New Zealand is entering its second day at heightened alert levels after four people in the community tested positive for COVID-19.

New Zealand has 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.

Mount Albert Grammar is one of the biggest schools in the country.
