, establish, and sustain successful careers in the construction industry. Their vision is to be the leading voice for women in this sector. To achieve this, NAWIC holds regular events focusing on both technical and professional development. These events are designed to inform women in construction while also promoting networking and information sharing to better the construction industry as a whole. The events are held both in person and online, covering a range of topics relevant to the industry.
The annual 2024 NAWIC Excellence Awards, held on 19 July 2024 at the stunning Tākina Wellington Convention and Exhibition Centre, was a testament to the growing presence and achievements of women in the construction sector. With over 550 attendees from across the sector and the country, the energy and atmosphere were electric. The event was not just a celebration of the award recipients but also a showcase of the appreciation, support, and friendship within the industry.
In a pre-event ceremony, 66 finalists were presented with a beautiful taonga, a symbol of their contributions and achievements. The evening itself saw 32 award recipients, including 12 category winners, being honoured.
Stacey Mendonca, MNZM, Awards Director, co-presenter, and NAWIC co-founder, captured the essence of the evening when she said, “It was a privilege to host a diverse group of amazing finalists, to share the Award recipient’s achievements, and hear from the incredible category winners to the captivated audience.” She added, “The Awards recipients were clearly thrilled, and some shed tears of joy and surprise. The
audience showed their appreciation, inishing with a standing ovation for the Helen Tippett winner, Priyana de Sliver-Currie; it was unforgettable.”
NAWIC President Colleen Upton OMNZ echoed these sentiments, expressing her pride in the event and the achievements of the women honoured. “I am struggling to put into words how proud I am of the 2024 NAWIC Awards. So much awesomeness in one room! It was a night to remember, not just for award recipients but for all those who attended. As our award winners spoke, I could not help but think ‘A woman with a voice is, by definition, a strong woman.’ We certainly saw a lot of them on Friday the 19th of July!”
The 2024 NAWIC Excellence Awards not only celebrated the achievements of women in construction but also highlighted the ongoing commitment to building a more diverse and inclusive industry in New Zealand. As the sector continues to evolve, women’s contributions will undoubtedly play a crucial role in shaping the future of construction in Aotearoa.

Ara Rau, the Construction and Infrastructure Workforce Development Council, writes that the long-term prospects for the construction trades have never been better.
This year has seen a regular stream of bad news about construction project delays, cutbacks, and workers leaving for Australia. It’s not hard to become pessimistic about the industry's prospects.
For young New Zealanders considering their career options, this uncertainty may be a deciding factor in choosing not to pursue opportunities in building and construction. But that would be a mistake.
Last month, a summit called Future State was held in Auckland to explore how technology will transform work in the coming decades. One of the speakers was Professor Scott Galloway from New York University, an expert on how people will earn a living in the future.
When asked what he thinks a hot career choice would be today. His unequivocal answer? The trades.
His point was that, unlike those whose jobs could be taken by AI and similar technologies, people with practical skills like plumbing, electrical, and building will not only have the lion’s share of future job opportunities, but they will also command increasingly big pay packets.
We’ve helped a number of Kiwis enter the industry by listening to employers and developing training and qualifications that deliver the skilled people they need.
Although he was speaking about the US, the long-term outlook for the trades is just as strong here in New Zealand.
Over the next five years, we’ll need to build more than 122,000 homes to keep up with
population growth. Beyond residential, we have a national pipeline of construction and infrastructure projects, from building hospitals, transport connections, electrification, and associated new infrastructure for generation, networks, and technology to increasing our resilience against weather events. Plus, upgrades are needed for sustainability and retrofitting existing homes and buildings. We don’t have enough skilled people to get all this work done.
Waihanga Ara Rau Construction and Infrastructure Workforce Development Council is the organisation tasked with growing the workforce we need. Established in 2021, we’ve helped a number of Kiwis enter the industry by listening to employers
and developing training and qualifications that deliver the skilled people they need. As the bridge between the industry and training providers, we are positioned to tackle New Zealand’s shortage of skilled workers in building and construction. As the voice of people in Construction and Infrastructure, we want to see career pathways and progression for the current workforce and career changers.
What’s clear to us is that the current downturn is temporary. We’re urging the industry to be positive about the future and for young Kiwis and their parents to understand that a young person with a trade can look forward to high demand for their skills and a range of career opportunities with strong earning potential.
Together we can shape the future of construction and infrastructure. Find out more at www.waihangaararau.nz
Demolition can harbour a silent threat – asbestos. This fibrous mineral, once widely used for its fireproofing and insulating properties, is now recognised as a deadly carcinogen. Inhaling asbestos fibres can lead to a multitude of life-threatening diseases, making safe and compliant demolition procedures crucial. The danger lies in the very nature of demolition itself. The act of tearing down a building inevitably disturbs and breaks apart materials. If these materials contain asbestos, the demolition process releases microscopic fibres into the air. These fibres are invisible to the naked eye, yet they pose a significant health risk. Once inhaled, the fibres can lodge themselves deep within the lungs, causing long-term damage that may not manifest for decades.
The consequences of asbestos exposure can be devastating, and the latency period for these diseases, meaning the time between
exposure and the onset of symptoms can range from ten to 40 years. This long delay can lull victims into a false sense of security, only to be confronted with debilitating illness decades later.
The dangers of asbestos are not confined to demolition workers. Airborne fibres can travel far from the demolition site, potentially exposing bystanders, residents in neighbouring buildings, and even family members who come into contact with contaminated clothing.
Fortunately, strict regulations and safety protocols exist to minimise the risks associated with asbestos in demolition.
The key to ensuring a safe demolition process lies in the expertise of qualified asbestos removalists. These professionals possess the knowledge and training to identify asbestos-containing materials (ACMs) within a structure.
The New Zealand Demolition Asbestos Association (NZDAA) plays a vital role in promoting safe practices within the industry. Its website (https://www.nzdaa.com/) provides valuable resources for demolition contractors and homeowners.
The actual removal process is a highly specialised task undertaken by trained
The key to ensuring a safe demolition process lies in the expertise of qualified asbestos removalists. These professionals possess the knowledge and training to identify asbestos-containing materials (ACMs) within a structure.
asbestos removalists. These workers wear appropriate personal protective equipment (PPE), including respirators, to prevent inhalation of asbestos fibres.
The removal process typically involves containment measures to prevent the spread of asbestos fibres. This might include sealing off the work area with plastic sheeting and utilising negative pressure to create an airflow that draws contaminated air towards a designated filtration system.
