Australia and New Zealand are committed to introducing a trans-Tasman travel zone "as soon as it is safe to do so".

Australian Prime Minister Scott Morrison is currently holding a press conference, after Jacinda Ardern joined the start of the Australian national Cabinet meeting earlier today.

The trans-Tasman bubble would ease travel restrictions between the two counties and would be put in place once the necessary health, transport and other protocols had been developed, the two prime ministers said in a joint statement.

The pair said the arrangement recognised both Australia and New Zealand were successfully addressing the spread of Covid-19.

"Building on our success so far in responding to Covid-19, continuing to protect Australians and New Zealanders remains an absolute priority.

"We will remain responsive to the health situation as it develops."

Ardern was invited by Morrison to the meeting, which included the Premiers and chief ministers of all states and territories. The last New Zealand Prime Minister to join was Peter Fraser during World War II.

Ardern was tight-lipped about the meeting this afternoon, saying because it was still ongoing she couldn't reveal the details of what was discussed.

Australia has now recorded more than 6800 cases of Covid-19, with 3035 in New South Wales, 1423 in Victoria, 1043 in Queensland, 438 in South Australia, 551 in Western Australia, 223 in Tasmania, 107 in the Australian Capital Territory and 29 in the Northern Territory.

The death toll stands at 96.

Minister of Foreign Affairs Winston Peters said the Australasian population had to see itself "as one" with a system united in the attack on Covid-19.

Peters wanted it to be treated as a matter of "critical urgency".

Fifty-five per cent of New Zealand's tourists were Australians while New Zealanders were the second-largest group of tourists in Australia.

"We've got a lot at stake here so we've got to think outside the square and think as one ANZAC nation."

If both countries had the same technology, utilities and "had that confidence" the bubble could go ahead.

Asked whether he's like to see the transtasman bubble by the start of the ski season, Peters said:

"Urgency is everything at the moment. I know we've got to defeat Covid-19 but at the same time we've got to get this economy turned around and with the greatest of speed. Every day of delay is a day of setback."

Peters wanted a public-private sector taskforce to work on the transtasman bubble.
