There are five new cases of coronavirus in New Zealand, the Ministry of Health said on Sunday, four of which were detected in the community.

The remaining case was in an Auckland managed isolation facility, the Ministry said.

New Zealand's latest COVID-19 figures were announced in a press release on Sunday afternoon.

The four community cases are all linked to the Auckland cluster, while the imported case is a man in his 20s who arrived from India on August 23. He tested positive on day three of his stay and is now in quarantine.

As of Sunday afternoon, there were 72 people linked to the Auckland cluster staying in the Jet Park Hotel - the city's quarantine facility - 58 of whom have tested positive for COVID-19.

There are four people in hospital with COVID-19; two in North Shore, one in Middlemore, and one in intensive care at Waikato Hospital.

A Ministry of Health spokeswoman said one additional case has recovered in the past 24 hours, bringing the number of active cases nationwide to 116 - 77 in the community and 39 in managed isolation.

The five new latest cases bring the country's total to 1421.
