In a statement this afternoon, the Ministry said the new historical case reported today is a person who arrived from India on February 28 and returned negative test results while in managed isolation, before returning a positive test result as part of an employment requirement.
"Subsequent investigation, including serology testing, has determined this to be a historical case."
There have been 42 historical cases since January 1, out of a total of 313 cases. The Ministry said it was important to reiterate that historical cases are not considered to be infectious.
The other new imported case reported today arrived from India on March 23.
On Friday, there were three new imported cases reported by the Health Ministry.
The total number of active cases in New Zealand is 74 and the total number of confirmed cases is 2125.
The Ministry said the investigation into how a cleaner at the Grand Millennium was exposed to Covid-19 is continuing.
"All close and casual contacts of Case A have returned negative initial tests. We expect further test results in the coming days."
It was also announced yesterday that the Ministry was investigating the possibility of a transmission at the Grand Mercure managed isolation facility after an infected returnee took part in a walk that required travel by bus.
MIQ boss Brigadier Jim Bliss said earlier this month 23 people were bussed to two managed isolation walks, which a now-known positive case took part in.
Bliss said he had put a 24-hour pause on bussing returnees to managed isolation walks to allow staff to review their processes and make sure their protocols are appropriate.
Director-General of Health Dr Ashley Bloomfield said more than 5000 vaccine doses would be administered over the weekend and that by the end yesterday more than 50,000 doses were administered.
