Coronavirus: Contacts of Tonga case isolating in Wellington, eight resthome infections, four in Northland

With 160 cases in the community, Saturday marks New Zealand's highest daily count of COVID-19 infections so far in the pandemic.

But beyond that headline figure, there's quite a bit to unpick in the latest COVID-19 update.

To start, there are reported cases across four New Zealand regions - 151 in Auckland, seven in Waikato, one in Northland and one in Canterbury. 

There's actually been four new cases in Northland over the last 24 hours. The Ministry of Health is only reporting one on Saturday as another was included in Friday's numbers - as an Auckland case which has now been reclassified - while the ministry only became aware of two others after Saturday's 9am cut-off mark. Those two cases will be added to Sunday's tally.

The new case in Christchurch is a fully vaccinated person who travelled into New Zealand from overseas, spent time at a MIQ facility in Auckland, had "multiple negative tests", including a day 12 test, before being released and travelling to Christchurch. The ministry says they had a test on Thursday which came back positive on Friday night. 

"The person is now self-isolating in Christchurch, pending further tests to determine the source of infection and whether it is acute or historical," the Ministry of Health says.

"Because there are cases in Canterbury, it is important that anyone, especially those in Christchurch, with any symptoms, no matter how mild, are asked to please get tested. Those in Canterbury are also reminded to get vaccinated today if they have not already."

It was also revealed on Friday night that a case in Tonga was someone who had left Christchurch for the island nation on Wednesday. They had a negative test before leaving Aotearoa and are fully vaccinated.

The ministry said on Saturday that four household contacts of this person have been identified. Two remain in Christchurch, while two others travelled from Christchurch to Wellington on Tuesday. 

"All contacts have been contacted by public health officials, been told to self-isolate and get tested."

"Anyone with symptoms is asked to please get tested and reminded to get vaccinated today if they have not already. Testing locations in the Wellington region can be found at Capital and Coast DHB and Hutt Valley DHB."

In Auckland, after a resident at Henderson's Edmonton Meadows retirement village was reported on Friday as having COVID-19, it's now been revealed an additional seven residents and a staff member have also tested positive. 

"It’s important to note there are high levels of vaccination among residents of the home, and all staff are fully vaccinated," the ministry says. "All staff and residents have now been tested and will also receive day 5 and day 12 testing.

"Auckland Regional Public Health staff are supporting the residents and staff at the privately-owned facility.

"At this stage, only one positive staff member has been required to stand down.

"The retirement village has been operating under alert level 3 guidelines for visitors, meaning people have only been able to visit the village on compassionate grounds."

There's also a specific focus on the suburbs of Redvale, Rosedale, New Lynn, Wiri, Drury, Henderson and Manurewa in Auckland, with officials wanting anyone here with symptoms to get tested, no matter how mild those symptoms may be or if they are vaccinated. 

Of the seven Waikato cases, two are in Kawhia (they were mentioned on Friday but are being recorded in Saturday's update), three are in Hamilton, one is in the Te Awamutu/Kihikihi area and one is in Ōtorohanga.

"Public health investigations have so far determined links for two Hamilton cases and the Te Awamutu/Kihikihi case. Investigations are continuing today to establish further links for the remaining four. All are in isolation with public health oversight."

The Ministry of Health says the high number of cases being recorded are "a reminder of the infectiousness of COVID-19, and particularly the Delta variant, and the importance of vaccination as the best protection".

"The rise in case numbers is not unexpected and is in line with modelling to date."
