The Ministry of Health has reported 11 new cases of COVID-19 in New Zealand, all picked up in managed isolation.
There are no new cases in the community.
Five were picked up in day six testing of the international fishing crew in Christchurch.
"We have always expected that additional cases from this group were likely," the ministry said in a statement.
The other cases include a family pair who arrived from Amsterdam via Singapore; two arrivals from the UK; and one from UAE.
All six tested positive in their day three tests, and have been moved to quarantine.
There are now 74 active cases in New Zealand, a total of 1578 since the pandemic began.
On Friday 7700 tests were processed.
"The metro Auckland DHBs are monitoring the demand for weekend COVID-19 testing and are ready to further increase testing capacity if needed," the ministry said.
One facility, in west Auckland's Henderson, opened early as there were people queueing. Other testing outlets open in Auckland on Saturday are the Northcote Community Testing Centre, Northcare Accident and Medical, Whânau House in Henderson, Western Springs Community Testing Centre, the Whânau Ora Community Clinic in Wiri, the Otara Community Testing Centre, and the North Harbour stadium carpark in Albany.
"COVID-19 testing is also available across metro Auckland at a number of urgent care clinics and general practices over the long weekend. A reminder that wherever you get swabbed, a COVID-19 test is free of charge."
