Testing has ramped up and police are cracking down on people leaving Auckland as NZ enters its second day at heightened alert levels.

Auckland is at alert level 3 and the rest of New Zealand is at alert level 2 after it was announced yesterday that there are four positive cases and four probable cases of Covid-19 outside of a managed isolation or quarantine facility.

This morning Mount Albert Grammar principal Patrick Drumm told Morning Report a student from the school tested positive for Covid-19.

Director-General of Health Ashley Bloomfield confirmed that the student was a close contact of the four existing South Auckland cases.

He says the school told staff, parents and students last night after they were made aware of the result.

Meanwhile, Police Commissioner Andrew Coster says people who are leaving Auckland for the wrong reasons are being turned back.

There are also massive queues and waiting times for people at Covid-19 testing stations.
