The number of new community cases of Covid-19 has jumped after several days of falling numbers, with 20 new cases reported in Auckland today.

There was no media conference today. In a statement, the Ministry said 19 of these are household or known contacts and only one of these remains unlinked.

"Interviews are underway with that person to determine how they are linked to the current outbreak."

There are now seven unlinked cases from the past 14 days.

The number of new cases has been slowly falling for the past few days, with 11 new cases reported yesterday and 13 on Thursday.

The Ministry said it was expecting some fluctuations in case numbers at this point in the outbreak.

There were also two new confirmed cases and two historical cases in managed isolation.

The Minsitry said testing at high levels in Auckland remained an essential part of the outbreak response and it was continuing to urge anyone in Auckland with cold or flu symptoms - no matter how mild - to get tested.
