Calls for New Zealand to open its borders was "frankly dangerous", Prime Minister Jacinda Ardern says.
She said New Zealand was in a privileged position due to its "hard-won gains", and opening the borders up while the pandemic was escalating came at a potential price.
Imported cases had led to outbreaks in New Zealand, and the reason for the current freedoms in New Zealand was because of the strict border measures, she said.
Ardern said opening up more to Australia and the Pacific was being considered, but anyone pushing for more open borders now was irresponsible.
Four more quarantine facilities to open
Four more quarantine facilities are due to open as more Kiwis arrive home from overseas, Ardern says.
Ardern said the number of people in quarantine or managed isolation was 4858, and there was breathing space as there was capacity for 6103.
She said back up capacity was also available.
She did not have the names of the four new hotels on hand.
Ramping up capacity was needed to match the increasing inflow of returning Kiwis, she said.
Of the 1200-odd spare beds in quarantine and managed isolation facilities, she said the numbers were increasing and that spare capacity would soon be filled.
Asked about sharing briefings with the National Party, Ardern said she shared information publicly as soon as it was possible.
On APEC 2021 going virtual, Ardern said there was too much uncertainty about face to face meetings.
She said a "wide range of options" were considered about APEC 2021, but making it virtual was a "balanced decision" in an uncertain Covid environment.
The transtasman bubble and opening the border
The Prime Minister said opening the border with countries in the medium term depended on a number of factors including the turnaround time for tests, how rampant Covid-19 is, the ability to treat a large number of people and whether there is a vaccine available.
National leader Todd Muller did not call for borders to be opened up in the short-term, but asked for clarity around the criteria for mandatory quarantine measures in the medium and long term.
Asked if she was referring to the Opposition when she said it was "dangerous" to call for immediate easing of border restrictions, Ardern said it was up to the Opposition to articulate its position.
"Covid is not over. It's not going to be over for some time."
