The Prime Minister is urging people feeling unwell to refrain from attending the mosque attack memorial service in Christchurch.
Jacinda Ardern has given Christchurch's Sunday gathering a green light following advice from experts that there is still no community outbreak.
Ardern said while unlikely, that advice could change before Sunday. Cancelling the event couldn't be "ruled out entirely" should that advice change, she said.
"I will always base my decisions on the most up to date information," she told reporters in Christchurch on Friday.
"If you feel unwell do not attend the memorials on March 15 and for those who are attending - making sure people of course acknowledge close contact protocols."
The announcement the March 15 service would go ahead comes after the cancellation of Auckland's Pasifika festival earlier on Friday.
"We have always been willing to move to support New Zealand's public health," Ardern said.
"Every single case we've had, regardless, we have treated the same in terms of contact tracing - that will be the approach we continue to take."
