The best airport in Australasia. Again.

An independent international survey has found Christchurch Airport to be the best in Australasia, for the 7th quarter in a row.

Christchurch Airport CEO Jim Boult says the result is testament to the thousands of people who work at the airport every day.

"There are six thousand people working on the airport campus every day and every one of them cares about the experience visitors have while they are here," says Mr Boult.

"The survey interviews travellers who rate more than 30 different aspects, from the arrival experience, to food and beverage, to cleanliness of the facilities - and we are working hard to make every one of those the very best we can.

"The survey results suggest we are getting most things right, but also help us work out where we need to tweak things a little."
