An Air New Zealand flight from Bali to Auckland was diverted to Australia this morning following a medical emergency on board.

Flight NZ246 touched down in Darwin to allow two passengers to get off, after one reportedly had an allergic reaction.

Another passenger on board the plane said a woman "had a very severe reaction to some medication", and the flight attendants gave her oxygen before the aircraft landed in Darwin.

"Crew, as expected, very calm and professional," he said.

Air New Zealand confirmed there had been a "medical incident on board".

"Two passengers remained in Darwin and the aircraft continued to Auckland," a spokeswoman said.
