This divides passengers in to one of three groups: overseas visitors; New Zealand-resident travellers; permanent and long-term migrants/migrants. (Collected for all passengers)
Overseas visitor arrivals - People who live overseas and are visiting New Zealand for a stay of less than 12 months
Overseas visitor departures – Overseas residents departing New Zealand after a stay of less than 12 months.
New Zealand resident arrivals – New Zealand residents arriving back after an absence of less than 12 months.
New Zealand resident departures - Before November 2018, New Zealand-resident traveller departures were New Zealand residents departing New Zealand for an absence of less than 12 months. From November 2018, New Zealand-resident traveller departures are New Zealand residents departing New Zealand irrespective of duration of absence.
Permanent and long term arrivals - People arriving for a stay of 12 months or more, including New Zealanders returning after an absence of 12 months or more.
Permanent and long-term departures – New Zealanders departing for 12 months or more, and migrants leaving after a stay of 12 months or more in New Zealand.

Migrant departure (outcomes-based measure) - A migrant departure is a New Zealand resident who departs New Zealand and cumulatively spends 12 out of the next 16 months out of New Zealand.
Net migration - Net migration is the difference between the number of migrant arrivals and departures. When there are more migrant arrivals than migrant departures there is a net gain in migration, and when there are more migrant departures than migrant arrivals there is a net loss in migration.en-NZ
