There are 43 new cases of Covid-19 in the community today.

Figures supplied by the Ministry of Health show 40 of those are in Auckland and three in Waikato. There are three new cases at the border including one historical case.

All three of the Waikato cases were known contact and were already in isolation

Of today's new community cases, 24 are epidemiologically linked and 19 are yet to be linked - interviews are ongoing to determine links.

There are 74 unlinked cases from the past 14 days.

In addition, there are 16 epidemiologically linked subclusters. Of these, five are active, one is contained and 10 are dormant. There are also 14 unlinked subclusters. Of these, five are active, zero are contained and nine are dormant.

There have been no "unexpected" detections of Covid-19 in wastewater sampling in the past 24 hours.

The number of active contacts being managed is 2261. Of these, 77 percent have received a call from contact tracers to confirm testing and isolation requirements. In addition, 75 percent of them have had at least one test.

There are also 34 people in hospital including five in ICU or HDU.

The previously reported Bay of Plenty case has been reclassified as not a case and removed from the case count.

Fifty-eight percent of people infected with Covid-19 in the latest outbreak have not been vaccinated.

Only 4 percent had received the full dose more than 14 days before being reported as a case.

Of those who ended up in hospital, 21 percent were children under 12 who are not eligible to be vaccinated; 124 people over 12 out of a total of 158 individuals had not had any vaccination.

Of the 158 people hospitalised since the start of the outbreak shows only three people were fully vaccinated with 14 days passed to give them full immunity.

A total of 16,565 tests were taken in the past 24 hours and 13,981 were processed.

There were 15,107 first doses of vaccine administered yesterday and 54,011 second doses.

Northland case

Director-General of Health Dr Ashley Bloomfield says the Northland case and their travelling companion are both in MIQ in Auckland.

There are 18 close contacts associated with the original case and of these 17 have been contacted, tested, and are isolating. The remaining person is being "actively followed up by our contact tracers".

The whole genome sequencing for the case who travelled to Northland shows a link to the Auckland outbreak.
