Auckland Airport is still struggling to fill major gaps in its workforce.

It has 1600 job openings, ranging from roles in check-in to bag collection, through to food and beverage to security.

Air New Zealand expects to carry 2.8 million passengers between December 15 and January 31, up from 1.1 million last year.

Chief Executive Carrie Hurihanganui says they're doing all they can to make things work, but warns the staff shortage will lead to longer queues and wait times.
