There are no new Covid-19 cases in the community - the Government says it will be going deep into Wednesday before making a call on the status of the country's alert levels.
As the country waits to see if the latest Covid-19 cases fizzle out or involve a super-spreader event, the suburb at the centre of the lockdown is hunkering down.
A strip of shops on Papatoetoe's Puhinui Rd near one of the locations of interest was quiet.
The country is waiting for the majority of test results from Papatoetoe High School - and with it, future of Auckland's snap level 3 lockdown and the rest of New Zealand's level 2 restrictions.
The Auckland family who have tested positive for Covid-19 - a mother, father and daughter - have what are considered 42 close contacts. Thirty-three of them are students and teachers from the high school and nine are non-high school close contacts.
At nearby Ranfurly Superette, a Ministry of Health location of interest, a staff member wearing gloves and a mask said she couldn't comment on the Covid-19 situation.
A neighbouring liquor store was open but people weren't allowed to enter and had to order at the door.
The quiet streets suggested people were heeding what infectious diseases expert Dr Siouxsie Wiles called a "circuit-breaker" lockdown.
She said a similar approach was used recently in Melbourne when the virus flared up in Victoria.
Circuit-breakers aimed to slow down transmission while authorities gathered more information about new cases and the nuances of the virus.
She said new Covid variants could lead a person to become infectious faster than the original virus variants.
It still wasn't clear how long people were incubating the latest UK variant for before becoming infectious.
"It's just the fact that there is potential for super-spreader events."
Some businesses around Papatoetoe resembled those of last year's nationwide level 4 lockdown.
At a local BP station, staff remotely controlled the door and people had to wait outside before being let in.
Another close contact of the Covid-positive Auckland family has tested negative - bringing to 12 the number of close contacts who have tested negative, director general of health Ashley Bloomfield said today.
Eleven of 42 close contacts returned negative tests yesterday, and a 12th - another school test - came back negative last night.
Wiles said a recent case in Perth highlighted the mercurial nature of the virus.
A hotel security guard contracted a UK variant on about January 24 and Western Australia went into lockdown.
Wiles said the Perth circuit-breaker was activated because many people were potentially exposed.
But Perth appeared to have avoided a super-spreader event or widespread community transmission.
Wiles said it was still largely unknown why cases like the Perth one ended up fizzing out while others, such as some Melbourne cases, proved hugely infectious.
Bloomfield told Newstalk ZB's Mike Hosking this morning that if all of the close contacts came back negative "that would reduce the likelihood" Covid-19 was widespread in the community.
But he wouldn't go so far as to say New Zealand would be in the clear. "We're not done, what we are is reassured that there hasn't been any onward transmission from our current cases. The other thing we're really looking for - because we're not sure exactly where this infection has come from - is are there any parallel sort of chains of infection or chains of transmission out there in the community.
"So the wider testing in the school, and in the workplace and the community, and in particular those places of interest is what we're really looking at as well."
Separately, seven of nine close colleagues of the mother - who works at airline food and laundry provider LSG Sky Chefs - have returned negative tests so far.
The mother is considered the most likely of the three family members to have contracted the virus first although that has yet to be confirmed.
Bloomfield said officials were keeping an open mind about the source of the infection because the daughter developed symptoms before the mother.
"The important thing about a source is keeping an open mind and not to jump to conclusions, just because the mother works around the airport precinct is not to say 'oh that's where it's come from'. One of the interesting things here is that the daughter reported onset of symptoms before the mother. So we have to be open-minded that she could be the first case, and could have got it somewhere else. And that's what we're trying to track down."
Onward spread and whether the source of the infection has been found - or narrowed - would be the key things Bloomfield will be looking at when he writes his advice for Cabinet tomorrow on alert levels. "By the end of the day we'll certainly have a lot more information."
More than 3000 people were tested yesterday and the bulk of those results would come back today.
Those results will help determine if Auckland's lockdown is a short, sharp affair - perhaps over as early as tomorrow night - or whether the country is dealing with a bigger community outbreak of Covid-19.
Health experts are still striving to pinpoint the source of the UK variant which has infected the Auckland family.
Hundreds of people were tested at a pop-up testing station at the school yesterday. The school's principal, Vaughan Couillault, expects 3000 tests to be administered over Monday and today, and urged patience for those waiting up to two hours in line.
