Drivers are urged to drive to the conditions during winter after car crashes over the long weekend killed 11 people, the worst Queen's Birthday Weekend road toll in 27 years.
The New Zealand Transport Agency has launched its Winter Journeys campaign, which encouraged drivers to plan ahead to reduce winter driving risks.
"There are more vehicle crashes during June and August when motorists are likely to encounter fewer daylight hours and wetter, more slippery roads," NZ Transport Agency Auckland and Northland director and road safety director Ernst Zollner said.
"The room for mistakes is reduced when road and weather conditions are less favourable, and we don't want anyone's mistake to end in an avoidable tragedy."
He advised drivers to allow more time for travel, slow down, being prepared for unexpected hazards and allow greater following distance.
Advice for drivers
• Slow down and watch your following distances. It only takes a split second to lose control on a wet road.
• Maintain a four-second following distance between you and the vehicle in front of you.
• Plan your journey, check weather and road conditions and choose the safest route. If possible avoid travelling in extreme weather and road conditions.
•Observe road closures and restrictions.
