Prime Minister Jacinda Ardern has announced Auckland will move to alert level 3 from 6am tomorrow (Sunday 28 February) for seven days, while the rest of New Zealand moves to alert level 2.

The announcement comes after 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 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.
