Carlos Donnell-Brown talks about life as a gasfitter – 2.16 mins

Hi, my name's Carlos. I'm a gasfitter.
So my job as a gasfitter is to connect and supply gas to a property for
residential and commercial.
The main 2 gases we work with are natural gas and LPG
- they're both used in pretty similar settings,
just supplied at different pressures. One burns a bit hotter,
one burns a bit colder. Yeah, so a usual day for me.
I try to arrive by site between the hours of, yeah, 7 and 7.30 am.
I'm usually there for most of the day.
Sometimes I'll be going to 4 or 5 jobs in a day.
Sometimes I'll be on one job for the week. What made me become a gas fitter was
I was at school one day and then a careers day kind of came through,
they set up hanging out with a gas fitter for the day.
Then I managed to ask him for a job and he gave it to me and I've been with the
same company ever since. So we're just heading off to a client of ours just
across the road from our workshop. It's just a commercial kitchen. First up,
we're going to go check the working pressure of this gas appliance here.
It's a gas deep fryer.
Why we're checking the pressures today is if it's too low,
then your appliance isn't going to work properly, it's not going to heat properly.
On the other hand,
it can also be burning too hot and actually damage the components of the
appliance. We're looking at right now,
the burner pressure 0.98 is the preferred pressure.
So to be a Certifying Gasfitter,
you first need to get your national certificate by sitting your apprenticeship,
and then after that you set your registration exam and then you have to wait
another 2 years and that's when you become a Certifying Gasfitter. The great
thing about the apprenticeship is that the whole time you are getting paid to do
it. Knowing now I probably would've paid a bit more attention in math class and
things like that,
but all this stuff can easily be relearned on the courses we take. It's coming
out slightly higher than is suggested on the rating plate.
So how we adjust that to lower it,
adjust that in slightly to 0.98,
which is the ideal pressure for the appliance:
getting pretty close now. My favorite thing about my job is the
practical parts of it is where I thrive and where I'm on the tools doing the

What are the chances of getting a job?

Strong demand for plumbers, gasfitters and drainlayers

Opportunities for plumbers, gasfitters and drainlayers are good due to:

  • a lack of apprentices training in these areas
  • moderate growth in construction predicted to extend until at least the end of 2023, meaning more building work
  • the Government’s KiwiBuild programme, involving the building of quality affordable homes over the next decade
  • building work needed to upgrade leaky homes and earthquake-prone buildings.

The Christchurch post-earthquake rebuild is ongoing but most of the remaining work is in the non-residential (commercial) sector.

According to the Census, 12,444 plumbers, gasfitters and drainlayers worked in New Zealand in 2018.

Increase your chances of getting an apprenticeship

Many plumbing businesses are small and often busy so they can't always take on and train apprentices. You can increase your chances of getting a plumbing, gasfitting and drainlaying apprenticeship if you have:

  • a good attitude to work, good time management skills, and are willing to learn
  • completed a Gateway or pre-trade programme
  • experience in plumbing, gasfitting and drainlaying
  • a tertiary qualification but want to retrain in plumbing, gasfitting and drainlaying.

Plumbers and drainlayers in shortage 

Although over 8,000 people work as plumbers, gasfitters and drainlayers in New Zealand, there are not enough to meet demand.

As a result, plumber, drainlayer and roof plumber appear on Immigration New Zealand's construction and infrastructure skill shortage list. Roof plumber also appears on Immigration New Zealand's regional skill shortage list. This means the Government is actively encouraging skilled plumbers and drainlayers from overseas to work in New Zealand.

Most plumbers and gasfitters run their own business

About 90% of plumbers and gasfitters are self-employed or work for small companies with up to five employees.

However, only about half of drainlayers are self-employed. Others work for small to medium-sized businesses that employ between one and 20 staff.
