Amid the results of the Covid-19 managed isolation review, Prime Minister Jacinda Ardern wants people to remember that testing has shown no evidence of the coronavirus in the community.
The review found the managed isolation and quarantine system to be under "extreme stress" and unable to respond to the increasing demands being placed on it as more New Zealanders returned home.
Ardern told Morning Report today there had been 80,000 tests for Covid-19 in the past 13 days with no positive results in the community.
"Here we are at the bottom of the world as this pandemic is surging -10 million cases ... the reason we are seeing these extra cases at our border is because the pandemic is growing not slowing, and New Zealand has been on a different trajectory to the rest of the world.
"What you are asking is, is it possible to keep it that way? That is what we are putting all of our effort into ... it is a very difficult task though."
She said New Zealanders should have confidence in the government's response because it had "adjusted our settings every step of the way based on what we've learnt, based on what we know is working and based on what needs to be done. So while there is no playbook, we have been very agile."
It was put to Ardern that a clear finding of the report was that ministers had been making policy decisions that weren't able to be carried out on the ground.
"I know the bit of the report you are referring to but actually, the issue that you have raised around we set a clear direction, so did the director-general of health. We all did. and then whether or not it was happening on the ground was more an issue of ... the fact that we have MBIE, we have health, we have police, we have Avsec, we have the defence force all working on quarantine ... there have been so many different elements.
"The reason we have had as you describe it as struggling is we have a 73 per cent increase of New Zealanders coming through the border since April into quarantine... New Zealanders are afraid, so they are coming home.
"We do have the ability to manage that, what we need though is a system that gives us a bit more warning than a passenger manifest when the doors of a plane close."
Asked about who should be taking responsibilities with issues in the system, Ardern said: "We have all been taking responsibility for this. There is not one person to blame for all of this ... we just have to fix it."
The government was working as rapidly as possible to fix managed isolation, but Ardern said the basic elements of the system needed to be dealt with before provisions around compassionate considerations.
Demand for managed isolation expected to increase
The head of managed isolation, Air Commodore Darryn Webb, told Morning Report: "We are seeing a lot of New Zealanders who are looking back at New Zealand and saying 'we really want to be at home' and of course it is their right to return home so the inflow in terms of numbers coming home is growing significantly.
"Early on we were seeing 20 flights a week with low loadings, maybe 10 per cent of the normal capacity. That's grown now to 30 flights per week with 30 per cent loading, so it is growing rapidly."
The maximum capacity for managed isolation at the moment was 5764 people.
"We do have an ability to meet a growing need, but there's no doubt from a system perspective, growing supply and demand both work closely together so we will have to think about those supply issues as well."
Webb said policy settings had to be looked at in order to regulate the number of incoming people.
"Kiwis aren't great at advance planning. So while somebody might book a ticket with an intention to travel, it doesn't always translate into boarding the plane. So we get a picture, but often it's not actually until they have checked in and they've actually put themselves on an aeroplane that we have absolute certainty that we're going to see them arrive in New Zealand.
"For a 12-hour flight that's reasonable notice, but for a shorter flight, that doesn't always provide a huge amount of ... lead time. So it's quite a challenge to keep that system working effectively."
He expected the number of people returning to New Zealand to increase.
"That's why we need to advance those policy decisions with some urgency. That is being addressed by Government and they will be taking things through Cabinet in the next few weeks."
He didn't see personal protective equipment use as a concern, but had been talking to Dr Bloomfield about a "simple and consistent" approach to PPE.
Additional safety measures to implement could include mandatory masks for all new arrivals from aircraft to room and a requirement to stay inside for the first three days of managed isolation.
New agency needed - epidemiologist
University of Otago epidemiologist, Professor Michael Baker, told First Up the outcome suggested a wider review of the response to the novel coronavirus was needed.
He was still confident that the managed isolation would be robust if guidelines suggested by the review were implemented.
But he wanted a new agency to lead the response.
"I think given the threat from the pandemic and the need for a highly integrated approach, we need a new agency for New Zealand, quite clearly, to manage the pandemic and some of the other threats on the horizon... we look at all the requirements of this pandemic, it has put a huge strain on the public sector. It would be much more efficient to have a new agency dedicated to this task going ahead."
