The latest climate projections
What might New Zealand’s temperature, wind and rainfall levels look like over the rest of this century?
Using information on Aotearoa’s unique landscape and climate conditions, alongside global data and science, the National Institute of Water and Atmospheric Research (NIWA) recently developed its projections to show how the climate could change over the next 76 years. For the first time, this has been made publicly available by the Ministry for the Environment through the government’s Climate Data Initiative, with funding from the Ministry for Business, Innovation and Employment.
“Making these projections available means everyone can access the data and understand what climate change might mean for their community. This is an important step in improving access to climate information,” says Natasha Lewis, Deputy Secretary of Strategy Stewardship and Performance.
The projected changes to our climate
To determine how temperatures, rainfall, drought and wind might change over the rest of the century, the projections are based on Shared Socio-economic Pathway (SSP) scenarios developed by the Intergovernmental Panel on Climate Change (IPCC).
Temperature
Our country experienced its second warmest year on record in 2023, just shy of the record set in 2022, with an average temperature of 13.6ºC. Climate change
projections for Aotearoa show further warming is projected by 2090, with more hot days and fewer cold days across the country over the next decades. By 2090, annual average temperatures across the country are projected to increase by 0.8ºC in SSP1-2.6, by 1.9ºC in SSP2-4.5, and by 3.0ºC in SSP3-7.0.
Rainfall
More very rainy days – where daily rainfall exceeds 25 mm – are expected for many regions, especially in the Westland District which is projected to experience between three and five more very rainy days on average by 2090. However, the Gisborne District is projected to experience up to two fewer very rainy days on average by 2090.
Drought
Drought exposure is projected to increase over the east and decrease in the west of the North and South Islands. For example, the Kaikōura District is projected to experience an increase in drought exposure by 2090.
Wind
There are projected to be fewer windy days – with maximum wind speed more than 10 metres per second – per year for much of the North Island, and more windy days per year in most of the South Island by 2090.
A new design and construction project for Piersons
Meadow Mushrooms’ production facility has benefited from Piersons’ expertise in the design and installation of new heating and cooling equipment
Located in Hornby on the edge of Christchurch, Meadow Mushroom’s production facility is where most mushrooms sold in New Zealand are grown. The site is split into two shelf farms and one packaging facility, with the work by Piersons Refrigeration & Air Conditioning focused on Shelf Farm 1.
“Shelf Farm 1, over the past few years, has been suffering from reliability issues and high power consumption, leading to the overall running cost of the farm being far higher than desired. With the previous setup, the cooling and heating for the farm were delivered by three 750-kilowatt chillers, two of which were heat-reclaimed units capable of supplying low-temperature hot water. The chilled and heating primary and secondary water loops were also serviced via fixed-speed hydraulic pumps, further adding to the inefficiency of the plant,” says Matthew Thomas, Managing Director of Piersons Refrigeration & Air Conditioning.
“The most notable issue and root cause of the main problems experienced on site was the use of the heat reclaimed chillers as the main source of heating. As the site has inherent varying heat load conditions due to the mushroom growing process, this causes a large imbalance between the heating and cooling demands.
“This is especially important when we have a simultaneous heating and cooling requirement.”
Due to the limited knowledge of how exactly the farm behaved from a thermal standpoint, the Piersons team suggested staging the design and installation, allowing calculations to be performed.
With the aim of the project to enhance efficiency and reliability, and reduce the carbon footprint of Shelf Farm 1, the solution included:
• Replacing all primary and secondary pumps with VSD-driven units to enable the control of water flow. This also included the installation of various measuring stations for data collection.
• Replacing two of the existing chillers with two 750-kilowatt Daikin screw chillers.
• Replacing the third chiller with a high-efficiency 690-kilowatt smart magnetic centrifugal chiller.
• Installing two 200-kilowatt water source Daikin digital screw heat pumps for the low-temperature heating requirements.
The main areas of efficiency gains are thanks to the configuration of the heat pumps and the selection of the smart chiller.
“The smart chiller has been installed for its outstanding efficiency and low load conditions,” says Matthew, with COPs of 26+ being seen.
