Travellers are being being advised to allow half an hour extra for their journey through Auckland International Airport and customs.
Passengers numbers are expected to be in excess of 30,000 people per day as Auckland Airport gears up for some of its busiest days of the year.
Airport general manager Judy Nicholl said December and January are the busiest time of the year.
The busiest days of the year range from December 19 to January 31, with some of them falling consecutively.
"To help support the growth in passenger numbers, Auckland Airport has recently increased its international baggage belt capacity by 40 per cent, added 17,500 square metres to the airfield for aircraft parking, and next week we complete the construction of a new gate bus lounge on Pier B of the international terminal," she said.
