Plumbing not all dirt and muck

"A lot of people think plumbing is all blocked toilets, but the whole time I've been doing my apprenticeship I've only had to unblock two or three, so it's not all dirt and muck," says plumber Josh Boyce.

"Most of the time you're working on putting pipes in new houses, renovating older houses or working on commercial job sites, which is actually pretty clean work."

Working with copper pipes a favourite part of the job

While Josh can't name a part of the job he dislikes, he does have some favourites. "I love working with copper pipes, doing the brazing and welding with copper. That's when you heat it so it melts to join two pieces together. When you take pride in your work it really shows with copper. It's almost a shame to cover up the walls!"

As for the future, Josh is looking to work overseas. "One of the best things about a plumbing and gasfitting apprenticeship is that plumbers and gasfitters are needed everywhere, not just all over New Zealand. I can see the world and earn money while I'm doing it."

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
  • a construction boom that is predicted to continue until at least the end of 2020, meaning more building work, which requires plumbing
  • the post-earthquake rebuild of Christchurch
  • building work needed to upgrade leaky homes and earthquake-prone buildings.

Increase your chances of getting an apprenticeship

Because many plumbing businesses are small and/or very busy, they are not always able to take on and train apprentices. You can increase your chances of getting an apprenticeship by:

  • being proactive and contacting possible employers
  • dressing smartly and showing you are keen when you visit employers
  • volunteering to work with a company to understand what the job involves, or asking a plumber if you can shadow them (spend a work day with them), to see exactly what they do.

Although completing a pre-trade course such as Gateway and BConstructive through school, or later through a tertiary provider can show you are keen, it is not essential and it will not shorten your apprenticeship. 

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 immediate 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.