Once the asbestos removal is complete, a clearance certificate is issued by a qualified
inspector. This certificate verifies that the area is free of asbestos contamination and safe for further demolition work to proceed.
The dangers of asbestos in demolition cannot be overstated. Exposure to these fibres can have life-altering consequences. By adhering to strict regulations, utilising qualified asbestos removalists, and diligently following safety protocols, we can ensure that demolition projects are carried out in a safe and compliant manner, protecting both workers and the surrounding community.

Ten years ago, New Zealand’s structural steel industry turned its attention to quality and compliance in earnest.
Since then, it has delivered numerous initiatives to drive best practice and help ‘raise the bar’ across the sector.
Today, as a result, the structural steel sector is widely considered to be leading the building industry in the quality and compliance space.
The Bolt Importer Charter (BIC) is the latest steel construction industry quality assurance programme.
It complements the Steel Fabrication Certification programme launched in 2014 and the Structural Steel Distributor Charter launched in 2019.
“The Bolt Importer Charter ensures that good procurement practices are applied to sourcing and supplying anchor bolts and fasteners to the local steel construction
market,” says Kevin Cowie, Technical Director, Steel Construction New Zealand.
“It’s a mark of excellence for bolt importers in New Zealand.”
Having been independently audited to satisfy the requirements, Würth is one of the first companies to adopt the BIC and hold itself to this higher standard.
“Quality is very important to Würth, so when we heard about the Bolt Importer Charter, we were excited to learn more,” says Brendon Adam, National Product manager, Würth.
The team discovered its quality standards were already very close to the Charter’s requirements, particularly in the areas of third-party lab testing and certification, batch tracing practices, and running an accredited, independently audited quality management system (QMS).
“It was a natural step for us to join the scheme.”
Würth approached the initial BIC audit with curiosity and an open mindset.
structural steel contractors,
with non-compliant bolts.
The Bolt Importer Charter ensures that good procurement practices are applied to sourcing and supplying anchor bolts and fasteners to the local steel construction market.
“Anyone familiar with QMS audits will surely admit, it can feel a little nervewracking to have your processes scrutinised in such detail, but the end result is always extremely valuable,” says Brendon.
Brendon notes that, as industry awareness of the scheme grows, the BIC is becoming less of a ‘nice to have’ and more of a ‘need to have’.
For good reason. The BIC has the potential to significantly improve the quality and safety of the New Zealand construction industry.
“Ensuring bolts meet necessary standards can prevent failures and accidents during construction and in the final structure,” says Brendon.
“It provides builders, specifiers and end users with confidence in the integrity of the structural components.”
Consistent quality also reduces rework, repairs and delays, leading to more efficient and cost-effective projects, says Brendon.
“Last but not least, by encouraging responsible sourcing, the scheme promotes fair competition and discourages the use of unsafe or substandard products.”
Brendon appreciates that opinions relating to price versus quality vary from company to company.
“But I’m sure all would agree that a lowest quality, lowest price model is not the correct strategy for the importation and sale of structural fasteners.”
He remains hopeful that this common understanding will drive interest in and uptake of the Bolt Importer Charter.
“The market is becoming more and more focused on compliance and the Bolt Importer Charter is another commitment by our structural steel industry to maintaining a higher benchmark,” says Wayne Carson, Managing Director, D&H Steel Construction.
“It gives clients confidence. For structural steel contractors such as us, it minimises the risk of being supplied with non-compliant bolts and, importantly, it reduces the risk for those responsible for signing off on a building’s compliance,” he says.
The market is becoming more and more focused on compliance and the Bolt Importer Charter is another commitment by our structural steel industry to maintaining a higher benchmark.
Wayne applauds Würth’s achievement. With it, he says, the Charter has now attained the critical mass to propel it forward. He encourages all bolt distributors to step up.
“D&H will increasingly prioritise the Bolt Importer Charter as a requirement of our suppliers,” says Wayne.
He urges other structural steel contractors to support those that are demonstrating a commitment to supplying quality and compliant bolts.

Transitioning the construction sector to a circular economy is not just about reducing emissions today but ensuring our buildings and materials are part of an ongoing cycle that benefits future generations.
Many of the discussions about carbon and, indeed, carbon calculation, focus on modules A – C life cycle assessment processes. In fact, there is often a lack of robust data about the end-of-life and beyond-carbon impacts, which limits meaningful assessment of impacts (or benefits) in these stages of construction.
We obviously need to decarbonise our built environment now in order to meet our national carbon reduction targets and address the challenges of the climate crisis. MBIE’s Building for Climate Change initiatives are a step in the right direction and rightfully focus on whole-oflife emissions.
If we don’t start to think more about the circularity of our buildings and their component systems and materials, we risk solving our immediate problem and then
deferring the problem for the next generations to deal with when our building stock being built now comes to the end of its life.
We need to solve both problems. How do we get carbon out of the buildings we are constructing now and how do we ensure that we are not then deferring the problem to the end of their life? This is where circular design, as a component of Construction 4.0, becomes important. That is, how do we design for reduced end-of-life carbon?
To do this, we need to stop thinking about the lifecycle of a building and think of the lifecycles of a building and its materials; this is circular economy thinking.

Metspray, based in Auckland, has an exciting state-of-the-art coating facility underway. The facility will improve Metspray’s sustainability and health and safety outcomes and increase its capacity for abrasive blasting and industrial coating massively.
Scheduled to open November this year, Metspray Director Chris Schultz-Merrick says that they’ll “be able to maintain temperature and humidity precisely to streamline the coating process. Additionally, air drawn through the facility will be filtered to remove particulate – on its way in, and out”. All of this will contribute to a healthier place to be for staff, clients, and the wider community.
“The combination of the air filtration, temperature, and humidity controls we’ll have in place will improve our sustainability outcomes on multiple levels. On a particulate level, the blast air that’s discharged to the natural environment will be completely clean air. We’ll regulate temperature and humidity at levels that prolong surface preparation and accelerate coating curing. This will translate to less inputs and less waste, as well as reduce processing times. Because each service zone, and the entire facility will be contained, with trucks entering through rapid doors, maintaining temperature and humidity will use less energy. Used steel abrasive will go through a series of filters and be recycled on-site, so you’re looking at a process with significantly less draws on natural resources.”
The facility at Drury is being purpose-built for abrasive blasting, protective coating, intumescent coating, and thermal zinc/aluminium spraying of structural and architecturally designed steel, infrastructure assets like bridges and pipelines, heavy machinery, and marine vessels and equipment. With a bespoke design comes the potential to implement more sophisticated health and safety practices, and Metspray has taken this and run with it.
