But these days he works more behind the scenes, driving search and rescue operations mainly for missing trampers, dementia patients, and children, in and around Wellington.
"I am more into the thinking game around where to put people and where to use people."
It is his long service for Land Search and Rescue, as well as other volunteering roles, that earned Mr Stevens a nomination in the Pride of New Zealand Awards.
He was the regional winner in the Emergency Services section for the lower North Island.
Mr Stevens, 49, a senior analyst at the Treasury in Wellington, also volunteers as a paramedic at the Wellington Free Ambulance, doing a regular Friday night shift.
"You can really make a difference, when someone is dying you can actually help turn that around and that is quite an achievement."
He says his volunteer work helps him do his day job.
Mr Stevens, a father of three, has also helped instigate a programme that sees Treasury staff help with reading at a low decile school in Cannons Creek, once a week.
