Since the last update on Monday, there are 7 new cases of Covid-19 in managed isolation.
Three of the cases are part of the group of international mariners who arrived from Russia via Singapore.
One person travelled from India via United Arab Emirates, two from United States flew direct from Los Angeles and one person travelled from Puerto Rico via Los Angeles.
One previously reported case has been removed from New Zealand's tally as it's being investigated as a possible historical case.
The total number of active cases in New Zealand is 62, after 21 cases have recovered. The total number of confirmed cases is 1,872.
There are now 2,439,100 registered users of the Covid tracer app, with 151,801,799 poster scans and 6,127,918 manual diary entries.
Four new cases were announced at the last briefing on Monday. Three of the cases were in managed isolation in Christchurch and were all among a group of international mariners who arrived in the country, the ministry said.
The fourth case arrived from the UK and had been transferred to the Auckland quarantine facility.
On Monday the total number of active cases in New Zealand was 77 and the total number of confirmed cases was 1866.
There have been 1,441,163 Covid-19 tests processed by laboratories to date.
New Zealand's managed isolation facilities now house both the highly-transmissible UK variant of Covid-19 and a new one associated with South Africa.
Almost a quarter of the country's live cases are now the UK variant with that number expected to increase.
Meanwhile, managers at managed isolation facilities have told RNZ that their workers are encountering unfair stigma in the community, and the pressure has been so bad that some have quit because of it.
Charge nurse Kerry Washington said her nurses in Christchurch had been confronted in supermarkets, barred from going to their children's school meetings or onto school grounds to pick children up, and some have had difficulty getting routine doctor or dentist appointments.
In Auckland, staff working at the Waipuna Hotel have had friends and family reluctant to meet, and business contacts had repeatedly cancelled appointments where hotel staff had already travelled to another city to meet, after they realised what the hotel was being used for.