“On the heating side, we have used the chilled water return as our heat source for the heat pumps, essentially meaning we are recovering a portion of the energy absorbed via the chillers that would otherwise be rejected to the atmosphere and reusing it for our heating. As Meadow Mushrooms are highly motivated with regard to reducing the CO2 emissions of their operation, all three chillers and both heat pumps operate on the very low GWP refrigerant R1234ze, which has a global warming potential of just seven. By contrast, the old units operate on R134, which has a global warming potential of 1430.”
Piersons Refrigeration & Air Conditioning has delivered an impressive design that has exceeded expectations, with the production plant already seeing power savings in excess of $10,000 a month.

HVAC&R SYSTEMS - THE CONSEQUENCES OF CYCLONES
What risks do cyclones pose to HVAC&R equipment?
Weather events such as flooding and cyclones pose significant risks to HVAC&R equipment in homes and businesses
The Climate Controls Companies Association New Zealand (CCCANZ) advises homes and businesses to take important safety measures regarding heating and cooling systems when cyclones and severe flooding impact New Zealand. Buildings exposed to flooding and water damage can affect heaters, furnaces, boilers, air-conditioning, ventilation, heat pumps and refrigeration systems, putting people at risk.
Many people may not understand the need to replace flood-damaged air conditioning, heating and refrigeration equipment – they believe that their system has dried out and is once again fully operational, however, damage is not always going to be apparent. CCCANZ advises people to play it safe and replace, rather than repair flood-damaged heating, cooling and water heating equipment.
HVAC&R equipment affected by standing water will
typically be damaged beyond cost-effective repair, with fully submerged equipment requiring the replacement of all exposed electrical components and motors. There are also potential health issues like mould and disease caused by contaminated floodwaters.
If there is any question that flood water has reached heating and cooling systems, including domestic appliances such as heat pumps and refrigerators or freezers, equipment should be checked by a qualified professional. If you are concerned about receiving the right advice, look for a company that is a member of the CCCANZ and whose people are accredited through the Institute of Refrigeration, Heating and Air Conditioning Engineers (IRHACE). This is particularly important for commercial and industrial businesses where mould issues may not be apparent and thorough cleaning and inspection are required.
A sustainable, digital future
Companies have recently attended Chillventa, an international gathering of refrigeration, air conditioning, ventilation and heat pump experts
A comprehensive overview of refrigeration and insulation technologies, C&I and automation, air conditioning, ventilation and heat pumps, Chillventa is held each year as a place of in-depth professional dialogue and knowledge transfer. The three-day event, held on October 8-10 in Nuremberg, Germany, played host to presentations by experts, guided tours and special presentations. One of the topical issues highlighted at the show fair was digitalisation.
CAREL Group, parent company of Eurotec, was on the ground sharing its expertise in developing technologies that ensure energy efficiency and emission reduction are key elements in responding to recent regulations and contributing to the necessary decarbonation of the HVAC&R sector.
“The adoption of natural refrigerants is crucial for achieving global climate goals; therefore, CAREL has developed technologies that optimise their use, ensuring high performance in both industrial and residential settings,” shared CAREL Group in a recent media release.
At the event, the Group presented cutting-edge solution for sustainable cold chain management, components for
heat pumps in compliance with new F-GAS regulations, and solutions for high-temperature heat pumps and process chillers that facilitate industrial decarbonisation through the adoption of low environmental impact refrigerants. Artificial intelligence (AI) technologies were also showcased.
“Digitalisation not only enhances performance but also significantly simplified interaction with systems, making monitoring and remote maintenance easier. This approach significantly reduces learning times and facilitates anomaly diagnosis, allowing installers to save valuable time. Finally, continuous support provided by centralised control solutions facilitates integrated management and performance improvement of retail outlets, reducing inefficiencies and increasing sustainability.”
At Chillventa, as part of the Specialist Forums, CAREL conducted seven sessions covering a wide range of topics – from sustainable responses and the need for efficient food storage systems, to advanced solutions for temperature and humidity control and the crucial topic of connectivity.

Priority plans for WorkSafe
WorkSafe’s strategy for the next two years has been revealed with its priority plans published
The plans cover the sectors with the highest work-related harm in New Zealand – construction, manufacturing, forestry and agriculture – and enforcement, engagement and permitting activities will be delivered by WorkSafe across the priority areas to maximise its influence and achieve better, more equitable outcomes.
