Mountain Air was a scenic flight operation founded in 1988 and was based at the Chateau Airfield on the edge of the Tongariro National Park Dual World Heritage area.

Mountain Air was founded in 1988 by Keith and Robyn McKenzie and used a Cessna 172 and 206 to conduct scenic flights over the Tongariro National Park.

The company established an airstrip on a high country sheep station airfield at the base of the active volcano, Mount Ruapehu.

Two Britten Norman Islanders and two Piper Aztec aircraft were added to the fleet and services extended to provide New Zealand wide charter.

Schedule services were developed to provide several flights a day between Auckland International Airport, Whangarei and Great Barrier Island in the Hauraki Gulf in 1998.
