The level 4 lockdown was enforced as of midnight March 25, and police have been out in force this Easter weekend at national highways checkpoints questioning motorists about their destinations.
Since March 26, much has been made of police powers and discretion when it comes to what people can and cannot do under the lockdown rules.
New Police Commissioner Andrew Coster - who marked a week in the top job yesterday - this week announced there would be checkpoints across the country over the long weekend.
The fear was that people would try to scarper to baches and holiday homes for an Easter "break".
Aside from the potential of spreading Covid-19 by travelling, there is the huge risk of crashes that would tie up already-stretched emergency services and hospital staff.
"We know many New Zealanders may have been planning to catch up with friends and family this weekend or travel to traditional holiday destinations but we urge anyone who was planning to do this - please change your plans and stay home," he said.
"To help ensure people know about the Health Act restrictions, police will be out and about checking that people are travelling for essential purposes only.
"It's simple - travelling to and from different towns and cities risks spreading Covid-19 and puts lives at risk."
As of today there were 1312 cases of Covid-19 in New Zealand.
Two more Covid-19 related deaths announced on Saturday brought the total death toll to four.
Director of public health Caroline McElnay reported 29 new casesand said 422 people with Covid-19 in New Zealand have now recovered.
Fifteen people are in hospital - five are in intensive care units and one patient in Dunedin is in a critical condition.
The latest two people to die of Covid-19 were elderly, had underlying health conditions and could be linked to existing clusters.
One was a man in his 80s who died at Wellington Public Hospital yesterday. He became unwell on March 26 and was admitted to hospital two days later.
The second was a man in his 70s who died in Burwood Hospital, Christchurch, after being among the group transferred from the Rosewood Rest Home.
Three of the four deaths in New Zealand are linked to clusters.
There are now 13 clusters of Covid-19 across the country.
The George Manning residential care facility in Christchurch is this country's 13th cluster where more than 10 people have been infected with Covid-19 from a single source.
Police have been out in force across New Zealand highways so far this Easter holiday, stopping and questioning motorists about their reason for driving - and reminding any holiday makers of the lockdown rules still in place.
Sergeant Andy Wallace said generally people were extremely compliant and he urged them to continue being so.
Wallace and his team ran multiple checkpoints on Thursday and stopped about 1000 cars.
