Plumber video

Ben talks about life as a plumber - 1.11 mins. (Video courtesy of Got a Trade? Got it Made!)

So when I decided to start my apprenticeship, it was from day one I knew I made the right choice. Day one was basically get in there, start working with another guy and learn from there.

Being hands-on has massive appeal for what I looked for in a job. I meet 10 different people every day and I work with sparkies, electricians, builders. You’re never stuck on the same job, I might be redoing this kitchen today and then tomorrow I’m working on a commercial boiler unit. We just go out and solve problems and we come up with solutions, and it takes a bit to get there but once you’re there there’s so many options.

I definitely feel a few steps ahead of my peers. I know I have a lot of people who look at me and see, “Oh look, he’s got the house, he’s got the car, he’s all sorted, ready to rock 'n' roll”, and that’s just the way it is when you’re earning and learning.

My name’s Ben, I’ve got a trade and I’ve got it made.

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.
