There have been a total of 29 Omicron community cases in New Zealand to date associated with the January Omicron cluster. All of the cases are currently isolating.
Of these cases, there are 12 in the Nelson-Tasman, 11 in Auckland, three in Manawatū-Whanganui, two in the Bay of Plenty and one Air New Zealand flight attendant whose location was not disclosed.
Nelson-Tasman
The nine people who tested positive for COVID-19 in Motueka were confirmed as Omicron cases on Sunday.
Prime Minister Jacinda Ardern announced the country will move to the red traffic light system at 11:59pm that night after these cases had an initial estimate of over 100 people exposed.
The cases, who are all from the same family, flew to Auckland from Nelson on January 13 to attend a wedding and other events over January 15-16.
The cases attended a wedding at the Totara Event Centre in New Lynn on January 15.
A second wedding on January 16 at the Pukekohe Indian Community Centre has been linked to an Omicron case.
The cluster led to an additional infection of a fully vaccinated Air New Zealand flight attendant who was infected on their flight back to Nelson on January 16.
Two more cases were confirmed on Monday, both are contacts of the existing cases.
Another case was confirmed on Tuesday that is a household contact of a previous case and was already isolating when they tested positive.
Auckland
Six Omicron cases in Auckland were reported on Tuesday, all cases have been indirectly or directly linked to a family event and other associated events on the weekend of January 15 to January 16.
These cases join the five Omicron cases reported in Auckland on Monday. All are also linked directly or indirectly to one of the reported family events the Nelson/Tasman cases attended.
Manawatū-Whanganui
A third case of Omicron has been reported in Palmerston North on Tuesday, a household contact of a previous case, and has been in isolation since before they became infectious.
This follows as a second case was reported on Monday after the first case was confirmed in the region on Friday, a person who had recently been in MIQ.
The first case was released from a MIQ facility in Christchurch on January 16 after returning five negative tests during their stay. They believe to have been infectious since January 17 and visited a range of shops listed on the Ministry of Health website.
The case got tested on Wednesday 19 and received a positive result that evening, but the case was not officially confirmed until Friday 21.
Bay of Plenty
Omicron hit the Bay of Plenty on Tuesday, with the first-ever two cases of the variant reported in Tauranga.
At this stage, the Ministry of Health said investigations are underway to determine how the pair were exposed to the virus but said "at this stage, there are a limited number of exposure events associated with these cases".
Both cases are from the same household and are isolating at home.
