Westpac has confirmed that a staff member at its head office has tested positive for Covid-19, and employees are being asked to monitor their health.
The bank spokesman said the non-customer facing employee contracted it from a close contact.
"As soon as they became aware a member of their household had contact with a Covid-19 case, the employee self-isolated. The self-isolation started last Friday evening and official advice is that the staff member would not have become infectious until Tuesday of this week."
However, the spokesman said, as a precaution, the bank was deep cleaning the workspace and floor where the staff member worked.
He said other standard Covid-19 procedures, including asking the employee's colleagues to monitor their health, had been instituted.
"We're in frequent contact with this employee and are offering full support," the spokesman added.
Nine new cases - eight in managed isolation and one household contact of one of the marine employee cluster cases - were reported in New Zealand today, director general of health Dr Ashley Bloomfield said.
The Ministry of Health confirmed this case was included in today's numbers.
Snap Fitness general manager Brendan Hurrell said Auckland Regional Public Health had this afternoon informed him all 10 close contacts from the Browns Bay gym's boot camp had been traced, tested and were isolating.
He said his manager's test results had returned negative, which he said was a "positive start".
Hurrell said they had decided to push back the re-opening of the branch until Sunday morning to make sure there were no new developments in the next 24 hours that would affect the business or its members.
"We just thought we'd be safe." he said.
Malt owner Kevin McVicar said all of his staff had also tested negative but would need to completed their isolation period given they were considered close contacts of the patron who visited last Friday.
There are 1923 confirmed cases, and 66 active cases.
The one new community case is a close household contact of one of the cases from the marine employee cluster.
New Zealand's labs completed 6053 tests yesterday.
