This is the final data Cabinet will consider before its meeting today to decide on alert levels.
Prime Minister Jacinda Ardern and director general of health Dr Ashley Bloomfield will then hold a press conference at 4pm to explain the numbers and reveal a roadmap for Auckland out of lockdown.
Twenty-eight are in Auckland and one is in Waikato.
Eight of today's cases are so far unlinked to existing cases and investigations are ongoing.
The remainder were in isolation during their infectious period.
Overnight three household contacts of the Raglan case tested positive for Covid-19 – one of which is a newly identified household contact.
All have now been moved to an Auckland quarantine facility. These will be officially recorded in tomorrow’s case numbers.
Meanwhile, initial tests from all four close contacts associated with worksites of the Auckland-based truck driver, who is isolating in Palmerston North, have returned initial negative results.
More than half of yesterday's 33 cases (19) were infectious in the community and have exposure events linked to them.
There are currently 30 cases in hospital and 5 of these are in ICU.
There have been no unexpected wastewater detections in the last 24 hours.
In total, there are 1184 contacts being managed as a result of these outbreaks.
The new cases mean the national total for Covid-19 cases since the very start of the global pandemic is now at 4025.
Yesterday there were 27,033 vaccine doses administered, of these 7041 were first doses and 19,992 were second doses.
In total throughout New Zealand, there have been 5,346,591 doses given out; 3,328,286 are first doses and 2,018,305 are second doses.
With these numbers we have now passed the two million mark for second doses of vaccine administered.
"This is a really pleasing milestone and we want to reiterate our thanks to everyone who has so far had either their first, or second vaccination. Vaccination continues to be one of our strongest defences against Covid-19, " the Ministry of Health said.
Earlier today
So far today it has emerged that a baby has tested positive at North Shore Hospital and an Auckland taxi driver may have been infectious for two nights carrying passengers. Taxi drivers are legally required to wear a mask in level 3.
Ardern also confirmed there are more household infections relating to the Raglan case revealed yesterday.
Several public health experts have said that announcing a move to level 2 for Auckland this week would be too risky, given the relatively low vaccination rates there.
But Ardern is expected to say what aspects of alert level restrictions are lower risk and could be brought in for Auckland, as well as how the vaccination rollout can be boosted.
The trend in cases - including unlinked cases - in Auckland has been rising in the past week. Yesterday there were 33 cases, which only included one of the two Waikato cases, and 23 of them in the past fortnight were unlinked.
This morning Ardern said the household contacts of the Raglan case have tested positive.
Genomic sequencing has linked the two Waikato cases to the Auckland outbreak, but an epidemiological link - who they caught the virus from - remains unclear.
A baby in North Shore Hospital, the parent of a baby in Auckland City Hospital, and an Auckland taxi driver have also tested positive since yesterday's update.
New locations of interest include a BP station and a sushi place in Raglan, and a Burger King in Palmerston North, following a truck driver who travelled from Auckland to Palmerston North testing positive.
This morning Ardern said there were other options than simply moving Auckland to level 2, and ministers had been considering which lower risk aspects of the alert levels might be introduced for Auckland.
She also said that high vaccination rates provided more options than chasing elimination.
She has not set any official vaccination targets, but yesterday she said that 90 per cent coverage of the eligible population would have meant the five-day level 3 restrictions may not have been needed in the Waikato.
Asked whether that meant the elimination strategy was at an end, she said: "We're in a transition. So we are changing our strategy as we move. We still need to control this outbreak but we are transitioning."
Just under 79 per cent of eligible New Zealanders have received at least their first jab, while the rate in Auckland is just under 84 per cent.
Five days at level 3 for parts of the Waikato started at midnight last night, though there was some frustration due to a boundary map only being released overnight.
The two Waikato cases, based on information so far, have not travelled outside the region, though there are some 5000 to 7000 people from outside the Waikato that visited the region during the five days that at least one of them were considered infectious.
Ardern said yesterday that she had not seen any need to put all of the North Island into level 3 at this stage.
She also all but ruled out putting Auckland back into level 4, adding that part of the moving Auckland to level 3 in the first place - described as a calculated risk by public health experts at the time - was because of the public's weariness of level 4 and the possibility of rule-breaking creeping in.
