Today there was one new case in Christchurch. The person had recently travelled into New Zealand from overseas, a Health Ministry spokesman said.
They had multiple negative tests in MIQ in Auckland, including a day 12 test, before being released and travelling to Christchurch. They have reported as being fully vaccinated. On Thursday, they had a further test, which returned a positive result last night.
The person was now self-isolating, and further tests are being done to determine the source of infection.
"Because there are cases in Canterbury, it is important that anyone, especially those in Christchurch, with any symptoms, no matter how mild, please get tested," the spokesman said.
"Those in Canterbury are also reminded to get vaccinated today if they have not already."
All is tracking well in other bigger cities with Wellington's Capital and Coast DHB recording 92 per cent first doses and 79 per cent second doses.
But while the big cities are performing well, some smaller ones are being left behind especially some more provincial areas and DHBs with high Māori populations.
Tairawhiti on the East Coast is at just 78 per cent first dosed and is the worst-performing DHB in the country, with Northland just slightly ahead on 79 per cent and Lakes DHB in Rotorua on 80 per cent.
Overall, around 3.69 million Kiwis have had at least one dose of the Covid-19 vaccine, which is about 88 per cent of the eligible population.
Nearly three-quarters, 74 per cent or 3.11m Kiwis, have had both doses.
The Government has opted for a vaccine target that every district health board has to reach separately, rather than an overall figure for the whole country.
