Another worker at the Grand Millennium managed isolation facility has tested positive for Covid-19.

The Ministry of Health confirm that the new case is a close contact of the case reported on Thursday.

The worker in question has now moved to an Auckland quarantine facility.

'Because the new case has been self-isolating at home since being identified as a close contact late last week, there is considered to be very little additional risk to the community,” says a MOH statement. 'They returned an earlier negative test before returning a positive test today.”

Whole Genome Sequencing

The results of whole genome sequencing for the case reported late on Thursday have now been received and show a genomic link with a cleaner at the Grand Millennium who tested positive for Covid-19 on March 21 and has been previously reported.

The cleaner, known as Case A, and the worker who tested positive last week, are genomically linked to a returnee who arrived back in New Zealand on March 13.

'Due to this genomic link with the cleaner, Case A, the worker who tested positive last week will be known as Case B,” state the MOH. 'The investigation into how COVID-19 was transmitted to Case B is ongoing. Today's new case will be referred to as Case C.”

Locations of interest update

Case investigations are continuing, and further locations of interest are being confirmed.

Early indications are the majority of these contacts will be considered casual only.

Details of these locations and information for people who visited them during the relevant timeframes will continue to be updated on the MOH website.

The Ministry will also send out push notifications to people who logged on with the Covid Tracer app at any locations of interest.

The alert will advise users that they may have been in contact with Covid-19 and direct them to additional information on the website here Covid-19: Contact tracing locations of interest.
