"We are an important step closer to Auckland transitioning to the new traffic light system which means restrictions will ease once each DHB is 90 per cent second dose," Covid-19 Response Minister Chris Hipkins said.
That dose mark could be reached as early as the end of the month - three weeks from now when the most recently vaccinated people are due to get their second shots.
Yesterday Prime Minister Jacinda Ardern signalled that Auckland would likely move to the new system even if it is a fraction short of 90 per cent fully vaccinated after the Cabinet reviews progress on November 29.
"Everyone wants restrictions eased as soon as possible. We need to keep going and get those final second doses so we can ease restrictions with high rates of vaccination and high levels of confidence," Hipkins said on Sunday.
With the traffic lights likely to appear in December, there will be increased interest in the practicalities of the system. There is a lot of detail people will need to know.
That's especially the case with how the vaccine passes will work. Will there be teething problems? How easily will people and businesses adjust to using them? People will have to get used to differences when out in public depending on where the certificates are used or not.
With vaccination rates slower in most areas of the country, Auckland will most likely get to grips with it first. Ardern said six DHBs have hit 90 per cent first doses mark.
There's an approaching deadline to get it right. As yet there is no reopening date for the Auckland border.
Epidemiologist Professor Michael Baker said case numbers had to stay as low as possible before the expected shift.
"I think we are in the world of trade-offs now, where we are looking to have greater freedoms particularly for people in Auckland, but inevitably it will result in accelerating the outbreak.
"If we hit December with high transmission rates it might put more pressure on that move."
In another milestone, the significant goal of 90 per cent of the eligible population nationwide getting a first dose is being knocked off.
It was sitting at 89 per cent, according to Ministry of Health data. And the second part of that achievement is getting closer - 78 per cent of those able to get a dose are fully vaccinated.
The vaccination figures look less impressive as a percentage of the overall population with 75 per cent of Kiwis having had one dose and 66 per cent two. But it is similar to the levels of vaccination in the UK (74 and 67 per cent) and France (76 and 68 per cent), according to ourworldindata.org.
It's important to tick off these big picture developments even as underlying details are studied and questioned.
It bolsters confidence that we can make progress and reach the goals we have to.