“Our offices will be centralised to one building at the front of the facility with contained service zones behind and to the back. Forklifts will be confined to their designated zones and trucks, directed to the relevant zone. Staff exposure to moving vehicles will be minimised, mitigating the risk of logistics-related incidents. We’ll utilise flat racks for unloading and loading steel - one crane lift per load. Our yard guys and the truckies we work with are extremely careful when working together to load large pieces of steel that often weigh close to 10tonne. With flat racks, they’ll be exposed to less lifts, reducing the probability of lifting incidents, and loading and unloading will happen a lot faster.”
Thanks Chris, for talking us through the improvements to sustainability and health and safety that your facility at Drury will bring. But what about capacity—will it increase Metspray’s capacity to handle work?
“Our East Tāmaki facility has the capacity to blast, prime, and topcoat 4,500m2 of substrate weekly. When Drury is operational that number will increase to 12500m2 at optimal productivity and 14,500 at capacity. That’s a significant increase in the amount of work we can process, not to mention the rate at which we can get it done. We’ve been operating at capacity for a while now. Our new facility will enable Metspray to meet market demand for present and future coating projects”.

All products and processes utilized in the manufacture and erection of a steel structure need to have some degree of quality control, quality assurance and compliance certification.
The Building Act is the governing legislation, and Standards, Specifications, and Codes of Practice usually define a mechanism for complying with the Act.
It is well recognized and understood that the raw steel materials must be accompanied by material certificates, and AS/NZS materials can only be certified if the certificates are ILAC MRA endorsed by an accredited organization.
What does this mean? Accreditation is “the independent evaluation of conformity assessment bodies against recognised standards to carry out specific activities to ensure their impartiality and competence”. ILAC stands for “International Laboratory Accreditation Co-operation”. New Zealand’s Signatory to ILAC is IANZ (International Accreditation New Zealand) while in Australia it is NATA, CNAS in China etc.
Other aspects of safety and building legislation require accreditation for compliance testing for example plant that falls under the PECPR (Pressure equipment, cranes and passenger ropeways) regulations.
With local fabrication, welding and coatings there are many aspects that can benefit from engagement of an accredited organisation to perform inspections.
The benefits of using accredited suppliers…
Independent verification of:
• Competence and certification of personnel, including eyesight
• Quality systems to ISO 9001 and ISO 17020/17025
• Equipment suitability and calibration
• Documented procedures
• The correct extent of testing being applied
• Reporting which meets the requirements of the standards
• Assurance of Impartiality and confidentiality
With Overseas production of fabricated steelwork we often rely on quality records and third party inspection done in the overseas factory. However overseas manufacturing practices are often very different and may lead to non-conforming products and poor quality documentation.
Therefore it is often necessary to have an auditor specifically appointed to review the fabrication, welding, coating and inspection work done overseas to mitigate project risks such as:
• Raw materials procurement which lacks traceability
• Production processes which do not comply with NZ standards
• Personnel (welding and inspection) who do not hold appropriate certifications and accreditations
• Quality records which are inadequate
• No adequate procedures to ensure impartialityof quality personnel
• Inappropriate procedures and workmanship not complying with AS/NZS standards
• Incorrectly applied local standards
Any of the above may give rise to rejection of product after it reaches New Zealand!
In auditing of overseas steel fabricated steel we frequently come across certificates and
test reports from overseas organisations which are deficient.
We have seen:
• fraudulently produced steel certificates
• unqualified personnel operating outside their proven skill set
• uncalibrated and unsuitable equipment
• serious departures from standard or specification requirements.
In Summary:
All local compliance inspection of welding, bolting and coating should be carried out by qualified or certified personnel working within an accredited company;
Overseas procurement of fabricated steel should be reviewed and audited by an experienced New Zealand based inspection company well versed in all the requirements of the applicable New Zealand standards.

that continually cycles materials through the supply chain. Transitioning the construction sector to a circular economy is like rethinking how we handle our personal belongings: instead of buying and discarding, imagine a wardrobe where every piece of clothing is designed to be easily repaired, reused, or recycled into something new, ensuring nothing ever truly goes to waste.
What do we need to make a circular economy for building materials?
Steel is already a rockstar of Aotearoa, New Zealand’s circular economy. In fact, in the HERA Steel Recycling Report undertaken by thinkstep.anz, it was found that 85 percent of our construction steel is already being recycled, providing a net benefit of about 793,000 tonnes of CO2 equivalent each year.
At HERA, we are reimagining buildings as banks of materials. The materials used in the building then become available for “withdrawal” at a later date.
This means that:
• design for re-use will become important –we will need to change the way we design. For example, it may mean less welding and more bolting to make disassembly simpler;

In order to re-use a material, we need to have reliable and transparent data about its fitness for re-use. This is why a material passport is required. A material passport provides a digital inventory of all the materials used in an object (e.g., a building, a structural system or element), along with any data that is important to enable use in a circular economy.
For steel, the likely considerations required of a material passport are shown above. A material passport does not currently exist, but HERA is in the process of developing one for steel.
What does the future look like with material passports?
At HERA, we are reimagining buildings as banks of materials. The materials used in the building then become available for “withdrawal” at a later date.
• building health monitoring will provide valuable data – we will require more data about the events that a building is exposed to, such as earthquakes; and
• business models will become circular. Wow! The options here are endless but the potential for business model innovation is clear. For example, would fabricators lease out their columns or would they buy them back at end of life and re-purpose them?
It is easy to see how Construction 4.0 technologies will assist the development of material passports. Key enabling technologies, which are all within the wheelhouse of Construction 4.0, would include AI, digital twins, scanning, blockchain, Construction 4.0, AR, machine learning, BIM, optimisation of circular design, and NDT (these will need to be developed and dealt with in the regulations to facilitate versus hinder re-use).
Auckland’s CAB building is an example of adaptive re-use, whereby retaining its 18-storey structural steel frame saved 6,150 tonnes of carbon.
A case study: adaptive re-use that could have benefited from a material passport
Auckland’s CAB building is an example of adaptive re-use, whereby retaining its 18-storey structural steel frame saved 6,150 tonnes of carbon.
When the building was constructed, the details of the steel used would have been documented and known (i.e., “identified”) but through the passage of time, the mechanical and chemical properties would have been lost, leading to an “unidentified status”.
