An Air New Zealand spokeswoman said, as with all airlines, it followed public health recommendations regarding unwell passengers to prevent others being put at risk.
"For all international flights, should a customer present at check-in or at the boarding gate with symptoms of a communicable disease such as coronavirus, we have robust medical clearance processes to assess whether a customer is fit to travel. Likewise, there are clear procedures to contain the spread of infectious disease inflight and on arrival."
She said ground and cabin crew were are being updated regularly on the situation as it evolved and staff were being reminded of the best ways to protect themselves from viral respiratory infections.
"As standard procedure, our international aircraft carry medical and protective equipment to help contain the spread of infectious disease. We are ready to action further measures if and when needed," she said.
The airline operated one daily return service to Shanghai. There had been no impact on its schedule or any flight cancellations as a result of coronavirus.
Savage said that at the moment the situation does not appear to be worse than the Sars virus. That hit in 2003 and claimed close to 800 lives.
It was important for people not to panic, he said.
