Police in the Auckland region had dealt with a high number of vehicle breakdowns
Four breakdowns had been reported on the southbound lanes of the Southern Motorway.
Meanwhile, traffic in Wellington reached a standstill this morning as people tried to head north out the city.
Inspector Marty Parker said traffic on SH1 had reached a choke point near Pukerua Bay where a double-laned road merged into a single lane.
"Drivers are on good behaviour so we can't complain," he said.
Traffic was flowing steadily in Christchurch with people traveling toward Wanaka
Inspector John Doherty said police had received calls from drivers complaining about caravans and heavier vehicles not pulling over.
"It's about being reasonable on the road, you have to expect delays during the Easter break but we will also be taking it seriously if traffic is backed up behind an overly slow vehicle that won't pull over," he said.
