WELLINGTON, Sept. 26 (Xinhua) -- New Zealand reported two cases of COVID-19 on Saturday, said the Ministry of Health in a statement.
Of Saturday's cases, one was an imported case detected in a managed isolation facility and the other was a historical case detected during contact tracing. Meanwhile, there was no new case of COVID-19 in the community, said the ministry.
The historical case was tested because the person was among the passengers including confirmed cases on a recent charter flight from Christchurch to Auckland. However, the infection would have occurred overseas prior to the person returning to New Zealand earlier this month and the person was no longer infectious, said the ministry.
According to the statement, the ministry said that historical cases were some people who could return a positive PCR (Polymerase chain reaction) test long after they had recovered from the illness and were no longer infectious.
Currently there are 61 active cases in New Zealand. The total number of confirmed cases of COVID-19 in the country is 1,475.
Laboratories across New Zealand processed 5,952 tests during the past day, bringing the total number of tests completed to date to 943,196.