News yesterday of no new active Covid-19 cases connected to the family came as "heartening" news to Prime Minister Jacinda Ardern but she is waiting until today's mass-testing results before she gets too comfortable.
"We do want to give it that bit more time before we get too far ahead of ourselves," she said last night.
Bloomfield was also pleased, saying yesterday's reported Covid numbers were an "encouraging sign".
But, like Ardern, he will be keeping a close eye on today's test results – particularly those from the school – before he gets too excited. "It is the days ahead that will be crucial."
Bloomfield disagreed - if the mother did prove to be the source - that the case highlighted ongoing issues at the border.
"She was as quite at arm's length from the border and she isn't actually captured by the current border order," he told Hosking. "Some of her work colleagues are, but she doesn't have any interface with passengers or people who are who are actually on the airside."
Even if she wasn't the source, "we're having another look at the testing around the border and that's exactly how we roll with these things. We learn and we adjust as we go".
Bloomfield said daily saliva testing was now starting to be trialled across quarantine facility staff. This was an "adjunct to the current genome PCR testing".
"So we may well introduce that, it's more pleasant for people than having the nasal swab. So, so far, the PCR testing has been and for time being will remain the mainstay."
Meanwhile, for the most part, Ardern said Auckland's first day back at alert level 3 had gone "smoothly".
This is despite some reports of long lines of cars with people waiting to be tested – some as long as two hours.
On Sunday, Ardern announced Auckland would go back into alert level 3 until at least Wednesday at 11.59pm. The rest of the country would be at level 2 over the same period.
Ardern confirmed yesterday there had been no changes to the alert level settings but did reveal the new community cases were the more infectious UK strain.
Bloomfield said this was a "tumultuous period" for New Zealand and that "Covid-19 can feel like being on a roller coaster that you haven't actually bought a ticket for".
But both he and Ardern were upbeat about the latest vaccine developments.
The first batch of roughly 60,000 Pfizer Covid-19 vaccines arrived on New Zealand shores yesterday morning.
Ardern said this would be "more than enough" doses to vaccinate New Zealand's frontline workforce over the coming weeks.
From here, smaller batches will continue to arrive while the newly arrived vaccines are tested for "quality assurance".
Ardern, however, remains confident the first jabs will be administered this Saturday. By then, the plan is for Auckland to be out of level 3.
But there are still a number of hurdles to overcome.

There were 2800 tests reported yesterday, mostly taken from Sunday when the three community cases were discovered.
Many more tests were taken yesterday and these would help provide a more accurate picture of the situation on the ground in Auckland.
Bloomfield will be keeping a close eye on the results of the tests taken at Papatoetoe High School, where one of the three new community cases goes to school.
"What we really want is the results of this testing at the school, at the workplace and in the wider South Auckland community to really rule out that there isn't undetected trains of transmission," Bloomfield said.
Ardern said there was "no doubt" that having some of the close contacts return negative results was "heartening".
"But I think all of us want a wider set of tests; we want to really rule out with some confidence additional potential chains of transmission and anything further in the community."
Despite this, she said she couldn't help but reflect on previous experience, looking at Auckland's August lockdown.
Back then, when the first positive cases were reported there were a number of other positive tests which sprang up at the same time.
That does not seem to be the case this time around, but Ardern warned more time is needed to get a fuller picture.
And although Ardern said the first day of the new lockdown went "smoothly," there may be a fair few Aucklanders who disagree.
Just hours after the new lockdown was announced on Sunday night, crowds of people flocked to the shops, despite Ardern saying that supermarkets would be open during level 3.
"It's just so clear that, after repeated attempts, there is something about human behaviour that says when restrictions are in place people will immediately feel the need to buy toilet paper, and I cannot explain it," she said.
Meanwhile, National leader Judith Collins has raised questions about the testing regime of those working in proximity to the border.
Yesterday, it was revealed that the now infected LSG Sky Chefs worker missed a Covid-19 test as she was on annual leave.
She tested positive after she came forward following feeling symptomatic.
It is the responsibility of the business which employs frontline staff to ensure they have regular tests.
National's Covid-19 response spokesman Chris Bishop said his party wants to see the rules changed so that any frontline staff are tested regularly, no exceptions.
He also wants the audit processes of companies employing frontline workers to be "tightened up" and for all of these firms to be using the same systems as the Ministry of Health.
