*SO/Auckland Hotel MIQ worker update

After further investigation, including retesting, the positive COVID-19 test result returned by the SO Hotel MIQ facility worker last week has been determined to be a false positive.

The individual has been notified and will be able to be released from the quarantine facility today.

The Ministry of Health would like to thank the person for their cooperation.

As a result, the net increase in community cases today is 21.

*Whakatīwai cases

The three cases recorded in Whakatīwai fall within the Counties Mānakau DHB catchment and are being counted in the Auckland total.

*Sub-clusters

The number of epidemiologically linked subclusters now sits at ten. The new one is associated to two households in South Auckland.

Unlinked cases

Of today’s 22 new community cases, 17 are linked to known cases.

Of the five unlinked cases today; three are from one household; the other two are being interviewed.

Of the 22 new cases today, 10 were already in quarantine when they were tested.

Whole genome sequencing

ESR has now analysed whole genome sequencing from samples taken from several recent cases. This shows the truck driver and a couple who went to Middlemore Hospital with COVID-19 symptoms are genome linked to the main outbreak cluster.

Wastewater testing

Following confirmation of the three cases in northern Hauraki, ESR is currently sampling from Kawakawa Bay and Pukekohe. Samples are being collected from three sites in the region. In addition, new samples are being collected from Cambridge, Ngatea, and Paeroa. Results are expected later in the week.

Seven suburbs of interest

Testing in the seven suburbs is continuing with 946 tests taken yesterday across Mt Eden, Massey, Māngere, Favona, Papatoetoe, Ōtaraand Manurewa.

The Ministry has asked people in these areas, both with symptoms and without, to get tested to help rule out undetected community transmission. Today we are asking in particular for anyone living in Clover Park, on the south east side of Papatoetoe, to please get tested.

Testing in Kaiaua

There has been a good community turn out for testing in Kaiaua this morning. By 11am today, 150 swabs had been taking. The Waikato DHB has reported wait times of about 30 minutes.

Further update

There will be a further update on the latest cases this afternoon.
