Scientists are waiting for a sample from the Air NZ crew member who tested positive for Covid-19 after a flight to China.
The crew are due back in New Zealand this morning, and will be isolated and re-tested.
The crew member tested negative before leaving on the trip, but tested positive once the plane had arrived in Shanghai.
Dr Jemma Geoghegan, a virologist at Otago University, says she and other researchers are eager to get a sample to help identify the strain of virus involved.
She speaks to Corin Dann.
