Travel - Visitor arrivals by every country of residence and purpose Year ended December 1922–2023

Country of residence: the country where the person last lived or will next live for 12 months or more.
Travel purpose: the main purpose for the visit to New Zealand or trip overseas. Categories are holiday, visiting friends and relatives, business, conferences and conventions, education, and other.
Visitor arrivals: Visitor arrivals are overseas residents arriving in New Zealand for a stay of less than 12 months.

These statistics relate to the number of passenger movements to New Zealand, rather than to the number of people - that is, the multiple movements of individual people during a given reference period are each counted separately.
From March 2020 to July 2022, the New Zealand government implemented measures to protect New Zealanders from the COVID-19 virus, effectively limiting travel to and from New Zealand.

A person may change their intentions after their arrival, which may mean the recorded passenger type becomes incorrect. Stats NZ does not revise published statistics for such changes, but advises that the published figures remain a good indicator of trends in permanent and long-term migration.
Data is derived from a sample of records and hence may contain sample error. Caution should be used when using data with low cell values.
Note: the 2023 data for countries with small samples is subject to high level of misclassification error and should be disregarded.

'Transit' passengers do not complete border clearance - regardless of whether they travel by air or by sea - so are not included in these statistics. About three-quarters of cruise ship passengers visiting New Zealand are 'transit' passengers.

Imputation of 'country of residence' for visitor arrivals who have not stated a response on their arrival card, occurred from August 2016 to October 2018.
From November 2018, 'country of residence' was fully captured and no longer sampled, resulting in an increase in the 'not stated' category.
From December 2019 country of residence remains fully captured, but is imputed for visitor arrivals who have not stated a response on their arrival card
