There is one new case of Covid-19 today - the first reported this week.

The Ministry of Health says the case has been linked to the St Margaret's cluster in Auckland, and was a household contact of an earlier case.

The person was already in isolation because of their connection to the earlier case.

A spokesperson for the Ministry says this is another example of the long tail of Covid-19.

Today's new case brings New Zealand's total number of confirmed cases to 1154.

Our combined total of confirmed and probable cases is 1504.

Ninety-seven per cent of all confirmed and probable cases have recovered, the ministry says.

No additional deaths have been reported, which means the death toll remains at 21.

One person remains in hospital, they are at Auckland's Middlemore Hospital in the intensive care unit.

Yesterday, 5408 tests were completed bringing the total number of tests to 250,246.

New Zealand's new Covid Tracer app has now recorded 294,000 registrations.

The Ministry says officials continue to encourage as many people as possible to download the app. It will help us identify, trace, test and isolate any cases of Covid-19, a spokesperson says.

"The faster week can do these steps the less likely it is the virus can spread in our communities."

As New Zealanders head into the weekend, the Ministry wanted to remind people that the maximum number of people who can gather remains at 10 for now.

That applies to both private and public gatherings including church and faith-based events, they said.

Funerals and tangihanga were the only exception, and had to be registered by funeral directors with the Ministry of Health.

Director general of health Ashley Bloomfield he knew many people would meant to move as quickly as possible to increase the size of gatherings and he knew how important it was for people to be able to practice their faith together.

"As we head into the weekend, I want to acknowledge that once again the support and patience of New Zealanders right through level 3 and 4."

"The number of people at gatherings will be one of the specific issues being reconsidered by Cabinet on Monday."
