There is one new case of Covid-19 in managed isolation and quarantine (MIQ) facilities today.
In a statement, the Ministry of Health said there were no community cases.
It said today's case arrived in the country on 25 May via Qatar and is now in an Auckland managed isolation facility.
The ministry also said two previously reported cases have now recovered.
The seven-day rolling average of new cases detected at the border is two.
The total number of active cases in New Zealand today is 21. The total number of confirmed cases is 2,314.
Since 1 January 2021, there have been 64 historical cases, out of a total of 498 cases.
Today's Covid update comes after the Victorian government just announced a lockdown, in a bid to curb a growing outbreak in the state.
New Zealand's quarantine-free travel bubble with the state has paused in the meantime and will be reviewed.
"New Zealand officials are in close and regular contact with Victorian authorities about their just announced seven-day lockdown. An update on quarantine-free travel between Victoria and New Zealand is expected to be released later today," the ministry said.
It said the number of positive Covid-19 case numbers in Melbourne continues to rise and was at 34 at 1pm (NZ time) according to Health Victoria.
"The number of locations of interest being announced by Health Victoria is also continuing to rise and there are now 150 exposure sites across Melbourne."
"Given the time frames, it is crucial that everyone who has been in the state of Victoria since 11 May keeps checking Victoria Health's website detailing the locations of interest."
The ministry reminded people that anyone who has been at a location of interest at the specified time must immediately self-isolate and call Healthline on 0800 358 5453 for advice on when to get tested.
"Anyone in New Zealand who has been in the wider Melbourne area since 11 May who develops symptoms while in New Zealand should also ring Healthline and arrange to get tested."
And anyone who has been in the Whittlesea local government area since 11 May should also ring Healthline for advice, the ministry said.
"Given this increased risk, it's critically important everyone keeps a record of where they've been by scanning QR codes or keeping a manual diary of their movements. It can help contact tracers quickly find potential close and casual contacts if there is a positive Covid-19 case here in New Zealand," Director-General of Health Dr Ashley Bloomfield said.
"And of course, anyone with Covid-19 symptoms should isolate, be tested and remain isolated until the receive their test results."
Meanwhile, the ministry has changed its timeline on when the general public will be vaccinated from "from July" to "from the end of July".
Pfizer had been confirming delivery schedules and quantities about four weeks ahead of when the shipment was expected, Covid-19 Response Minister Chris Hipkins said.
The company had a contractual commitment to deliver the rest of the vaccines between July and September.
Remaining supplies were still expected by the end of September, spread over the three-month period, he said.
Yesterday there were 4,990 Covid-19 tests processed. The seven-day rolling average is 3,751.
The total number of tests processed to date is 2,121,676.
