There are three new cases of COVID-19 to report today (Sunday July 5) in managed isolation and quarantine facilities in New Zealand. 

There continue to be no new cases in the community, the Ministry of Health said in a statement.

The number of active cases in New Zealand is 21, all of which are in managed isolation or quarantine facilities.

The total number of confirmed cases is 1,183, the number reported to the World Health Organisation.

One person remains in Auckland City Hospital in a stable condition on a ward.

One significant cluster remains open and is due to close on Monday July 6.

All three cases being reported today arrived into Christchurch on June 30 on a flight from Delhi. Their flight had transited at Singapore but they did not leave the plane there.

All have been in managed isolation since their arrival in Christchurch and their cases were detected during day three testing. All are now in quarantine at the Chateau on the Park facility.

The first case is a woman in her 30s. The second case is her husband, a man in his 30s. Their close contacts include two daughters who will be tested today and who have also been moved into the quarantine area.

The third case is a man in his 70s, travelling with his wife who is regarded as a close contact.

Globally, the latest reporting from the WHO is of 212,326 new cases of COVID-19 - the largest daily increase on record.

This figure and the cases reported here today continue to reinforce the critical importance of our border controls in keeping New Zealand and New Zealanders safe, the Ministry said.

Every person who arrives in New Zealand must be isolated from other people in New Zealand for a minimum period of 14 days. They must also test negative for COVID-19 or if a case be cleared by health authorities before they can go into the community.

The 14 day period will continue to be vitally important as a key protection measure during the global pandemic, the Ministry said.
