Niue Airline was an airline in Niue, established in 1990. It serviced the Auckland-Niue route weekly, and later fortnightly, until its closure in 1992. The route was operated by a chartered Air Nauru 737 and carried mail. Flights were sometimes cancelled if passenger numbers or freight was not enough to fund the flight. The airline was majority New Zealand-owned (with some Niuean investment). In 1991, services were operated from Auckland to Niue, and returned via Tonga.