According to WorkSafe, its refreshed strategy defines the wider health and safety at work system (te aronga matua) and reflects it role in the system (kawa), how it will undertake that role (tikanga), where it will focus its effort (kaupapa), and how its impact (mātauranga) will be measured. The strategy acknowledges WorkSafe cannot be everywhere and emphasises the importance of collaboration.
“Workplaces in Aotearoa New Zealand should be healthy and safe. No one should be harmed or killed because of work. This is far from our reality. Every year 50-60 people are killed at work and 400-500 hospitalised with a serious work-related injury (acute harm), and an estimated 750900 people die because of work-related ill health (chronic harm). While these awful figures have steadily reduced over time, there is a long way to go and much work to do by everyone who can influence health and safety in our workplaces,” Jennifer Kerr, Chair, WorkSafe
“The law that underpins our work health and safety system places the responsibility for managing risks, and ensuring work is healthy and safe, on businesses with the support and involvement from their workers. This responsibility is based on the fact businesses and workers best know their workplace, they best know their risks, and they best know how to manage them.
“As the primary health and safety at work regulator, WorkSafe’s role is to influence businesses to carry out their responsibilities – and to hold them to account if they don’t.
“While WorkSafe has a significant role in influencing better outcomes, it cannot do this alone. Other government agencies, industry bodies, iwi, and unions all have a vital role to play.”

Case study: new HVAC for a Tauranga retirement village
All Seasons Air Conditioning has delivered an optimised HVAC solution to the Pacific Coast Retirement Village’s new Care Centre facility, Te Manaaki, using Daikin technology
The unveiling of The Care Centre - Te Manaaki took place in June 2023, marking a seamless extension of Pacific Coast Retirement Village. The necessary objectives for the air conditioning system included robustness, energy efficiency and the capability for simultaneous cooling and heating, as well as centralised control with scheduling and general monitoring functions. Outdoor units were required to have a compact footprint, strategically positioned on the roof, while indoor units were to remain discreetly concealed within communal spaces and care suits, ultimately ensuring a comfortable environment for residents.
Originally designed with nine REYQ-TAY1 VRV Heat Recovery outdoor units, the solution was optimised by transitioning to the newer REYQ-BYM range. This change not only enhanced efficiency but also reduced the number of outdoor units to seven, achieved by utilising two 24HP single module condensers. The compact design of the outdoor units facilitated easy installation within the limited plant room space on the roof. The new 24HP condenser utilised 7 per cent less installation space (1.34sqm) and weighed 11 per cent less (409kg) compared to its predecessor.
To contribute to cost savings and minimise on-site work, the majority of the multi branch selector (BS) boxes selected were the new drainless BS boxes. These were strategically located in the ground floor corridor and attic space for easy accessibility for future service and maintenance.
Considering the diverse spaces and their unique air conditioning and aesthetic requirements, a wide range of VRV indoors were selected for the project. For example, Bulkhead FXDQ-SPV1 units seamlessly integrated into the drop ceiling at the care suites entrances with their slim 200mm height profile.
Mid to high static ducted FXMQ-PAVE units were strategically placed in the ceiling spaces of lounges and corridor areas, complemented by remote temperature sensors BRCS01A-5 for accurate return temperature readings. A round flow cassette with sensing FXFSQ-AVM provided comfort in the lunchroom with its extensive range of airflow patterns and individual airflow direction control for each air discharge outlet. The compact cassette FXZQ-AVM integrated seamlessly in the standard architectural ceiling tile of the ground floor office with
its elegant fully flat panel design. Additionally, a hi-wall FXAQ-AVM unit was utilised in the small meeting room on the same level. A separate commercial hi-wall system was needed for the laundry room, the FTXC-AV1 system accommodated a piping length of up to 75m between the indoor and outdoor unit.
The DEC102 adaptor card was incorporated to integrate ventilation systems and establish a fire interlock.
To enhance resident convenience and comfort, BRC1E63 wall-mounted controllers were selected for the care suites. These controllers, equipped with a built-in temperature sensor and user-friendly functions, provided residents with control over temperature, mode changes, airflow rates, scheduling, and an off timer.
