Covid Response Minister Chris Hipkins has admitted being dubious about infection-rate modelling in light of international projections that tens of thousands of new community cases would be surging across New Zealand by this long Waitangi Day holiday weekend.
"I've always been pretty sceptical about the models," he told Newstalk ZB's Mike Hosking.
Questioned on earlier figures that up to 50,000 new cases would be emerging by Waitangi Day - and 80,000 a day a few weeks later - Hipkins described the calculations as useful, saying it was better to have some modelling than none.
"They are useful. It's better to have some modelling than no modelling. It's a little bit like the weather forecast. Some nights they say it's going to rain tomorrow and it turns out being a nice sunny day."
Hipkins said people wanted to have confidence that the Government was mindful of what the future might hold and prepare accordingly.
"I think people do want to see that the government is at least generally finding what evidence we can for what the potential scenarios might be so that we can be prepared for that."
On Rapid Antigen Tests, Hipkins said people couldn't buy them at the moment due to global supply issues. Even countries that had been making them more freely available were being a bit more restrictive, he said.
"I think the global supply chain will resolve itself and we will see a much greater number of them but at the moment they're in short supply."
He said it was important that the Government ensured RAT tests were available for those who needed them the most. "The priority for us is going to be making sure we've got tests available to those who need to test in order to return to work."
On Sir Ian Taylor and the Kudu Spectrum deal - to bring tens of millions of rapid antigen tests into New Zealand - the Covid Response minister described him as a "good, critical friend" of the government.
Hipkins said the businessman had been working closely with the Government over an alternate supply of rapid antigen tests and he appreciated that.
Hipkins said the Government now had nearly 200 million tests on order but some of those weren't expected to arrive until later in 2022.
He said on criticism levelled against the government by Taylor about identifying essential businesses, a set of criteria would be released detailing which workers needed to go to work and which businesses were regarded as critical.
Businesses would then assess themselves against the criteria.
Hipkins said these businesses would be eligible for rapid antigen tests. "Every business is essential but some are more essential than others in an environment where you've got a big surge of Covid-19 cases in the community," said the minister.
Asked if there was anything that could hold off opening the border to people from the rest of the world in October, Hipkins told TVNZ's Breakfast show that he could not say.
"Well, we're still in a global pandemic so I can't give guarantees about what might happen in six months' time."
Hipkins said officials would be monitoring the situation over the next few months still.
"We'll become more normalised as time goes on."
Hipkins said the Government did consider how waiting until October to open up borders could impact the tourism industry.
But he acknowledged that many of our tourists at the moment come from visa-waiver countries and could therefore come in from the middle of the year.
On MIQ, Hipkins acknowledged it had been very difficult for Kiwis trying to return home. But he said those strict measures had helped to keep the number of Covid cases in the country down.
As a result, New Zealand had seen fewer Covid deaths and less time in lockdown in comparison to other countries.
Addressing concerns that Māori could be impacted more by opening up the border, Hipkins said there would be moves to encourage more Māori to get out and get vaccinated or boosted - including tamariki, he said.
Hipkins said he is due to speak with members of the Māori community about getting vaccinated.
The end of MIQ
After nearly 700 days and more than 220,000 travellers passing through its doors, Prime Minister Jacinda Ardern says it's the beginning of the end for our MIQ system.
A phased reopening of the border introducing self-isolation for arrivals would start from February 28, first with vaccinated Kiwis coming from Australia and critical workers, Ardern said yesterday.
Two weeks later Kiwis from the rest of the world could arrive MIQ-free, followed by other travellers in phases from July through October.
Two years ago, 741,574 people arrived over January. Last month just over 15,000 people arrived - less than the quietest day pre-Covid.
That has been the impact of MIQ, which Ardern said had been a huge part of the country's Covid-19 response that had kept it free of the virus for long periods, with one of the lowest death rates in the world.
But it wasn't without its costs, including heartbreaking stories of Kiwis and migrant families separated from loved ones, and for businesses and critical services struggling without vital workers.
Ardern said yesterday it was time for a "new normal" and, with rising vaccine booster rates and Omicron creeping through the community - the seven-day average has nearly tripled in the past week to 113 cases - an end to the need for MIQ as it has stood.
A Covid-19 modeller warns as the border reopens hundreds - if not thousands - of new cases will likely arrive daily. Currently, just under 10 per cent of all arrivals are infected with the virus.
However, with the community outbreak rapidly growing and likely to be in the thousands of cases daily when reopening begins at the end of the month, border cases will make less of an impact, Professor Michael Plank says.
Plank says with about 50 cases a day at the border that could quickly ramp up to 500 as arrivals increased.
Herald analysis of data from Customs and the Ministry of Health shows on average over seven days to February 2, 49 cases a day were detected at the border among 584 daily arrivals.
This meant 8.4 per cent of arrivals carried Covid-19, likely the highly infectious Omicron variant.
This proportion has risen rapidly, with border case numbers in the single digits in December and now nearly doubling from just over two weeks ago, despite similar arrival numbers.
"That is a very high percentage we are seeing at the border, but just reflects the massive number of cases we are seeing around the world," Plank said.
It would be expected as new arrivals increased so too would case numbers.
However, once the local outbreak took off these cases would make less of a relative difference, and the staged reopening also mitigated this risk, Plank said.
"The timeframe for the first reopening step on February 27 looks reasonable.
"By that time, it is likely daily case numbers will be in the thousands and the vast majority of vaccinated adults will be eligible for their booster.
"Self-isolation and testing requirements for arrivals will dampen the effect of border cases on community transmission, while removing the bottleneck of MIQ and allowing us to monitor for possible new variants."
Plank said high booster coverage was crucial to avoid overloading the healthcare system.
Te Pūnaha Matatini principal investigator Dr Emily Harvey said the testing requirements - a rapid antigen test on days 0/1 and 5/6 - in the new self-isolation system was also likely to miss a large number of infections.
Arrivals should use RATs daily, or at least every two days, and a more rigorous PCR test in case of any symptoms, she said.
National Party leader Christopher Luxon welcomed the border news, calling it a "good day for New Zealand".
National had been calling for an end to MIQ, which it dubbed a "lottery of human misery", since last year, although it backed the Government's delayed reopening because of Omicron.
Luxon said this was not about party politics but "the people of New Zealand".
"It is a positive thing and we are fully supportive.
"We all have family members overseas and it will be awesome to be able to reconcile."
It was also important for bringing in critical workers, he said.
Act Party leader David Seymour said the plan still contained a "huge amount of restrictions", and had not come soon enough.
"Now, having failed to do that, we've got Covid and we're in the No Man's Land where we have half a border, Omicron's in the country, the economy can't keep going."
Green Party spokeswoman for Covid-19 Dr Elizabeth Kerekere said as the country began to reopen, the most vulnerable needed to be put first, including properly resourcing Māori and Pasifika health providers.
The Government also needed to provide adequate support for households to create self-isolation plans and prioritise immunocompromised people and people with underlying health issues, she said.
Te Pāti Māori co-leader Debbie Ngarewa-Packer said the decision had favoured business and commerce over people.
The general vaccine rollout last year had implicitly disadvantaged Māori because of its age prioritisation, and now Māori were again behind in getting booster shots and for tamariki.
Ngarewa-Packer, who has trained as a vaccinator and has been working in her rohe around South Taranaki for months, said those working hard on the ground would be the ones having to bear the brunt of the Government's decisions.
"These decisions were not made for our most vulnerable," she said.
There were 147 new community cases of Covid-19 reported yesterday, with the seven-day average now 113, nearly tripling from 41 a week ago.
