Police still hope to keep the Easter road toll at zero, as people head home at the end of the long weekend.
If there are no fatalities before the official Easter road toll period ends at 6am on Tuesday, it would be the first time no one has died on the roads during a holiday period.
Police say roads around the country will be congested on Monday evening and motorists should expect delays.
Acting National Road Policing Manager, Acting Superintendent Rob Morgan, says all motorists are responsible for driving to the conditions and following the road rules.
A four kilometre per hour speed limit tolerance is in place until 6am on Tuesday.
Mr Morgan says there will be a lot of traffic in and out of big cities like Auckland and Wellington, as well as on the highways.
He says people need to plan their journeys and allow extra time.
The lowest holiday road toll recorded is one, which has been achieved twice - once at Queen's Birthday in 2010 and once more than 50 years ago.
The lowest toll for an Easter period is three, recorded in 1998, 2002 and 2003.
