Mattina  

Health and border authorities continue to manage the situation around the Mattina.

The health and welfare of the crew are being overseen by Southern DHB’s Medical Officers of Health, who are working closely with maritime, port and other government agencies.

Last night, we confirmed the results of whole genome sequencing from nine crew members of the Mattina, showing they have the Delta variant of COVID-19. This morning, the Ministry can confirm that a further three crew members onboard have tested positive for COVID-19. In total onboard the Mattina, there are now 15 positive COVID-19 cases.

As we have indicated in earlier updates, all crew who have tested positive will remain quarantined on board the vessel at this time, where they will maintain the minimum functions at the port. They will not have direct contact with any port staff while maintaining these functions.

Three crew members, including the ship’s captain, who have all tested negative for COVID-19, have been safely transported to onshore facilities, under the same strict infection prevention and control procedures, including the use of full PPE, regularly used to transport people arriving from overseas to MIQ facilities.

The captain on the ship was safely transported last night to a secure DHB-provided facility to isolate.

Two of the other crew members are being transported to a Christchurch-based quarantine facility today.

These plans have been put in place to ensure the safety and wellbeing of the negative crew members at the same time as the health and wellbeing of members of the community. In both instances, the public health risk to the community has been deemed low.

Daily health and welfare checks are continuing for all crew members who remain onboard the Playa Zahara in quarantine in Lyttelton.

Four crew members remain in quarantine onboard the Viking Bay fishing vessel at Queens Wharf in Wellington. The crew members are continuing to be tested during their quarantine.

A comprehensive safety plan has been developed and the risk to port workers and the public is deemed low.

The remaining 16 crew members remain in quarantine in a Wellington quarantine facility onshore, with plans underway for those crew members who have completed their required 14 days of isolation to leave managed isolation.
