A traveller on an 18-hour flight from Dubai to New Zealand who had tested negative for Covid-19, 48 hours before boarding the flight but ended up infecting at least four other passengers has once again highlighted the uncertain nature of testing for the novel coronavirus.
One person had arrived from India via the United Arab Emirates last Tuesday and the other had arrived from the USA last Thursday.
Both tested positive for Covid-19 as part of the regular day-three testing and have been moved to the Auckland quarantine facility.
There are 52 active cases of COVID-19 in New Zealand.
Using genetic sequencing, researchers determined they had the same strain of the virus, which was traced to Switzerland, the country of origin of the suspected initial case, the report said.
Air New Zealand On Monday, Air New Zealand made the Ministry aware of a possible case of COVID-19 in a staff member who is now in China.
"In conjunction with the company, the ministry will continue to investigate the circumstances of this possible case", the ministry said in a statement.
"The crew will remain in isolation while we work with Chinese authorities, New Zealand Ministry of Health and New Zealand Ministry of Foreign Affairs and Trade to make arrangements for their safe return home".
Locations the crew member visited in the relevant time period prior to departing on their flight are also being investigated, and anyone who went to pet supply store Animates Manukau on November 21 between 1.22pm and 2.11pm should get tested, the ministry said. All other crew members tested negative.
There were also brief visits to a number of other businesses and shops on 20 and 21 November.
