New Zealand remains ahead of its modest COVID-19 vaccination targets.
On Wednesday, new health ministry data showed the number of Kiwis to have received one shot had grown to 432,509 - or just under nine per cent of the population.
That places New Zealand 119th in the world.
Around four per cent - 235,606 - are fully vaccinated with their two doses of Pfizer.
Despite the low proportions, NZ's rollout is nine per cent ahead of schedule.
The vaccination rollout in Aotearoa aims to ramp up dramatically from next month, when the general public will begin to be eligible.
That means, like Australia, New Zealand is at risk of future outbreaks until mass vaccination begins.
The government has also warned New Zealand could run out of vaccine.
It has around 300,000 doses on hand after delivering 106,000 doses in the past week.
However, Pfizer is yet to confirm its delivery schedule for the next month - though ministers are confident they soon will.
There has not been a case of COVID-19 in the community in New Zealand since February.
Kiwi health officials will assess the quarantine-free travel suspension with Victoria on Thursday.
There's little prospect of repatriation flights or assistance to New Zealanders stuck in Melbourne.
"Our message from the very beginning of the trans-Tasman bubble has been flyer beware," Associate Health Minister Ayesha Verrall said.
"They need to understand they may need to shelter in place for some time."
