Air New Zealand has announced it will suspend its Auckland-Shanghai service from February 9 until March 29.

The airline says the move is down to crew logistics and also a drop in bookings as a result of the coronavirus.

"Our teams are currently putting in place alternative travel options for customers impacted by the suspension and they will be contacted directly over the coming week," chief operational integrity and standards officer, captain David Morgan said.

Earlier, Qantas said it was suspending its services to mainland China from next Sunday.

The Australian-based airline said it would stop its two services from Sydney to Beijing and Sydney to Shanghai from February 9 until March 29.

This comes after entry restrictions imposed by countries including Singapore and the United States impacted the movement of crew who work across the Qantas International network.

"These entry restrictions pose significant logistical challenges for rostering crew to operate mainland China services, leading to the need to temporarily suspend these flights," the airline said in a statement.

"In selecting a date to suspend services Qantas is working to balance high passenger numbers in both directions – including Australian residents wanting to return home from China – with the various travel restrictions being applied."

New developments in the coronavirus outbreak have led the World Health Organisation to declare a global health emergency, the death toll surpassing 200 people.

Qantas said its services to Hong Kong were exempt from current travel restrictions.

The airline said the suspension could be brought forward if demand levels or other factors change.

"The date for flights to resume will also be regularly reviewed based on the circumstances," it said.

"Qantas is liaising closely with the Australian government on the impact of these changes to citizens currently in mainland China, and continues to take advice from the World Health Organisation and Australia's chief medical officer regarding the coronavirus in its decision-making.

"Qantas thanks customers for their understanding and its crew for their professionalism in light of these ongoing developments."
