COVID-19: Prime Minister Jacinda Ardern mum on trans-Tasman bubble date

Prime Minister Jacinda Ardern is staying mum on when Kiwis can expect to travel between New Zealand and Australia quarantine-free.

A review of the proposal to open a trans-Tasman bubble will take place in Cabinet on Monday, but Ardern told The AM Show that doesn't mean the floodgates will open.

"No-one should expect that suddenly, at the end of today, we're going to have an opening. I don't want to raise that expectation but we have said it will be soon." 

The Opposition has been pushing for a travel bubble between New Zealand and Australia for months but the National Party ramped up the pressure on the Government last week, launching a petition calling for its immediate implementation. 

Ardern said on Monday the bubble is something the Government had been "working hard" on.

"We just need to make sure when we do it, we get it right," she said. "A petition isn't what makes this decision - we make it based on health advice and when we believe we've got everything in place." 

The Prime Minister declined to say if an in-principle decision would be made on Monday.

"I'm not going to get ahead of the Cabinet talks today but today is not the day that you're going to get that final date and decision," Ardern told host Duncan Garner.

"It will be soon - but the things that we need to do to get this right… that's what we have to work on."

National leader Judith Collins last week said the travel bubble needs to happen now.

"I would be opening it today unless there's some evidence that there are any problems," she told The AM Show.

Ardern said an update will be provided during her weekly post-Cabinet press conference at 4pm on Monday.