This would have required extensive investigation to ensure fitness for retention, estimated to have cost in the vicinity of $60k direct costs and three months delay. Having a steel material passport in play (and the regulatory system in place to work with it) would have greatly assisted.

A substantial consultation on work health and safety presents a roadshow across the regions over the coming months, says Workplace Relations and Safety Minister Brooke van Velden.
This the first step to deliver on the commitment to reforming health and safety law and regulations, set out in the ACTNational Coalition Agreement.
“Our health and safety culture can be summed up by the sea of orange road cones that have taken over the country. From Santa parades to property development, you can’t get a lot done without having to set up a barricade of cones.
“While they may improve health and safety in some places, in other situations their prevalence just doesn’t make any sense.
“Businesses and community organisations spend a huge amount of money trying to keep people safe, but it’s worthwhile asking: are the rules and expectations proportionate to the actual risks, and when should common sense prevail?
“Lawyers and company directors should not have to be kept up late at night anguishing over what ‘so far as is reasonably practicable’ means.
“That’s why we’re holding this consultation and also why I am travelling across the country in the coming months to hear from businesses and workers who are impacted by the current rules and regulations. I want to listen to experiences with our work health and safety system, including what they think the role for government should be and where they think we’ve got the requirements right and wrong.”
The Government is seeking feedback on people’s experiences with the health and safety system, including views on issues such as:
• Whether health and safety requirements are too strict, or too ambiguous, to comply with
• Difficulties caused by the overlap between work health and safety legislation and other requirements
• The actions that businesses undertake, the reasons behind these actions, and their effectiveness
• Whether consequences for not complying with health and safety obligations are appropriately balanced and reasonable
• Whether the threshold at which workrelated risks need to be managed is under- or over-cautious.
“New Zealanders expect and deserve to have their family members return home safe and healthy at the end of each and every workday. Where we have to follow rules to keep ourselves or others safe, those rules should be clear, sensible and proportionate to the risk,” Van Velden says.
“The actions businesses and workers need to take to protect health and safety should be appropriate and meaningful, rather than just another tick-box exercise.
“I look forward to meeting Kiwis across New Zealand and hearing their views directly.”
NZCTU Te Kauae Kaimahi president, Richard Wagstaff, is calling on the minister to ensure that her review places the voices of workers front and centre.
“Everyone in Aotearoa New Zealand has the right to a safe workplace and to be able to come home safely to their family at the end of the day. That must be the number one priority of any review to health and safety laws,” Richard says.
“This review must include robust consultation and engagement with workers and their unions, to ensure best practice health and safety. It is workers who bear the brunt of poor health and safety, the people doing the work are the best placed to understand risks.
“I am concerned that the announcement of this review foreshadows a weakening of a long-standing consensus on improving workplace health and safety in New Zealand.
“This review is a great opportunity to strengthen New Zealand’s approach to health and safety. Some easy wins for the Minister would be to ban engineered stone and introduce corporate manslaughter legislation,” said Wagstaff.
BusinessNZ has expressed its support of the review. “Feedback from member businesses tells us that in many instances the health and safety regulations pertaining to their industry can be too strict, too loose, too many, too few, disproportionate to the risk, ambiguous, unreasonable or just not sensible. Meanwhile, the protection of staff from health and safety hazards in many cases remains at risk,” it says.
Transporting New Zealand interim CEO, Dom Kalasih, has welcomed the announcement.
“Over the past few years we’ve been raising our concerns that there’s not enough recognition that the actions of other parties in the supply chain have significant influence on the behaviour and operational practices of our members, who are providing road freight services.”
Kalasih says delays at customer points, such as when picking up or dropping off loads can significantly impact driver schedules, and that can have flow-on effects to drivers meeting regulatory requirements like driving hours.
“In similar fashion, if the infrastructure at truck pick-up and destination points is not designed and maintained well, then drivers face increased risk to their health and safety when loading and unloading.
“We’re also concerned at the growing number of cases where there seems to be less consideration and fundamental thinking about risk management. The focus of some regulators appears to be dominated on compliance with a particular system rather than how effective and appropriate it may be at managing the risk to health and safety.
“It worries me we’ve gone through a period where people can’t see the wood for the trees.
“We’ve been advocating for a return to a sensible risk approach, so it is good to see the coalition government taking this step and we will be providing a formal submission on this.”
By Glenn Dobson, CEO, The Drug Detection Agency
It is critical for contractors to manage the risks of drugs and alcohol in the workplace during an economic downturn.
Research shows that substance related work incidents increase during a recession, a point supported by the fact that drug use and alcohol sales are considered ‘inflation resistant’.
Recent data from The Drug Detection Agency’s (TDDA) own database, Imperans, shows a steady year-on-year increase in positive workplace drug and alcohol detections. While times are tough and workplace risks are on the rise, it is paramount for businesses to stay up to date with drug trends, as well as conduct drug and alcohol testing and education, to foster a safe workplace. I recommend building and contracting companies review their substance policies, maintain or implement testing programmes, and engage professional educators for drug and alcohol awareness training.
Don’t try cheap. Unaccredited suppliers, DIY kits and in-house testing risk a company’s reputation and costly court battles, and compromise employees’
safety. When properly conducted, drug testing and health and safety education are critical tools for managing drug-related risks in the workplace.
Cutting costs around health and safety creates a lose-lose situation, leaving building businesses and their owners at risk of being non-compliant with the Health and Safety at Work Act 2015 (HSWA).
Poor quality testing and a lack of qualified processes can lead to an employee being wrongly accused of substance use or the failure to identify someone affected by substances. When people operate heavy equipment and work in the contracting and building trade, there is no room for testing errors. When an improper procedure compromises test quality, you open the door to serious injury – or even a fatality.
Especially during challenging economic times, companies need an independent, accredited service provider to deliver accurate and professional third-party testing. This demonstrates that a company is serious about maintaining a safe working environment and the wellbeing of its employees. Do not take shortcuts when people’s lives and livelihoods – and your company’s reputation – are on the line.
When people operate heavy equipment and work in the contracting and building trade, there is no room for testing errors. When an improper procedure compromises test quality, you open the door to serious injury –or even a fatality.
TDDA and its Imperans database allow employers to base their testing and policies on real-time data and accredited best practices. TDDA offers educational workshops for businesses and their employees, including the Comprehensive Substance Identification Training and recently launched Advanced Drug Awareness Training. These training sessions ensure every member of a workforce is equipped to maintain workplace safety and empowered to successfully identify and manage situations arising from drug and alcohol use and abuse.
