Passenger movements at New Zealand international airports

In arrival series, the closest overseas port is the last port that the passenger's flight visited before it arrived in New Zealand. This may not be the person's port of origin.
In departure series, the closest overseas port is the first port that the passenger's flight visited after it departed New Zealand. This may not be the person's destination.

From early 2022, some governments, including New Zealand, relaxed these restrictions, allowing more people to cross their borders. From 1 August 2022, New Zealand’s border opened to all visitors and international students.
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.
