Prime Minister Jacinda Ardern has announced that due to new community cases today evening, Auckland is moving back to Alert Level 3 for one week starting tonight.
A sibling of a Papatoetoe High School student, who was a casual plus contact of the recent Auckland community cases, has tested positive for Covid-19.
The Ministry of Health confirmed the case in a statement this evening.
Papatoetoe High School was due to reopen this Monday after having to close for cleaning and contact tracing when the first student of the recent cases tested positive on 14 February.
The new case reported today developed symptoms on Tuesday 23 February, and is regarded as being potentially infectious from Sunday 21 February.
The person was tested yesterday and the result was received this afternoon.
The high school student sibling had returned three recent negative tests and is asymptomatic, the ministry said.
Public health officials are undertaking interviews to help establish how this new case was infected.
The household has five people and testing is now underway, the ministry said, with results expected this evening.
Genome sequencing is also underway and expected later tonight.
A number of locations of interest, which will be available on the ministry's website, will be updated progressively from this evening.
Four have been identified so far:
