Superintendent Paula Rose says last year's record low road toll was the highlight of a 27-year policing career.
The national road policing manager yesterday announced she is retiring and is looking forward to a future out of the familiar blue uniform.
"I haven't really had any other job," she said. "I was a student before I joined the police so this is the one and only real job I've had."
Ms Rose, who was a finalist for the Herald's New Zealander of the Year accolade last year, has no job waiting for her and no immediate plans to look for work.
"I'm a great believer things happen for a reason and am open to opportunities but that will happen after some R and R."