TDDA offers a wide range of drug and alcohol tests to suit businesses, including Breathalyser technology in its mobile clinics, hair alcohol testing and multi-panel substance tests to help companies prioritise their employees’ wellbeing and maintain a safe and compliant workplace.

The Hire Industry Association of New Zealand Inc. (HIANZ) has a long-standing tradition of holding an annual conference for its members. This year, the conference adopted a new name: HIRECON24.
An association conference is a time to meet up with like-minded people with the same challenges and opportunities. It’s a place where competitive thoughts are dropped in replacement for learning and supporting each other to be successful in your chosen field. Leveraging ideas, learning and building networks are the core benefits of attending.
HIRECON runs a two-day format of educational and informative sessions, as well as running a communal exhibition space.
HIRECON24 showcased over 55 exhibitors from the plant and equipment supply chain, displaying a wide range of “good for hire” items, from tablecloths to tents (marquees), chainsaws to chippers, battery drills and bubble machines, boom lifts, and bucket loaders. Everything related to plant and equipment was on display.
Additionally, all the supporting services crucial to a successful hire business were on display, including rental and fleet management systems and software, insurance services, and financial and legal support.
The Viaduct Events Centre in downtown Auckland, formerly used as Team NZ base for the America’s Cup, was an excellent venue for this year’s conference. With meeting rooms, a large plenary and an impressive exhibition ideal for showcasing heavy machinery, it provided the perfect setting. Over 400 attendees benefited from attending the event.
In addition to its full program, HIRECON24 ran two competitions aimed at promoting a safe, competent, and productive industry.
The National Forklift Operator Championship took place regionally throughout May and June, culminating in national finals at the conference with the top five operators. Competitors were evaluated based on their theory, pre-operational checks, and practical elements of safe use skills. Anthony Allen from Booths Logistics in Hastings emerged as the winner.
The other competition aimed to promote marquees as a great space to hold an event. Party and event sector members competed to see who could build a marquee the fastest whilst complying with the requirements of the industry’s best practice guidance. If you are planning to use a marquee for your event, be sure to choose a hire company accredited to the Apex marquee best practice standards. This year, the X-Site Group North Island team claimed an impressive win.
The education sessions offered something for everyone, covering topics such as succession planning, balance sheet strengthening, family business advice, cyber
security and strategies for working with and developing your staff, all aimed at helping delegates improve their business position. The conference finishes off with the prestigious Hire Excellence Awards. The awards night celebrates those in the industry who are excelling in a range of categories. Not only are the category winners celebrated, but also the overall winners. You can find further information on the winning businesses for 2024 on our website: www.hianz.net.nz/hire-excellence-2024
If you have a gap between what you have and what you need when it comes to plant and equipment, seek a HIANZ member to provide the solution to your problem.
The proverbial Kiwi dream has, for many years, been built on a quarter acre section. But with soaring energy costs, the new Kiwi dream is less about section size and more about energy efficiency.
But energy-efficient homes are expensive, right?
Not so, according to the Superhome Movement, an organisation spearheading energy-efficient buildings and aiming to dispel misconceptions about energy efficiency’s affordability.
The Superhome Movement is a not-for-profit building industry group of professionals whose passion is to raise the standards of new homes. It includes, builders, developers, designers and architects, and product suppliers.
Co-founder of the Superhome Movement, Christchurch architect Bob Burnett says, “It’s a myth that a superhome is too expensive. More and more people are realising that a superhome is affordable.”
“Superhomes are built to a higher energyefficiency standard than what the NZ Building Code requires. That means the power bills are much lower than standard new homes, and they have higher levels of insulation and ventilation meaning they are healthier too.”
“And it only costs an additional $5,000 to $6,000 for an average-sized new home to be built to the standard of a Superhome.
“With smart design that extra cost can easily be met by reducing the floor area of a new home by a small amount – three to five square metres,” Bob says.
At its core, the Superhome Movement is all about providing the best in education, products and expertise to help people build warm, dry, healthy, energy efficient and environmentally sound homes.
Bob was in the process of building what would later become the first 10-star home in New Zealand at 9 Church Square in Christchurch.
The secret to having no power bills are the 18 photovoltaic (PV) solar panels which power a heat pump that multiplies the PV power by four. This thermal energy is then stored in the unique hot water cylinder and fully insulated concrete slab, with salt water battery power as a back-up energy storage solution.
Superhome key principles:
• Design - optimised for orientation, function, and aesthetics
• Modelling - verify energy performance and thermal comfort
• Windows and doors - highperformance, in line with insulation
• Structure - super-insulated with minimal thermal bridging
• Slab foundations - fully insulated and resilient
• Airtightness - appropriate techniques and standards
• Ventilation - appropriate whole home heat recovery systems
• Materials and waste minimisationlow carbon, responsibly sourced, and specified
• Energy-efficient space heating and water heating
• Water efficiency and recycling.
A daylight sensor means the system is off at night, and by eliminating thermal bridging or leaked heat, 20°C is maintained even when there is frost outside.
The 140sqm home uses a new Gibfix® framing system, which significantly reduces the amount of timber used, allowing room for additional insulation.
The design includes insulated edges of the concrete floor slab, a solar wall linked to an energy recovery ventilation system and recessed European style uPVC windows, combined rain-water and grey water systems,
water-efficient fittings and a solar-powered electric-car charging port.
“It’s not just about being able to look at the home, because a lot of what this home is about you can’t see. It enables you to get a behind-the-scenes presentation.”
Four steps to planning your Superhome
1. Plan early and do your research. Think about the site location and the home’s design and orientation to the sun. Be size efficient, and build just what you need. Quality, not quantity
2. Get the right team. Find an architectural designer who is experienced in designing for health, comfort, resilience, and low carbon footprint. A good architect or designer will add huge value and save you thousands in running costs. They will help find a builder who is experienced in building better. Beware of greenwash
3. Invest in the thermal envelope first, including airtightness, an edge-insulated slab, uninterrupted insulation in the walls and ceilings, high-performance windows, and proper ventilation
4. Be sustainable in your choice of building materials. Think of the generations of people who will live in the home after you are gone and what will happen to the home in 100 to 200 years.

BCITO has launched a website aimed at demonstrating the opportunities for deaf New Zealanders in the construction industry.
The Building Abilities site features stories of Kiwis who have succeeded in BCITO apprenticeships and gone on to careers in the building trades. It also features resources from BCITO and Deaf Aotearoa to help learners and employers.
