International Travel and Migration Population
Arrival and departure statistics include all people crossing New Zealand's borders, with exceptions for crew, military personnel, and Antarctic personnel as outlined in the Immigration Act 2009.
People who remain in the transit lounge and do not pass through Customs do not cross the border, and so are not included in arrival and departure statistics.
Cruise passengers arriving in and departing New Zealand on the same cruise ship are exempt from filling in arrival cards and so are not included in arrival and departure statistics. Cruise passengers who end their journey in New Zealand do fill out arrival cards and are counted in the statistics. Almost all of these people travel by air in the opposite direction.
