The Ministry of Health says seven new cases of COVID-19 have been found in managed isolation.
There were no new cases in the community to report on Saturday.
Of the new cases, one is from the US, one from Ukraine, four from Qatar and one from Dubai. All arrived between October 26 and 29.
"All cases were detected during routine isolation and testing processes and are now at the Auckland quarantine facility," the ministry said.
The total number of active cases in New Zealand is now 75, and total confirmed to date 1601. Just under 6000 tests were carried out on Friday.
The ministry said the family and household contacts of a child who travelled from New Zealand to Japan before testing positive have all tested negative.
"This public health investigation has also investigated the tests and possible historical exposures.
"It has been determined that it was not the result of a recent COVID-19 infection. There is no ongoing risk for New Zealand and the case is now closed."
Day 15 tests are being carried out on international mariners in isolation in Christchurch.
"All those who meet our low risk indicators, which include those who’ve recovered or have returned consistently negative test results throughout their stay, will be eligible to leave managed isolation from next Tuesday, November 3."
