Health officials are tracking down the recent returnees who were staying at Auckland’s Pullman hotel at the same time as the community cases and are yet to be tested.
There were 353 guests who left the managed isolation facility between the 9-24 January, who had been asked to self-isolate and get tested following the discovery of the Northland case.
Two people have so far tested positive and 314 have tested negative.
Director General of Health Dr Ashley Bloomfield said most of the outstanding 39 people had been tested or had plans to get tested.
He said contact-tracing officials were tracking down the others who had not been in contact.
Returnees at all MIQ facilities will now have to remain in their rooms after their day-12 tests, Covid-19 Response Minister Chris Hipkins said yesterday.
There are 72 active cases of Covid-19 in New Zealand.
