"It's like a big family here - everyone looks after each other. And the management and health and safety here is absolutely top notch. I've been treated very, very well."
In more than four decades on the job, Mr Massey has seen plenty of changes in the fire service. In particular, the type of work firefighters do has changed.
"We attend a lot more motor vehicle accidents now, and we're often the first responders for medical events. I'd say around 40 to 50 per cent of our work now is medical.
"Firefighting is still obviously very important, but it has taken more of a back seat now."
Mr Massey has never turned his back on cars. Until 1993 he worked for a mechanic on his days off; now he has his own workshop at home.
"It will be nice to spend more time there. I also love fishing - I go fishing off the Whanganui coast and do trout fishing in Taupo.
"I have plenty to do in my retirement."
That's if he is able to retire: Mr Massey has already been offered several mechanics' jobs, but he's turned them down.
"I don't think I'm ready for another job just yet."
