Over the holiday period - between 4pm today and 6am on January 7 - anyone travelling more than 4kmh over the speed limit will be ticketed.
National manager for road policing Superintendent Steve Greally is urging New Zealanders to slow down this summer and said "less speed does mean less harm".
"I've seen first-hand the impact of speed in a crash, a 10kmh difference could save your life," he said.
"This is one of those messages some people don't like hearing, and some refuse to take on board. I just don't understand it.
"It's basic physics, it makes sense; the faster you crash into something, the more impact there will be."
In the year until December 19, 361 people have died on New Zealand roads compared with 363 deaths last year.
The road toll jumped by more than 50 deaths last year compared with 2016, when 310 people died.
Greally said we had all heard the old adage "it's better to arrive there late than not arrive at all", but it needed to be reiterated.
"We all want to go on holiday, we all have people we want to see, so let's all do our best to drive safely and watch our speed," he said.
"We want everyone to get where they're going safely."

If the cops cared the road toll would not be so high . All it is is a revenue collecting of the motorist that is already being held hostage by the Government petrol stations and the police writing ticket .
