UPDATE 1.23PM: The investigation into how a cleaner at the Grand Millennium, referred to as Case A, was exposed to Covid-19 is continuing.

Case A and a household member whose result is under investigation remain at the Auckland quarantine facility, says a statement from the Ministry of Health.

"The household member has returned a second negative test at Day 5, which reinforces the belief that their initial weak positive test was either a false positive or an early and fleeting mild infection that has now passed," says an MOH spokesperson.

"This person continues to be managed as a close contact and is not considered to be a confirmed case at this stage."

All close and casual contacts of Case A have returned negative initial tests. They are due to have their Day 5 tests today and tomorrow. Results of those will come in over the weekend.

"Contact tracing teams are contacting the 250 returnees who have left the facility since March 10; asking them to get tested immediately and remain at home until they have had a negative test result returned.

"As at 9am this morning, 193 of those 250 people have been contacted and the remaining people are being followed up today. If you are one of these people, please get in touch with Healthline.

"We also yesterday put in place immediate additional steps including additional onsite testing and exit tests for all returnees leaving the facility. The public health risk from the Grand Mercure is considered low."

"Poster scans have reached 231,767,115 and users have now created more than 8,770,858 manual diary entries," says the MOH.

"It's incredibly important we all scan the QR codes wherever we see them, as the more we all scan, the safer we'll all be. If you can't scan then please keep a record of where you have been. The NZ Covid Tracer app is one way to do this through the manual entry option.

"A reporting error meant Covid Tracer app data in yesterday's media release was incorrect, and QR code scan numbers were under-reported by approximately 300,000 scans. The data reporting is being manually corrected. The data reported today is accurate."
