What's the job really like?
Get ahead with a can-do attitude
"I'd been doing carpet laying and some trade experience can be helpful for getting into this job, but it’s more about having good communications skills and the right attitude," says building insulator Kale Charteris.
The right attitude has earned Kale a team leader role after only 18 months in the job.
“You’ve got to be keen to work in underfloor and ceiling spaces, which are often dirty, and be flexible enough to get into tight spaces."
Earn more if you’re careful and quick
"When I started I got put into different teams to see how others worked. The quicker and better you get the more you can earn, and there’s no shortage of work.
“The job’s got to be up to standard and everything done to government regulations. The biggest challenge is making sure when you’re up in the ceiling you don’t knock any electrical downlights or HRV systems.”
A steady role with good training opportunities
“Getting a building insulator job was a massive step up for me. I had the security of a full-time role.”
Kale is optimistic about his future and says his company offers training opportunities. "There are sales roles and auditing roles, but I’m also keen on becoming a insulation contractor."
Kale Charteris is of Ngā Puhi descent.
There are no specific requirements to become a building insulator as you gain skills on the job.
However, most employers prefer you to:
- have a driver's licence
- pass a drug test
- agree to a pre-employment police check.
Bigger companies usually run their own internal training programmes. The Insulation Association of New Zealand (IAONZ) runs a training programme for building insulators involving
on-the-job training and theory.
No specific secondary education is required for this job, but construction and mechanical technologies, and maths to at least NCEA Level 2 are useful.
Year 11 and 12 learners can find out more about the construction industry, and gain relevant skills, by doing a National Certificate in Building, Construction and Allied Trades (Level 1 and 2) through the BConstructive programme.
For Year 11 to 13 learners, trades academies and the STAR and Gateway programmes are good ways to gain relevant experience and skills.
Building insulators need to be:
- able to use their initiative and display good judgement
- able to work well with others
- good at problem solving
- accurate and able to do basic maths.
Useful experience for building insulators includes:
- building industry work such as carpentry
- general construction or building labouring work.
Building insulators need to be fit, healthy and strong as the work involves climbing and lifting. They also need to be able to work in confined spaces and at heights.

What are the chances of getting a job?
Insulation subsidies and construction growth mean good demand for building insulators
Building insulators are in high demand due to:
- the Warmer Kiwi Homes scheme, which funds subsidised insulation for New Zealanders on low incomes
- the Government's Healthy Homes standards, requiring all rental homes to meet new insulation standards by July 2021.
- moderate growth in construction predicted to extend until at least the end of 2023, meaning more building insulation work
- the Government’s KiwiBuild programme, involving the building of quality affordable homes over the next decade
However, like many building jobs, this role can be affected by economic conditions. A downturn in the economy can lower demand for building insulators.
According to the Census, 692 building insulators worked in New Zealand in 2018.
Insulation work often seasonal
Insulation work is mainly seasonal, with fewer opportunities during the colder months. However, the Government's Warmer Kiwi Homes scheme has increased demand for insulation work, and some larger companies employ building insulators for the whole year.
Increase your chances of getting hired
You can increase your chances of being hired as a building insulator if you have:
- a good attitude to work, good time management skills, and are willing to learn
- completed a Gateway or pre-trade programme
- the ability to use hand tools
- any trades experience.
Most building insulators work for private companies
Building insulators usually work for private insulation companies, which range from small businesses with only a few staff to ones that employ 100 people or more.
