Auckland's only available airport is, at this point, Whenuapai. This is a mid-size airport which in real life served as a temporary international terminal.
The current Auckland international airport, Mangere, was planned and opened in the mid-60s. At that point, Whenuapai was closed and Mangere became the only international terminal of the city, becoming Whenuapai a military base.
Will this happen in the game as well?
