As of Sunday morning there were 1,039 cases in the country, up 89 from the previous day, while still only one person has died as a result of complications from Covid-19, the disease caused by the virus.
New Zealand's director general of health, Ashley Bloomfield, said at a news conference 156 patients have recovered.
The largest cluster of cases, 66, are connected to a school in Auckland, Bloomfield said.
Prime Minister Jacinda Ardern said New Zealanders had mostly been complying well to strict lockdown policies, which had contributed to the disease spread being below what modelling had predicted.
"Our case rate and death toll is well below other comparable countries," Ardern said at the same news conference.
"Yes, we had the benefit of time because our distance and because our early border and mass gathering measures also made a difference there."
Bloomfield also praised New Zealand's newly established National Close Contact Service, which had traced 4909 close contacts of coronavirus patients as of Saturday. It was set up on March 24, with 702 contacts traced in a single day on Thursday. - dpa/Asian News Network