The site was launched to coincide with New Zealand Sign Language Week (May 6-12).
More than 4,500 deaf people use New Zealand Sign Language (NZSL), and around 23,000 New Zealanders across the country use it regularly.
However, a lack of awareness about deaf people’s abilities remains a significant barrier to work.
Deaf Aotearoa chief executive Lachlan Keating says, “Sometimes employers have no experience or knowledge of deaf people and/ or NZSL, so they are hesitant. Yet more often than not, deaf people begin a job, and the employer realises that the deaf individual is more than capable of doing the same work as their hearing workmates.”
While exact figures around the number of deaf people who are unemployed or underemployed are unknown, the employment rate for all New Zealanders with disabilities is half that of the general population. This includes members of the deaf community.
BCITO director Greg Durkin says, “Providing all learners with the right resources to have meaningful careers in construction is our reason for being, and we’ve focused on developing strong partnerships with organisations such as Deaf Aotearoa to break down those misperceptions and barriers.
“At a time when the industry is still facing a shortage of skilled workers, we need to do everything we can to inspire and empower more people to consider a trades career or gain a trade’s qualification.”
Bottom of Form
Barry (Baz) Kay is one of the former BCITO apprentices whose story appears on the Building Abilities site. Profoundly deaf since birth, he spent more than 20 years filleting fish because a lack of support during schooling had left him with literacy issues and a perception that he’d only be able to do low-skilled work.
Through a family friend who happened to be a builder, he found a position as an apprentice at Invercargill’s Trent Builders and received support from BCITO to complete his qualifications in 2019.
“My Training Advisor, Andrew Green (BCITO principal advisor - Learners with Disabilities), supported me through the process. He visited me every two weeks to go through the things that were challenging me.
“This included using imagery to define building terminology and explaining certain words that I wasn’t able to understand. My wife would help out by translating into sign,” Baz explains.
At a time when the industry is still facing a shortage of skilled workers, we need to do everything we can to inspire and empower more people to consider a trades career or gain a trade’s qualification.
Since then, he’s become a highly skilled carpenter and valued employee, and he’s keen to help dispel the misconceptions employers can have about how much deaf people can do.
“Deaf people have very good eyes – they’re very visually orientated and are very good with their hands. A lot of deaf people do have barriers in employment, so it’s worth giving people an opportunity and treating deaf people the same as hearing employees as well, because the only difference is that we can’t hear,” Baz says.

The Acceptable Solution for weathertightness E2/AS1 is a solution for claddings on timber frame structures and is not applicable to other non-framed structural systems such as concrete masonry.
NZS 4229:1999 Concrete Masonry Buildings not Requiring Specific Design is cited under the Acceptable Solutions for Clause B1 Structure of the New Zealand Building Code. Although NZS 4229, Clause 2.3 outlines surface coatings for waterproofing of concrete masonry, the Standard is not cited as an Acceptable Solution for weathertightness under the Acceptable Solutions for Building Code Clause E2.
Designers must therefore satisfy themselves of the adequacy of surface coatings for weathertightness and present the solution for acceptance by the building consent authority.
It is worth noting that, ordinarily, coatings are designed to prevent moisture from being absorbed through the surface of the blockwork.
Where the masonry design might be subject to unusual microcracking at block joints, either a surface coating with the capacity to bridge these joints must be used, or other provisions put in place to accommodate the movement.
NZS 4229 does offer some guidance as to surface coatings that have been considered adequate by a Standards committee, but these nevertheless remain as alternative solutions, and outside the Acceptable Solutions and Verification Methods for automatic acceptance by BCAs.
Designers must also consider other weathertightness issues such as joints around openings, building junctions and movement control joints, which will require special weathertightness considerations and must be included in the documentation with applications for building consents.
It is therefore essential for designers to have the details for weathertightness included in the building consent documents, and notify the consent authority of variations that may be made throughout the passage of the work
While structural requirements for the durability of concrete masonry are for not less than 50 years, the waterproof coatings are required to last a minimum of 15 years under Clause B2(b)ii... where failure could be detected during normal maintenance.
While it is necessary for protective coatings to perform for the life of the building, individual coatings are not required to do so.
It is the building owner’s responsibility to ensure that the building continues to comply with the Building Code, and this places the responsibility on them for continuing maintenance or replacement, in this case, of the surface coatings.
Under the Building Act 2004, code compliance certificates will be issued on the basis that work complies with the consent documents.
It is therefore essential for designers to have the details for weathertightness included in the building consent documents, and notify the consent authority of variations that may be made throughout the passage of the work.
Information sourced from: www.building.govt.nz
Many factors contribute to problems with weathertightness. Poor design, poor project management and poor building practices play a role.
The exposure of New Zealanders to international design trends and materials has led to a wider range of housing styles, but some house designs and materials are unsuitable to specific site conditions.
Some house styles and features designed for dry climate locations have been used in areas of high wind and rainfall. Features such as parapets, decks and pergolas that penetrate a dwelling’s cladding contribute to weathertightness risks, as does monolithic cladding, low-slope roofs, membrane roofs, a lack of eaves and complex junctions, especially when these are used in wet and windy conditions.
House claddings do leak. That becomes an issue when the water is not dealt with effectively and affects the integrity of the house.
The Canadians developed the 4Ds philosophy of weathertightness – deflection, drainage, drying and durability. In New Zealand we have adopted those principles, but we now also consider airtightness, ventilation and insulation.
The ideal is to achieve all 4 Ds. Deflection devises (such as cladding and window head flashings) intercept water at a building’s exterior and deflect it away from critical junctions.
Wall assemblies need to be designed and built with protected cavities to incorporate drainage to allow any water that may have penetrated the exterior cladding to drain down the back of the wall cladding and out.
The amount of drying that occurs depends on the cladding type and the way it is installed and all components of a cladding and wall assembly must meet the durability requirements of the Building Code.
Features of a leaky building
1. Ground clearance: Inadequate cladding clearance to ground, paving or decks or insufficient fall away from building perimeter. Clearance to solid ground (concrete, asphalt, paving, decking timber) should be 150mm; clearance to soil 225mm.
2. Cracking: Look for hairline cracks in the cladding, typically found close to windows and doors or discolouration of cladding around these areas.
