Another 41 community cases of COVID-19 were reported on Saturday, 21 of them without links to previous known cases.
Forty were in Auckland, and one in Waikato, the latter a household contact of two existing cases.
Thirteen are household contacts of existing cases.
The latest figures come as the country takes part in Super Saturday, a mammoth effort to get as many Kiwis vaccinated as possible in a single day. The target is 100,000 and as of 1pm, 70,000 had been done - 19,773 of them first doses, and 4490 first doses in Auckland.
"Vaccination remains our number one protection against COVID-19," the ministry said in a statement. "The Vaxathon is encouraging New Zealanders - particularly young Māori, Pacific and people living with a disability - to get vaccinated."
The current outbreak has now had 1895 cases, mostly in Auckland.
Thirty-five of Friday's 64 cases had exposure events, the ministry said. In the past 14 days, there have been 124 cases where no link has been uncovered.
There are 31 people in hospital at present, six in ICU or HDU.
There were two new cases reported at the border.
A woman associated with the two women who travelled to Northland has tested positive for COVID-19 and is in an Auckland quarantine facility, the ministry said.
"Public health officials have determined she wasn’t infectious while she was in Northland between 2-8 October. Her infectious period has been determined as beginning after she returned to Auckland.
"Three household contacts and two other contacts have been identified by public health officials. These contacts follow a visit to a private home in Auckland and shared transport to the testing centre."
Wastewater testing in Beachlands, Wellsford and Pukekohe has come back positive, and people showing symptoms are urged to get tested.
Earlier, the Australia state of Victoria reported 1993 Covid-19 cases and seven deaths. Despite this, the state is expected to reopen in the next week or so as vaccination targets are met. More than 87 percent of people 16 and over have received at least one dose, and 63.8 two.
NSW reported 319 cases and two deaths in the 24 hours to 8pm Friday.
