Health officials are investigating a suspected community case of Covid-19 in Northland.
Covid-19 Response Minister Chris Hipkins would provide an update on the case at a press conference at 4pm on Sunday.
The case is related to someone who was recently released from managed isolation and quarantine, NZ Herald reported.
In the last Ministry of Health update on Friday, there were nine new cases to report, all in managed isolation.
Three of the cases were travellers returning from the United States, and two were from the United Kingdom, two from India and one each from the United Arab Emirates and Kazakhstan.
Earlier that day, Covid-19 Response Minister Chris Hipkins announced optional saliva testing would be available for border workers in quarantine facilities from Monday.
* Covid-19: One year on since first Covid-19 test in NZ, nine new cases at border
* Covid-19: Voluntary saliva testing to be offered to quarantine workers
* Covid-19: Six new cases of coronavirus detected at the border
It is the first time Covid-19 saliva testing has been offered by the Government.
This new precautionary measure is in response to higher rates of infection overseas and the more transmissible variants of Covid-19.
The saliva tests would be offered on a voluntary basis, and would not replace nasal swabs, Hipkins said.
It was hoped the saliva tests would mean any positive cases among workers at quarantine facilities would be picked up faster and workers would be provided with another layer of assurance.