The Care Centre - Te Manaaki serves as a great illustration of the effective integration of the latest Daikin VRV product into a retirement village project, meeting all the customer’s specifications. The precise installation by All Seasons Air Conditioning was carried out in close collaboration with the builder and other on-site contractors, ensuring a timely project delivery. The facility welcomed its residents in the third quarter of 2023.

Shaping the future of HVAC&R
ARBS, Australia’s leading HVAC&R and building services exhibition, recently released its new whitepaper, Catalysts for Change:
Learnings from ARBS 2024
Developed by ARBS Chair, Professor Tony Arnel, the whitepaper captures the strategies and insights that emerged from ARBS 2024 – an event that Gina McMaster, HVAC&R Centre Executive Office, described as emphasising the industry’s “ongoing commitment to innovation and excellence”.
The whitepaper discusses the critical role of HVAC&R in advancing global sustainability efforts by addressing key themes including electrification, smart systems, and circular economy practices. It highlights the increasing significance of embodied carbon, which is expected to account for up to 85 per cent of the built environment’s emissions by 2050.
“Building services operate quietly in the background, invisible to the everyday observer. Yet, they are at the epicentre of some of the world’s most visible and pressing issues,” says Professor Arnel. “From managing indoor air quality to reducing energy consumption, cutting carbon emissions to championing a circular economy, HVAC&R is at the heart of a healthier, more sustainable future.
“Our visitors came for the exhibition and networking and stayed for the seminars – 45 in total – that explored a multitude of topics and gave a diverse range of professionals a thought leadership platform. From the concepts covered in the seminars, and from the conversations held with customers and competitors on the exhibition floor, we know two topics are at the forefront: carbon and circularity. While it’s impossible to capture every idea shared at ARBS 2024, we’ve distilled the discussions and debates into a ready reckoner for HVAC&R leaders looking into the future.”
Insights from the whitepaper
include:
• Priority on electrification: Calls the industry to prioritise electrification to support decarbonisation efforts. It highlights the need for more efficient and smarter systems to meet the demands of a rapidly warming world.
• Focus on embodied carbon: With embodied carbon poised to become a dominant factor in building emissions, the whitepaper urges industry leaders to measure and manage these emissions now, using tools like the NABERS Embodied Carbon Tool.
• Adapting to regulatory shifts: Outlines how upcoming regulatory changes, including Australia’s national net zero targets and the Global Cooling Pledge, will impact the industry. It provides a roadmap for aligning business strategies with these new standards.
• Innovation through circular economy: Advocates for a shift towards circular economy principles, encouraging HVAC&R professionals to rethink design and material use to extend the lifecycle of products and reduce waste.
“Our industry stands at a pivotal moment and our actions today will determine how effectively we can reduce emissions and create a sustainable future.”

An inside look at Cold Hard
The highly anticipated report has been released, highlighting key developments the refrigeration and air conditioning industry
Now in its 19th year, the Cold Hard Facts series delves into the country’s HVAC&R sector, providing a broad overview of where the industry currently stands, alongside invaluable data including the stock of equipment and the total available in the refrigerant bank.
Cold Hard Facts 4 presents data from 2022, with previous major updates seen in 2018, 2013 and 2007. Partial updates were published in 2022, 2021, 2020 and 2019.
Each report intends to assist policymakers and the industry with the management of synthetic greenhouse gases, including hydrofluorocarbons, and the management of ozone-depleting substances as they are phased out.
A growing industry
This latest report highlights Australia’s growth across all classes of equipment and services in the sector.
In particular, the stock of vapour compression-driven equipment that provides refrigeration, cooling, heating, comfort and utility services grew by around 15 per cent in the six years from 2016 to 2022 (the latest data this report is based on), reaching a total of more than 62 million pieces of equipment. According to the report, 2022 saw an increase of about 1.6 per cent on the previous year of the total bank of refrigerant gas employed across the stock of equipment – reaching an estimated 55,000 metric tonnes.
Environmental impact
However, this growth has an impact on the environment. According to the report, “This stock of equipment is estimated to have consumed 24 per cent of all the electricity produced in the country in 2022. This makes vapour compression systems one of the largest users of electricity in Australia.”
