"I was pretty nervous and didn't think I had a chance because they sat me at the back and I thought 'oh well this isn't good, they must be trying to tell me something', but then all of a sudden my name flashed up on the screen and I was pretty amazed.
"The morning after the awards I got a text message from Rod Drury saying congratulations, so that was pretty cool."
He had to get up and walk through a strong crowd of 350 plumbers from around New Zealand to accept his title and trophy.
Geenty started working in the industry for a Napier company in 1997 while still at high school.
"At the end of the school holidays they asked me if I wanted to work as an apprentice for them, so I must have done something to impress them. So I started the apprenticeship in 1998 and I've been a plumber ever since."
With the recent housing boom and population increase, Geenty said there was no sign of work going down the drain.
"It's just taking off, I love my work because you face different situations everyday, you're always meeting new clients and I really enjoy building good relationships with them. I like the range of work we do as well, it's plumbing, drain laying and gas fitting as well."
