There are no new cases of Covid-19 in New Zealand today, the Ministry of Health has confirmed.

Three people are in hospital with Covid-19, one each in Middle, North Shore and Auckland City hospitals.

The total number of active cases is 61, 32 of those are community cases. That brings the total number of Covid-19 cases in the country to 1446.

There have now been a total of 917,699 Covid-19 tests processed.

Director-General of Health Ashley Bloomfield says it's important we all remain vigilant, monitoring our health and not going out if symptoms appear.

In the instances of people who have since recovered from Covid-19 the test comes back positive with a high CT count - a weak positive result, he says.

There are four groups of people this covers, including the people who tested positive overseas after coming from New Zealand.

A protocol is being developed to work on how these cases are managed, he says.

Dr Bloomfield says these historical cases are not infectious.

He says the key thing about the testing plan is that anyone anywhere in the country with symptoms should be tested.

There were no new cases of Covid-19 in the country yesterday.

Auckland has operated at tailor-made "alert level 2.5" since 31 August. The city will move down to level 2, with eased restrictions on gatherings, at 11.59pm on Wednesday.

That level will be in place for 14 days, with Cabinet set to review those settings again on 5 October.

The rest of the country has moved down to alert level 1 today but there is still a risk of Covid-19 returning to the community, according to the Ministry of Health.