This translated to contributing to approximately 12 per cent of Australia’s total greenhouse gas emissions. Of this, about 87 per cent was attributed to indirect emissions, and 13 per cent to direct refrigerant emissions. The report notes that the direct emissions of refrigerants will rise as the grid goes through the process of decarbonising. “The decarbonisation of the Australian grid electricity generation is well underway with the average emissions intensity of grid electricity in Australia dropped by approximately 20 per cent from 2016 to 2022 (0.91 kg CO2e/kWh in 2016 versus 0.73 kg CO2e/kWh in 2022, (DCCEEW 2023b), a trend that is expected to accelerate.”
Refrigerant lost
Cold Hard Facts 4 states that the sum of direct HFC refrigerant emissions and EOL HFC emissions in 2022 was calculated to be equivalent to just over 10.6 Mt CO2e. Total recoveries of refrigerants for destruction, from EOL equipment or during servicing of working equipment, was 463 tonnes.

“Recoveries that were reclaimed for reuse was about 100 tonnes in the year, with changes to the stock of equipment effectively seeing off the period when it was economic to recover and recondition hydrochlorofluorocarbon (HCFC), the older generation of refrigerants phased out under the Montreal Protocol. This generational change came about as the stock of HCFC-charged equipment declined rapidly as equipment was retired from use. Better management of this retiring stock of equipment represents a significant opportunity to avoid those emissions.”
The use of natural refrigerants
There has been a constant uptake of natural refrigerants. With the industry’s growth, and as the Kigali Amendment’s HFC phase-down progresses, the HVAC&R industry is expected to adopt more environmentally friendly refrigerants to meet regulatory requirements.

Cyber Smart Week is here
This Cyber Smart Week, we’re supporting the National Cyber Security Centre by encouraging you all to own your online. There are some simple prevention measures that we can all take to make life much harder for cyber criminals
The scary reality is that New Zealanders lose $198m to scams each year. Why? People assume they’d not be stupid enough to fall for an online attack, so many of us don’t take simple actions to protect ourselves. However, people aren’t foolish – they’re optimistic, busy, and eager to please. We’re all human, and our humanity is what can make us vulnerable to online attacks.
While these fraudsters play on our human nature, there are things every New Zealander can do to protect themselves online. But the National Cyber Security Centre’s latest results highlight that many of us don’t do them:
• 43 per cent use the same passwords for their online accounts
• 30 per cent admit to not using strong passwords for their main online accounts
• 32 per cent do not use two-factor authentication for their main online accounts
All of this leaves us vulnerable for scammers to prey on our innate kindness as a way into our hearts – and bank accounts. It is through this ‘generosity’ that we’re inadvertently ‘donating’ to scammers every year.
So, for this year’s Cyber Smart Week, NCSC is launching The Scamathon. The Scamathon shows scammers who are excitedly thanking us for our kind donation, a bit like the Telethon events from the 70s and 80s. It’s a way of showing us all how sometimes our kindness is preyed upon to get us reaching into our wallets for more sinister motives.
The campaign encourages people to avoid ‘donating’ to scammers by showing ways we can all help stop The Scamathon – in particular, by:
1. Having long, strong and unique passwords, and
2. Turning on two-factor authentication across your online accounts. Find out more about
Two key actions to help you own your online
Here are some easy steps you can do to help stay secure and in control of all your things online:
1.
2.
Create long, strong and unique passwords
Use a different password for each account and avoid using personal information, like your date of birth, in your password. Passphrases (random phrases of four or more words, for example, coffeecountsasameal or mapsshouldbesouthsideup) make for the best passwords. They’re easy to remember but hard for attackers to crack.
Turn on two-factor authentication (2FA)
2FA is an additional layer of security that helps to protect your online accounts. A common form of 2FA is a unique code sent to your phone or taken from an app that only you have access to.
You can use it to authenticate who you are every time you log in. That way, even if an attacker gets your login details, they still won’t get in. Start by setting up 2FA on your bank, email and social media accounts.
Other actions to protect yourself online
Activate auto updates on apps and devices
Updates aren’t just about getting the latest features available on apps and devices, they also protect you from any weaknesses or vulnerabilities that have recently been discovered and that could let attackers in. The easiest way to do this is by going to settings and turning on automatic updates.
