There are 92 new Covid community cases on day one of the nation's move to the new traffic light system.
The last day New Zealand recorded under 100 community cases was October 28, with 89 cases.
Of today's cases, 80 are in Auckland, two in Waikato, one in Northland, five in the Bay of Plenty, one in Lakes DHB, one in Nelson-Marlborough and two in Taranaki.
There are now 936 people with Covid in isolation in their homes.
The Government had also sent out 54,500 temporary exemption emails to people who had trouble downloading their passes.
87% of target population fully vaxxed
Deputy PM Grant Robertson said the nation heads into the new traffic light system with high vaccination rates: 93 per cent of eligible people have had one dose and 87 per cent have had both doses.
Robertson said the high vaccination rates showed a unified New Zealand, rather than a divided country as some people had tried to portray it.
Robertson said the Government and its partners had changed the way they were targeting unvaccinated people.
He said setting up a "static" place where people could come to be vaccinated did work any more. Instead, vaccination clinics needed to be mobile and go to where the unvaccinated people are.
McElnay said the new style of promoting vaccinations was working, and the Northland first dose rate had now hit 86 per cent.
Two more DHBs hit 90% target
Waitematā and Canterbury DHBs are now the third and fourth DHBs to hit 90 per cent double-jabbed with the Pfizer vaccination.
Robertson said of the five DHB regions yet to hit the 90 per cent single dose mark, Lakes DHB is just 785 doses away, and the West Coast only 284 doses away.
Robertson said this will be the last Friday 1pm press conference of the year. There will be more 1pm press conferences next week, but no more on Friday this year.
When asked why there are still glitches and problems downloading My Vaccine Passes and rules under the traffic light system, Robertson said it is complex to work through setting so many rules for every business.
He said councils run public facilities but they do have the ability to make their own decisions about whether those accessing their services need to show My Vaccine Passes or not. He just asked that they communicated their requirements to the public clearly.
'No cause for alarm' in Nelson
Robertson said there had been excellent testing numbers in the Nelson region - about 1400 yesterday - and that meant officials were confident the virus was spreading as expected in the area.
McElnay said the public health unit in Nelson was working closely with the school and businesses affected in the area.
"It is hard to say whether we will get more cases," she said. "But at this stage we have no particular cause for alarm."
The Nelson region will remain at the orange traffic level; a move to red is not on the cards at the moment.
But Robertson said people with Covid symptoms are tending to go for tests quite late after getting symptoms. He urged them to get tested earlier.
Robertson said police will be working with iwi at Northland checkpoints to monitor people coming into the area.
However, he emphasised they are police checkpoints, set up and manned by police.
Omicron variant
Robertson said the Government doesn't at this point have any advice that the Omicron variant would require a new system for managing Covid.
However, if new advice came through that showed it was more serious, officials would act on that, he said.
McElnay said it did appear the Omicron variant is seemingly more infectious but studies were ongoing to see whether it caused more serious illnesses and whether it can infect fully vaccinated people easier.
Health teams are constantly reviewing what is happening around the world, McElnay said, and will in particular check on Monday how the Omicron variant is travelling in South Africa.
She said there had been a lot of sharing among the scientific community and she was on the phone with colleagues in Australia and South Africa yesterday.
This meant officials could keep an eye on whether South Africa should be deemed a high-risk nation for arriving travellers.
Luxon's call for green light in Auckland
Answering calls by National Party leader Christopher Luxon to put Auckland in the green traffic light system, Robertson said the Government had always moved cautiously.
And the "proof is in the pudding" that their actions had worked given by the low infection and death rates in New Zealand, he said.
He rejected criticism that the traffic light system is complicated. However, he understood it was new and people would still be getting used to it.
Robertson said it was possible Auckland could move down to a lesser traffic light level before Christmas, but he couldn't pre-empt the decision and it would only be known closer to December 13.
Regular customers Isabelle, Alan and Steve said it was fantastic to be back to their usual spot.
"We'll definitely come here and help the business. We feel for the cafe," Alan said.
Some people hit the town at the stroke of midnight, when some Auckland pubs decided to open their doors.
Headquarters bar owner Leo Molloy told Three's AM Show about 50 to 80 people came into the bar within the first 40 minutes of opening last night.
About 350 people had booked in for lunch and he expected a further 300 people as walk-ins.
Asked if anyone without a vaccination pass tried to get in, Molloy said only one person was turned away because they had an overseas vaccination pass, which was not accepted.
New system a step into the unknown - Professor Shaun Hendy
But as restrictions are reduced, the reality of Covid is still there and people are reminded to continue to stick to the rules and take safety measures.
Covid-19 modeller Professor Shaun Hendy says the move into the traffic light system today indicates a change in response - and only time will tell just how effective it will be.
"It's a step into the unknown," he told Breakfast.
"It takes us back, really, to March 2020 when the alert level system was put together. We're just going to have to watch, I think, over the next few months.
