To deal with the outbreak the entire state will enter a "circuit breaker" lockdown for seven days.
"The reason why we are dealing with this outbreak today is because of a hotel breach in South Australia - that is not a criticism, it is just a fact", he said.
The pause extension, which will last till 7:59 p.m. local time next Friday, is based on the public health risk assessment to further protect New Zealanders, Hipkins said, adding the country's public health staff remain in close contact with Victorian authorities about the actions being taken in Melbourne.
Unless there is a drastic improvement in the Melbourne situation, the affected teams will need to either be in NT quarantine, or be in another jurisdiction that has free access to the NT, by June 3.
Leading disease expert Professor Sharon Lewin of The Doherty Institute said the "highly infectious" Indian variant was "of concern".
The news comes after Victoria recorded another 11 Covid-19 cases overnight, bringing the state's total to 26 for the last three days.
"The next seven days in Victoria will be very challenging, and of course we are very mindful of the distress and the difficulty that this will impose upon people right across Victoria", he said.
While many would see waiting in line for two hours as doing their part for the nation, the man was clearly so frustrated he couldn't get the vaccine immediately, he was happy to express his opinion on Channel 10's national news.
Public gatherings are banned under the lockdown and restaurants, pubs and cafes can provide takeaway only.
He said Victoria might not be facing another lockdown had the federal government's vaccination rollout happened properly.
The man, in his 60s, could be the possible "source case" of the Whittlesea outbreak, although a definitive link is yet to be established.
That sparked a surge testing effort in Melbourne that has raised the number of confirmed cases to 26, with infections linked to shopping centres, football matches, a swimming school and a series of nightclubs.
The state reported 11 new cases on Thursday, and one person is on a ventilator in the intensive care unit.
New Zealand has already suspended its travel bubble with Victoria and while residents are now being shut out of other Australian states, prompting major airlines to slash Melbourne services.
"If we had an alternative to hotel quarantine for this particular variant of concern, we would not be here today". The virus has leaked out of make-shift hotel quarantine facilities across Australia 17 times in six months, according to the opposition Labor party.
He also announced from tomorrow, dependent on supply from the federal government, all Victorians over 40 will be eligible for the Covid-19 vaccine.
From Friday morning, Victoria will expand the eligibility for vaccinations, with people in the 40 to 49-year-old age group able to receive the Pfizer jab at state-run vaccination sites.
"I really encourage everyone, if you're eligible, get vaccinated", Mr Merlino said.
