LAST UPDATED AT 6:45PM
Auckland will move down to COVID-19 Alert Level 2, and the rest of New Zealand Level 1, at midnight Wednesday.
Prime Minister Jacinda Ardern said these restrictions will remain in place until Monday.
Papatoetoe High School will be closed until Monday.
Ardern said everyone throughout the country needs to wear masks on public transport for now.
Third new community case on Wednesday
The update comes as a third new case of COVID-19 was found in the community on Wednesday.
This person is a household contact of the brother and sister from Papatoetoe High School, confirmed as new cases earlier on Wednesday.
The newest case was isolating at home, as were the brother and sister.
The sister is a classmate of an original case, who tested positive over the weekend.
The newest case works at McDonalds. They didn't have symptoms when they tested positive.
Director-General of Health Ashley Bloomfield said it's reassuring the new cases are all linked and were picked up through the testing system.
There are now six known cases of COVID-19 in the community - the South Auckland mother, father and daughter (who attends Papatoetoe High School), and now the Papatoetoe High School siblings and their household contact.
The South Auckland mother works for LSG Sky Chefs, which provides laundry and catering services to domestic and international airlines. She was therefore exposed to the border. The father is a tradesman.
The source of the infection remains unknown.
See an updated list of places of interest, visited by COVID-19 cases, at the Ministry of Health's website.
Bloomfield was reassured that by late Wednesday afternoon, 30 of the original Papatoetoe High School case's 31 close school contacts had returned negative results. The positive case is the one we learned of earlier on Wednesday.
Of the 1523 "casual plus" contacts identified at the school, 363 were still awaiting test results.
Earlier on Wednesday, the Ministry of Health reported that only 76 of the original South Auckland family's 128 close contacts had returned negative results.
Asked by interest.co.nz at around 5pm how many of the 128 remained outstanding, Bloomfield said the results yet to come through were for people who were in the same doctor's waiting room as the South Auckland father. Bloomfield said the risk to these people was low as subsequent tests done on the father came back as negative.
The father is still being treated as a positive case.
On Tuesday 17,439 tests were processed.
Results have come back for wastewater tests taken on Monday. ESR (Institute of Environmental Science and Research) has found no evidence of COVID-19 in the wastewater sampled.
Resurgence Support Payment available
Because Auckland will be at Level 2 or above for seven days or more, businesses all around the country will be able to apply to receive the new Resurgence Support Payment.
Businesses need to have experienced a 30% drop in revenue over a seven-day period, due to a change in alert levels to be eligible.
Qualifying businesses can get $1500 plus $400 per employee up to a total of 50 fulltime equivalents ($21,500).
The payment is being administered by the Inland Revenue.
The Wage Subsidy isn't available, as no part of the country is at Level 3 or above for seven days or more.
