What's the job really like?

Antony East

Antony East

Refrigeration Technician

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."

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:

  • meat processing companies
  • cool stores
  • supermarkets and other retail food outlets
  • construction companies