Set your social media settings to private
Make sure your social media privacy settings are switched over to ‘Private’ or ‘Friends only’. This way, you can control who sees what information you share and who you’re sharing it with.
Think before you click
Be wary of opening links and attachments in text messages, emails or on social media. These can be used by attackers to get hold of your personal details or to install malware on your device. Even if you think the text might be legitimate, it’s better to go to the organisation’s website using another method. If something sounds too good to be true, it probably is!
Report it
If you, or someone you know, experiences an online security incident, report it to CERT NZ. They’re here to help New Zealanders protect and recover from online security threats and incidents. cert.govt.nz/report

Insight to a 60+ year career in HVAC&R
Records show that Alan Jaffe has been a member of IRHACE for 60 years, with the real number potentially higher than this… We asked Alan to share what his time in the industry has looked like
Words by Alan R Jaffe NZCE Refrig: LMIRHACE
I first wrote for the IRHACE Journal in December 2008 on how I came to be employed in the refrigeration industry. Extracts from that journal say: “My late father, Jack Jaffe, was a bespoke tailor who had served the well-respected Mr Maurice Paykel, a founding Director of Fisher & Paykel Ltd, and Mr Keith Doyle, General Manager of McAlpine Refrigeration Ltd. This relationship led to my Dad asking these men, ‘What am I going to do with my son Alan?’”
Soon after this question was asked, I recall walking into McAlpine’s Newmarket office and signing my apprenticeship papers. I have never looked back at that decision, and with great satisfaction achieve a well-fulfilled lifetime in the industry.
In 1953 when I started my apprenticeship at McAlpine Refrigeration, I was first employed at their Walls Road Penrose factory making air conditioning and commercial refrigeration systems for specialist environments like hospital operating theatres, telephone exchanges, manufacturing environments requiring humidity, temperature, and clean air conditions.
Running parallel to my time at the Penrose factory I attended Seddon Memorial Technical College and learned the fundamentals of heat exchange principals and such things as Boyle’s Law. Incidentally my tutors were senior management engineers employed by McAlpine Refrigeration.
After a few years at the factory, I moved to the service department where I soon learned to service domestic refrigerators manufactured by McAlpine and carrying the Prestcold label. Out in the field I found myself enduring the rigours of very toxic sulphur dioxide and methyl chloride refrigerants common to the early days of household refrigerators, and often came home with burning eyes and blistered skin on my hands!
A stint serving compulsory military training at Tihoi and Waiouru servicing high pressure compressors was a great experience.
So, there were many highlights experienced when working from 1957 to 1964 as a service technician for McAlpine in Newmarket attending to many systems I helped build at the Penrose factory.
For example, I was part of the industry where there were many office and shop air conditioning systems installed which were adapted from commercial refrigeration componentry. However a massive change occurred when companies like Temperzone, founded in 1956 by the late Eric Kendall, and McAlpine Refrigeration with Fred Needham started the production of Singer Incremental units, Fisher & Paykel and Frigrite.
It was 1962 when the late Jim Hawke introduced Worthington and later followed with iconic brand names like Zonepak and FPE, then Muller NZ Ltd when the late Brian Farmer introduced Seasonmaker. All these products were manufactured units using mass production methods and protected by rigours of strict import licensing.
One should note that McAlpine Refrigeration Ltd was an excellent communicator to their large number of employees and branches, with their publication of Sight Glass. This extract from October 1962:
“Application of Packaged Air Conditioning Equipment” refers to ‘split systems’ being air or water cooled where the latter was often applied running condenser water down the drain, and not through a cooling water tower!”
I have a 1964 record of an air conditioning installation for the Auckland Star building in Shortland Street. I was present when the Penrose-built water chillers were started for the first time… Unfortunately the pipe fitting contractors forgot to tighten the large diameter hoses carrying chilled water down to the air handling units and huge quantities of water severely damaged the huge rolls of newsprint and subsequently delayed the printing of Auckland Star.
McAlpine in the late 1950s imported window type air conditioning units, having brand names like Fedders ex USA and Tempair ex England. Tempair was a subsidiary of the Rootes Group, makers of Hillman and Humber cars who had, during WWII, turned into making tanks for the British Army and designing for military activities in hot climates, thus their development in air conditioning units.