3. Joinery: Check for cracks along the joinery seals which can allow water ingress.
4. Penetrations: Check all penetrations in the cladding, for example around pipes, vents and meter boxes, for gaps and lack of sealant. Also check to ensure meter boxes are flashed correctly - the lack of flashing or reliance on sealant may allow water to penetrate.
5. Pergolas: Pergola frame penetrating the cladding or directly fixed through the cladding may result in water ingress.
The Canadians developed the 4Ds philosophy of weathertightness – deflection, drainage, drying and durability. In New Zealand we have adopted those principles, but we now also consider airtightness, ventilation and insulation.
6. Windows: Check window flashings to ensure they are correctly installed. Round, shaped or corner windows are difficult to flash, increasing the risk of water ingress. Check for staining below the window.
7. Enclosed Balcony / Cantilever Deck: Enclosed balconies and cantilever decks can result in a multitude of risks. (a) A lack of fall on the balustrade, (b) Handrailings attached through the plaster cladding, (c) Poorly applied waterproof membrane, (d) Insufficient drainage holes allowing water to pool after rain, (e) Lack of clearance between the cladding and the balcony floor - all are signs that water may be penetrating the building’s exterior.
8. Interior Signs: These can include swollen or cracked skirting boards or architraves; mould on the inside of curtains and window liners; floor coverings showing signs of water damage; and swelling, cracking and popping of wall liners.

Construction sites are noisy places. While this noise is often unavoidable, noiseinduced hearing loss is not. Sadly, many workers believe noise is just ‘part of the job’ and something to get used to.
Prolonged exposure to loud noise can cause permanent hearing loss – something no worker or anyone on site should be exposed to.
What is noise-induced hearing loss?
Noise-induced hearing loss can occur gradually over time, or it can be instantaneous if you’re exposed to a one-off very loud noise like a shotgun going off next to your ear.
You lose the ability to hear some frequencies of sound, and while you may be able to hear people talking, it becomes more difficult to understand what they’re saying.
The damage cannot be fixed. Once you lose the ability to hear noise at a certain frequency, it’s gone forever. How noisy is it out there?
Noise levels will also change depending on where you are. Outside, a worker will be exposed to a lower range of noise, while inside or in an enclosed situation, they’ll be exposed to the higher end.
In New Zealand, the ‘average’ exposure limit is 85 decibels averaged over an eight-hour period. You may be exposed to noise levels above this, but only if the time you are exposed to is reduced.
It’s important to also remember that noise doubles every three decibels. This means that a tool operating at 88 decibels is actually twice as loud as a tool operating at 85 decibels.
How can you manage the hazard on a busy construction site?
Where noise levels are over and above the recommended levels per person per day, this workplace hazard must be ideally eliminated. If it cannot be eliminated, it must be managed through reduction of and minimisation of exposure.
Getting it right from the beginning is essential – some ways of doing this include purchasing quieter equipment, and ensuring it is properly maintained.
Where there is a residual risk of noise employers have a duty to provide personal protective equipment and to manage the risk. You must consider hearing protection and reduction of exposure through distance and time reduction. Controls will include:
• Getting workers to use ear muffs or earplugs
• Setting up dedicated areas or times when noisy work is likely to happen, and keeping visitors and others away from the area
• Reducing the time exposure to noisy activities and tasks.
Just giving your employees some earplugs or earmuffs is not enough. They must fit properly—otherwise, they are useless.
Where do I find out more?
WorkSafe has a noise-in-construction factsheet on its website: www.worksafe.govt.nz
About 150,000 workplaces throughout New Zealand use hazardous substances and the risks they pose are often underestimated.
For example, common hazardous substances like commercial cleaning products, paints, adhesives, acids, bases and solvents can cause serious harm if not used safely. Not understanding the harm that can occur when working with hazardous substances is a serious problem with serious consequences.
Between 600 and 900 New Zealanders are estimated to die from work-related illness every year, many from exposure to hazardous substances.
Exposure to different hazardous substances affects people in different ways. Health effects can include personality changes, sleep disorders, memory loss, cancer, fertility problems and even death.
These serious health risks are why it’s so important to safely manage the hazardous
substances at your workplace and protect your health and the health of your workers and others.
What is a hazardous substance?
The term hazardous substance refers to any product or chemical that has properties that are explosive, flammable, oxidising, toxic, corrosive or toxic to the environment.
Explosive – explodes or causes explosion. Flammable – ignites easily and burns rapidly.
Oxidising – could be gaseous, solid or liquid and can cause or intensify fire and explosion.
Toxic – can harm people if it enters the body through contact, being inhaled or ingested. The effects can range from mild to life-threatening and can be immediate or long-term.
Corrosive – can cause severe skin burns and eye damage
Silica is a natural substance found in concrete, bricks, rocks, stone (including artificial or engineered stone found in composite kitchen benchtops), sand and clay.
RCS dust is created when materials containing silica are cut, ground, drilled, sanded, polished or otherwise disturbed. RCS particles are extremely small; they can’t always be seen with the naked eye.
Silicosis is a progressive and deadly disease that causes fibrosis of the lungs from the inhalation of respirable crystalline silica (RCS) dust.
How workers can be exposed to RCS dust
Workers in the following industries or who work with the following materials are most at risk of being exposed to RCS dust:
• Quarrying
• Roading
• Foundries
• Construction: concrete, stone, bricks, mortar, fibre cement products
• Manufacturing of concrete, bricks and tiles
• Kitchen benchtop manufacturing (natural and engineered stone), finishing and fitting
• Abrasive blasting
• Monumental masonry work
• Mining
• Concrete drilling, cutting, grinding, fettling, mixing, handling, dry shovelling, tunnelling.
Ensure dust-generating equipment has a dust collection system with a filtered air supply to isolate the worker from the dust.
Use alternative products (eg metallic shot, slag products or grit instead of sand for abrasive blasting). If you can’t eliminate risks, you must minimise them so far as is reasonably practicable.
To minimise exposure to RCS dust
Instead of using engineered stone, use materials with a lower silica content. Engineered stone has approximately 90 percent silica compared with natural stone like marble and limestone which have around two percent silica.
Dust control measures
Use physical barriers or computer numerical control (CNC) machines to isolate work areas or tasks that generate dust.
When purchasing equipment and machinery, look for dust control features and dust collection systems. For example, tools used for cutting, grinding or polishing concrete and masonry should provide water to the blade and/or be fitted with an on-tool extraction system.
Ensure dust-generating equipment has a dust collection system with a filtered air supply to isolate the worker from the dust.
