The official holiday driving period has finished this morning, with 18 people dying on New Zealand's roads.
The period ran from 4pm December 23 to 6am this morning.
During the same period last year 12 people were killed, while in 2009/10 13 people died.
Transport Minister Gerry Brownlee said the toll was a "disappointing result".
"Every fatality and serious injury is a tragedy for the families and loved ones of those involved," Mr Brownlee said.
