There are no new cases of Covid-19 in the community, but there are two new cases in managed isolation today.

The two cases in managed isolation are from the Philippines and Pakistan.

Meanwhile, flights to and from Sydney as part of the transtasman travel bubble are set to resume tonight.

"Public health officials have assessed that the situation in Sydney, following two community cases reported earlier in the week, is contained and there is no evidence to suggest widespread, undetected community transmission," a ministry spokesperson said.

Officials advise anyone who was at a location of interest in Sydney at the relevant times must follow New South Wales health advice regarding isolation and testing.

They must not travel to New Zealand within 14 days from when they were at the location.

Travellers who have arrived in New Zealand and have been at a location of interest during the exposure time must immediately self-isolate.

They should call Healthline on 0800 358 5453 for advice on when they should be tested.

A direction has been issued under the Health Act enabling an authorised Medical Officer of Health to require those affected to undergo testing and to isolate until they receive their result.

Information about locations of interest can be found on the New South Wales health website: https://www.health.nsw.gov.au/Infectious/covid-19/Pages/case-locations-and-alerts.aspx 

Health officials are also investigating the deaths of two New Zealanders in their 80s who have died since having the Pfizer/BioNTech Covid-19 jab under "an abundance of caution".

Officials have stated there is currently no direct link to the vaccinations.

The Ministry of Health says it has been made aware of the deaths and "through an abundance of caution" it is investigating fully.

Medical staff believe the deaths are not related to being vaccinated.

"Our sincere sympathy to their families and friends who are grieving their loss," a Ministry of Health spokesperson said.

Both deaths have been reported to the Centre for Adverse Reactions Monitoring.

The process includes Medsafe "closely" monitoring all reports.