Returning to New Zealand I worked in high-rise buildings using large chilled water air conditioning systems using R-11 refrigerant.
The ductwork systems were designed with dual ducts where hot and chilled air was sent to mixing boxes and then into extensive ductwork. Also common was the installation of perimeter type high-pressure induction units, and low-pressure centre zone ductwork.
The establishment of Temperzone as a significant manufacturer for finned coils, air handling units and associated components is well documented. They were supplemented by other manufacturers producing products with brand names such as Bonaire, Carrier, Cooke, Muller, Remington, York and Zonepak.
Specialist manufacturers and suppliers supported the rapid growth of the air conditioning industry included, Fantech, GEC, Holyoake, Honeywell, Staefa and numerous sheet metal/ductwork factories.
Running parallel to the growth of HVAC were long-established companies active throughout New Zealand designing, installing and maintaining industrial refrigeration equipment into massive freezing works using ammonia refrigerant, associated large cool room evaporators and cooling towers.Oldies will recall names like Sabroe, Hall, Sterne, York, Mycom, and many more!
During these times there were many young boys taking up apprenticeships who later became very successful people in the HVAC&R industry.
Legionnaires disease was not heard of during those formative years – now widely known to be a result of inadequate maintenance procedures associated with water cooling towers in large air conditioning systems.
There was also extensive use of asbestos-type insulation wrapped around chilled and hot water pipework. It was an effective insulation, but a silent killer to many who worked in the HVAC industry – I lost two very experienced engineers from asbestosis.
I witnessed the dropping of a large centrifugal chiller onto the footpath from the top floor of a high-rise building in Shortland Street, Auckland, and in today’s parlance, it was ‘munted’.
Fisher & Paykel Engineering Ltd took advantage of the NAFTA agreement during the mid-70s where refrigerators and washing machines were exported in exchange for the importation of Australian-made products. This included window-type room air conditioners and office water coolers all manufactured in Adelaide Australia by Kelvinator and marketed under well-known brand names – ZonePak, Kelvinator, McAlpine and Supercool. Prior to the importation of these units, some were manufactured in small volumes by Fisher & Paykel in their Mt Wellington factory.
The major air conditioning contractors had for many years huge backlogs of work, since high rise office buildings were being built for entrepreneurial developers, government departments, insurance companies, banks, and public and private hospitals.
Prominent were Fletcher Mechanical Ltd, Fisher & Paykel Frigrite (later Fisher & Paykel Engineering Ltd), A & T Burt Ltd, Cooke Heating Ltd, Chenery Ltd, Aqua Heat, Deep Freeze Projects Ltd and Wilkins & Davies Ltd, and many more, some of which merged into other companies and others lost to the vagaries of underestimating, bad management, recessions, and builders going into receivership.
One must not overlook the growth of specialist consulting engineers, quantity surveyors and their related architects who prospered with the rapid growth and acceptance of

Latest scams and alerts
Westpac have on their website the latest scams and alerts, https://www.westpac.co.nz/personal/ways-to-bank/safety-and-security/latest-scams/
Brushing scams
What’s happening?
Have you received an unexpected parcel in the post, generally containing a low-value item and a QR code? Be cautious and make sure that you don’t fall victim to the latest scam to affect New Zealanders – ‘brushing’.
Brushing scams involve offenders sending out parcels containing unsolicited, often low-value items with no (or limited) information on the sender; alongside the item will also be a QR code.
Offenders are relying on the lack of information contained within the parcel to encourage recipients to scan the QR codes to learn more about the package and sender. Instead, once the QR code is scanned the recipient is at risk, with the QR code generally directing them to a website that will attempt to compromise their personal and financial information through either phishing or malware.
Westpac is aware that some New Zealanders have received ‘brushing’ parcels, and urge you to be cautious with any unsolicited parcels, and unsolicited communication more broadly.
What should I do?
• If you receive an unsolicited package similar to what is described above:
• Don’t scan the QR code included in the package;
• Don’t try and find the sender’s website;
• If you have scanned the QR code, contact your bank immediately;
• If you think your personal details have been compromised, you can also contact ID Care on 0800 121 068 or 09 884 4440, 10am to 7pm, Monday to Friday.
New Zealand Police advises that you can either keep or dispose of the unsolicited item.
