There are 24 new Covid-19 cases in the community in New Zealand on Sunday, all of which are in Auckland, Director of Public Health Caroline McElnay has confirmed.
The total number of cases in this outbreak is now 1050, of which 361 remain active.
Twenty-one of the new cases have been epidemiologically linked to the outbreak. The remaining three are under investigation.
There are now 13 people with Covid-19 in hospital, including four in intensive care. There are seven cases at Middlemore Hospital, five at Auckland City Hospital and one at North Shore Hospital.
There are 1215 contacts currently being managed, of which 85 per cent have been contacted and 87 per cent have received at least one test.
Currently there are 134 locations of interest on the Ministry of Health’s website.
"We do expect a number of further cases in the coming days as some of the new recent cases do come from large households," McElnay said.
"What we know about Delta is that's it's more infectious so we do expect more household contacts to subsequently test positive, but these contacts are already in isolation."
On Saturday, 13,833 tests for the coronavirus were processed in New Zealand, adding to a total of 3.23 million in New Zealand since the pandemic began.
Also on Saturday, there were 53,386 Covid-19 doses administered in New Zealand, made up of 28,946 first doses and 24,440 second doses.
More than 4.68 million doses have been administered in New Zealand in total.
There are no new border cases.
However two previously reported cases have been re-classified as not being cases, resulting in a net increase of 22 cases on Sunday.
This means the total number of confirmed Covid-19 cases in New Zealand since the pandemic began is 3704.
There was a positive wastewater detection in a sample from Pukekohe collected on Wednesday, which follows a positive detection a week earlier then non-detection on Friday.
"The result is believed to be linked to known cases in the area," the Ministry of Health said.
Auckland remains in Alert Level 4, while the rest of the country is at Level 2. Cabinet will meet on Monday to review the country's alert levels.
McElnay was joined by Prime Minister Jacinda Ardern for Sunday's update.
