There are 13 new Covid cases in the community, director general of health Ashley Bloomfield says.
Twelve are linked to the current cluster and one remains under investigation but is believed to be linked.
Ninety-eight people linked to the cluster have been moved into quarantine facility.
There are six people receiving hospital-level care. Two are in Auckland City Hospital on a ward, and four people are in Middlemore.
The total number of active cases in New Zealand is 90, of which 69 are from the recent cluster, one more in the community, and 20 are imported cases in managed isolation and quarantine facilities.
The travel history of the current cluster included the Pak n Save in Apirana Ave in Auckland, on July 31 at 10.09am and again on August 8.
Bloomfield said people were in those locations should be aware of symptoms.
Isolation hotel worker tests positive
Bloomfield said genome sequencing has shown a positive case unconnected to the current cluster. The new case is a man who worked at the Rydges Hotel managed isolation facility.
That could indicate a new chain of transmission, and officials are now rushing to ring-fence the case through tracing and isolating close contacts.
Bloomfield said there were 1880 close contacts of the cluster, 1691 of whom have been contacted and are self-isolating.
He repeated that casual contacts were at very low risk of infection.
The surface testing from Americold was still to be completed, but Bloomfield said people being infected from those surfaces was essentially now ruled out.
The Rydges worker did not have any routine contact with guests, and no other cases have been linked to him so far.
He returned a positive test on August 16 after first having symptoms on August 11. He was transferred to Jet Park Hotel quarantine facility on August 17.
His genomic sequencing results, which came back this morning, match those of a Kiwi who flew in from the USA and was also at the Rydges Hotel from July 28 to July 31, before being moved to the Jet Park Hotel after a positive test.
"At this stage there is no obvious person-to-person connection between the worker and the returnee from the USA but investigations continue," the ministry said.
Initial reviews of CCTV footage and swipe card movements so far show no interaction between them, including no entry to physical locations visited by both of them.
The room the USA returnee was in has been hospital-grade cleaned. It has not been unoccupied since the returnee was there and it remains empty.
"Contact tracing and testing has not connected any further cases to the maintenance worker, and to date this remains a single case," the ministry said.
Six close contacts he worked with at the Rydges Hotel have been identified and are in self-isolation. They have all returned negative results from surveillance testing last week, but all staff and returnees at the Rydges are being retested again as a precaution
Three household close contacts of the man are all in self-isolation and have been tested.
The man attended two of the Emmanuel Cook Islands Good News Fellowship church services on the morning and evening of August 9.
Health officials have contact-traced all attendees as close contacts, and they are in self-isolation.
The venue of the service is a school hall and deep cleaning of the facility is currently underway.
Health officials are currently assessing if environmental testing at the Rydges would provide any further insight.
Yesterday the cluster grew by nine cases, while over 26,000 test results had been returned in the previous 24 hours.
The cluster size grew to 58 cases - with five people in hospital - while almost 100,000 tests have been conducted since the first cases came to light last week.
Hipkins told the Herald yesterday that the outbreak appeared to have been detected before it had a chance to explode - not only in Auckland, but all over the country.
But that was before the news emerged of a positive case unconnected to the cluster.
The current alert settings - level 3 in Auckland and level 2 in the rest of the country - are in place until 11.59pm on August 26, but Cabinet will review the settings on Friday.
