Arrivals: International flights landing in a New Zealand port.
Departures: International flights leaving a New Zealand port.
Flights are only counted if at least one individual on the flight is recorded as an arrival.
Although most flights are scheduled commercial services, the numbers may also include charter services, private aircraft, cargo aircraft and other special flights.
Flights may visit more than one overseas port, and will be counted under each. Hence, the sum across overseas ports may differ from the total number of flights.
Since January 2020, governments have imposed international travel restrictions in multiple countries, due to the spread of COVID-19 around the world. In March 2020, the New Zealand government introduced further measures to protect New Zealanders from the COVID-19 virus, effectively limiting travel to New Zealand and travel within New Zealand.
