Two people have so far died on the roads this Labour Weekend.
A death on State Highway Two in the Tararua District on Friday night shattered the police's goal of a fatality-free holiday period.
A second person died in a crash on State Highway 93, east of Mataura in Southland, at midday on Saturday.
National Road Policing Manager, Superintendent Paula Rose, says the speed limit tolerance has been reduced from 10 to four kilometres for this holiday period.
She says that was first done during Queen's Birthday Weekend, when there was one road death, and the police were hoping for an even better result this time.
Superintendent Rose says the lowest toll for a Labour Weekend since the 1950s has been three, which has been achieved on a number of occasions.
But she says there have also been much higher tolls during Labour Weekend.
Superintendent Rose says there were eight road deaths during Labour Weekend last year.
