What's the job really like?
After taking on a job as a labourer at a refrigeration company and discovering he had "a bit of mechanical aptitude", Antony East decided to follow it up with an apprenticeship in refrigeration.
"It's a challenging job and really enjoyable. The range of refrigeration systems is amazing. You can work in apartments, supermarkets or on container ships – the possibilities are endless."
"It's always different"
"It's a real challenge fixing faults because there are always so many possible options. Doing maintenance all the time comes in handy because you get to learn how to repair different problems pretty quickly."
Variety is the key for Antony, who says he never knows what he will be doing next. "I can be working in a chiller or on a roof – it's always different. The principles are all the same at the end of the day, but you're forever working in a different place on a different fault."
Lots of opportunity
"It's one of those trades where you really feel in control of your destiny. You've got the ability to advance in so many different directions, whether it's a sideways direction within refrigeration or getting into management or going overseas. It's a very interesting job."
There are no specific entry requirements to become a refrigeration/air-conditioning technician.
To become a fully qualified refrigeration/air-conditioning technician you need to complete an apprenticeship and gain a New Zealand Certificate in Refrigeration and Air Conditioning –Trade (Level 4). The industry training organisation Competenz oversees refrigeration/air-conditioning apprenticeships.
Employers usually prefer refrigeration/air-conditioning technicians to have a driver's licence.
No specific secondary education is required for this job, but maths, physics, digital technologies and English to at least NCEA Level 2 are useful.
For Year 11 to 13 learners, trades academies and the STAR and Gateway programmes are good ways to gain relevant experience and skills.
These programmes may help you gain an apprenticeship, but do not reduce the amount of time it takes to complete it.

- accurate and safety-conscious
- good communicators
- good at making calculations and problem solving
- able to work independently or in a team
- able to work well under pressure
- comfortable working in enclosed spaces and at heights.
Useful experience for refrigeration and air-conditioning technicians includes:
- plumbing and gasfitting
- work in an engineering workshop
- electrical work or experience in an engineering company.
Refrigeration/air-conditioning technicians need to have a good level of fitness and must be strong as they may need to carry heavy refrigeration/air-conditioning equipment.
Qualified refrigeration/air-conditioning technicians need to be registered and licensed with the Electrical Workers Registration Board.
To work with compressed gas you must hold an approved filler compliance certificate.

What are the chances of getting a job?
Refrigeration/air-conditioning technicians are in demand due to:
- the building boom
- increased demand from food suppliers, supermarkets and other chilled food retailers
- the aging workforce of refrigeration/air-conditioning technicians
- too few apprentices being trained to meet demand.
Air-conditioning and refrigeration mechanic appears on Immigration New Zealand’s construction and infrastructure skill shortage list. This means the Government is actively encouraging skilled refrigeration/air-conditioning technicians from overseas to work in New Zealand.
Your chances of securing an apprenticeship are best if you first take a pre-trade course, according to the Institute of Refrigeration, Heating and Air Conditioning Engineers.
Employers and clients varied
Most refrigeration/air-conditioning technicians are self-employed, or work for private companies specialising in the sale, design, installation and maintenance of refrigeration and air-conditioning systems. Their clients may include:
