There are two new cases of Covid-19 in managed isolation, the Ministry of Health has said in a statement.
There are no new community cases today.
Both of the new cases arrived on November 19 and tested positive around day 3 of their isolation.
One arrived from the United Kingdom via the United Arab Emirates and the country of origin for the second case is still being determined.
There are now 52 active cases of Covid-19 in New Zealand.
The Ministry of Health also said that it wrongly reported that a new case linked to the Defence Force cluster was a border worker.
The person was actually a close contact of "Case B", a Defence Force staffer.
There were 3274 tests around the country yesterday, bringing the total number of tests since the pandemic began to 1.23 million.
There are six confirmed cases in the Defence Force cluster.
Meanwhile, the ministry is investigating a possible case of Covid-19 contracted by an Air New Zealand staff member in China, according to TVNZ.
"In conjunction with the company, the ministry will continue to investigate the circumstances of this possible case," the ministry said in a statement.
The ministry reiterated that at Alert Level 1 anyone who became unwell with cold or flu symptoms anywhere in the country should seek a test quickly, and stay at home.
"If you are unwell, sacrifice your plans and protect your family, friends and colleagues by staying at home and getting a Covid-19 test.
"It is the best way to ensure the freedoms we enjoy under Alert Level 1 can continue into the much-anticipated summer break."
The ministry also said the New Zealand contact tracing app would be updated tonight to make it easier to use.
Existing app users would no longer need to be prompted to log back into the app with their password, and new users would not have to provide their email address.