Use an H-class HEPA-filtered vacuum cleaner in accordance with Standard AS60335-2-69. This includes when working at someone’s home (eg to fit a bench). Workers should not use the household vacuum cleaner to remove dust.
Seal dust waste bags and place them in the correct waste container.

Closing off just before the Matariki long weekend, the Roofing Association of New Zealand (RANZ) 30th Celebration 2024 Conference included some new elements that added to an amazing experience for many RANZ member representatives in attendance, and for all RANZ Members to be proud of.
Celebrating 30 Years of RANZ
Country Conference registration opened on the Monday evening poolside, with a Welcome to Country smoking and didgeridoo ceremony from local Kombumerri people.
This was followed by fantastic opening addresses from RANZ President, Jenny Maxwell, and RANZ Gold partner sponsor Steel & Tube’s Mike Budd, acknowledging 30 Years of RANZ championing the specialist trade of roofing, with achievements including the formal roofing qualification establishment and safety at heights legislation to name but a few; made possible thanks to the support of RANZ Members and Sponsors.
Networking Activities and Sea World Delight
The Wednesday activities day provided some unique opportunities for networking and relationship-building, strengthening the RANZ network for the benefit of supplier and installer members alike.
It also allowed some breathing space, enabling some to catch up on daily work remotely, minimising business disruptions.
The Sea World dinner on Tuesday provided an enchanting evening that many delegates
brought their families along to. Most headed home with a soft toy won under their arm and even some dancing under their belts.
I Am Hope Charity Auction - over $20,000 raised
Richie Barnett joined the conference and outlined the work of I Am Hope in his keynote speech. RANZ delegates showed up for the conference fundraisers including a raffle, golf competitions, and raising over $20k at the finale auction held at the COLORSTEEL® dinner.
It was a wonderful start to the charity partnership and contribution to the vital work of I Am Hope, RANZ team! This new charity partnership was introduced this year by RANZ president, Jenny Maxwell and her executive team, which has been warmly received by members.
RANZ 2024 Award Winners
The future of roofing seems bright with stars like RANZ Trainee of the Year, Joseph Fraser of Aspect Roofing. The top man gave a heartfelt thanks to his Aspect Roofing team for supporting the development of his roofing skills and career.
The RANZ Residential Roof of the Year was awarded to Architectural Metalformers for their ‘Beach House’ project, as well as winning runner-up for ‘Beach House Re-roof’.
The RANZ Commercial Roof of the Year went to Edwards and Hardy. Huge congratulations to all the winners and entrants - celebrating roofing excellence in our RANZ member network.
Here is the full award-winning line-up:
Proudly sponsored by Austinsure, the Training Company of the Year Award is of great significance, with RANZ members having long held that we need to train our way out of skills shortages.
Harkin Roofing not only have a track record of continuous improvement for apprentices, including workshop training sessions, and a commitment to upskilling their staff, they are doing so with their commercial roofing focus.
Runner-up:
Winner: Joseph Fraser, Aspect Roofing
Judge’s Comments: “Joseph shines with his strong emphasis on teamwork, leadership, and a keen willingness to both learn and lead, along with his unwavering commitment to excellence and continual improvement.”
Residential Roof of the Year
Highly commended: WL Waterproofing Company for Goodwood Heights, Auckland
The team implemented Viking Enviroclad TPO (Slate Grey) roofing material complemented by solar panels, providing our client with a sustainable and ecofriendly roofing solution. This project showcases our dedication to innovation and sustainability, with the addition of Ejot Mounting Bars for the solar panels.
Judge’s comments: “The use of the TPO membrane gives a visually pleasing flat roof, defining this house from the surrounding properties. Combining the use of the EJOT bars for the mounting of the solar panels avoids multiple penetrations through the main roof area, providing absolute weathertightness.”
Runner-up: Architectural Metalformers for Beach House Re-roof
This retreat originally featured cedar shingles, which required replacing them with a product that would stand the harsh coastal environment. It was re-roofed using tapered custom-made trays in 0.6mm
Copper with cross welts. These architectural features include a curved head and barge flashings that transcend functionality and are fluid in their design. Tapering panels for precision, the craftsmanship and structural finesse are a testament to our team’s ingenuity to deliver this challenging project.
Winner: Architectural Metalformers for Beach House
This sophisticated, concave, standing seam aluminium roof blends seamlessly with its surrounding landscape. Combining durability with aesthetic appeal, it is installed on a plywood substrate, ensuring lasting protection and structural integrity. The central internal gutter further enhances functionality, efficiently managing water run-off while maintaining a sleek appearance, in keeping with the attention to detail that this project required.
Judges’ comment: “A very smart roof with clever use of the of the standing seam metal to create a curve to an internal gutter.”
Highly commended:
With a large amount of intricate cladding to roofing junctions and architectural flashings, collaboration between GHR, Form Building and ASC Architects were pivotal in achieving both the aesthetic and practical brief on the project. The RoofLogic Ultratherm MSR system ensured that both the acoustic and R-value parameters were exceeded.
Judge’s comment: “A very complex installation for a school. By utilising a warm roof system the school will benefit from the long term performance with reduced energy usage and healthier environment.”
Runner-up: CS Roofing Canterbury for Rolleston Hope Presbyterian Church Judge’s comment: “The curvature of the building, combined with the complexity of having to tie the façade, facia and soffit, whilst maintaining the aesthetic appeal is a testament to the great level of care and detail that has been undertaken by the installers of this project.”
Winner: Edwards & Hardy Gisborne for De Lautour Medical Health Centre
A very complex installation for a school. By utilising a warm roof system the school will benefit from the long term performance with reduced energy usage and healthier environment.
The re-roofing of the De Lautour Centre, a commercial building housing six doctors and a chemist, presented unique challenges while maintaining its operations. To minimise disruptions, the roofing team executed the work in stages – from front to back.
Safety measures like ground spotters, isolation zones, and scrims were employed, especially on the building’s front. The original roof was short-run corrugated iron with welded iron dormers. It was replaced with corrugated trough section and style lines profiles with membrane internal gutters. This approach allowed for replacement without exposure to the elements and bypassed the lengthy turnaround of external roll-forming services.
Additionally, air conditioning units were temporarily decommissioned and later reinstated. Insulation was installed, where necessary, ensuring the building’s functionality and comfort were maintained throughout the project. The entire project was undertaken over four months to ensure minimal disruption to the business.
Judge’s comment: “The challenge that they had with the vertical spire, this is truly crafted to a very high standard, well done.”
