Air New Zealand has stood down cabin crew from three flights after a passenger was found to have been infected with the Covid-19 coronavirus.
The airline said the crews would also be self-isolating for a fortnight as a precaution.
It comes after a woman travelled from Milan to Singapore on Singapore Airlines and then on to Auckland in February on Air New Zealand.
She took an internal flight to Palmerston North and back to Auckland a week later.
Her diagnosis was confirmed on Tuesday night.
A spokesperson for the airline said it was updating staff regularly and giving them information on best ways to protect themselves.
Singapore Airlines also asked pilots and cabin crew who were on the Milan-to-Singapore flight with the woman to take leave.
