• Partially immunised <7 days from second dose or have only received one dose: Eight cases / 3 per cent

The Ministry of Health said today's number of community cases was an important reminder to remain vigilant.
There were three things everyone could do to protect themselves and others from the virus.
They were: ensure you were up to date with vaccinations and boosters; wear a mask and remember they are still required in many indoor settings; and stay home and avoid others if you're unwell, isolating or waiting for the results of a Covid-19 test.
"A good rule of thumb is to wear a mask in indoor public settings as we know that mask use halves the risk of spread of Covid-19."
To date, 95.2 per cent of eligible New Zealanders have had two doses of Covid-19 vaccine and 70.8 per cent have been boosted.
Cases on the rise in some places
The release comes as cases, thought to be plateauing, are increasing in some parts of the country - including Auckland - and also on the same day as it was announced New Zealand's borders will fully reopen two months earlier than the Government initially planned.
Yesterday there were 7970 new cases in the community and 28 Covid-19 related deaths were reported.
The seven-day rolling average of community case numbers was 7420, down from 7746 last Tuesday.
Yesterday, Prime Minister Jacinda Ardern confirmed the full border reopening date would be bought forward from October to July 31, while speaking to a Business NZ lunch in Auckland.
The final part of the staged border reopening will open the country to all visa categories - including tourists, workers, families and students.
Ardern also said pre-departure testing would be removed from the July 31 reopening.
Education Minister Chris Hipkins says international students will be welcome back across the country's schools and tertiary institutions from July 31, with new criteria he says will close a "backdoor to residency" loophole.
New Zealand closed its borders in March 2020 when Covid-19 began to spread and a reopening plan only got under way this year.
Cases then declined to the seven-day moving average low point on April 19 of 1569.
