In May 1983 Eugene Mortensen, a long time James Aviation topdressing pilot in Northland, and his wife Jill Mortensen applied to the Air Services Licensing Authority to conduct a non-scheduled air service between Kaikohe and Auckland and air charter, air taxi services and scenic flight or joy ride services from Kaikohe and Kerikeri to any licensed aerodrome in New Zealand with a fleet of one Aero Commander 500, one Cessna 172, and one Piper Pa28 Cherokee. The Cessna 172 and Piper Cherokee are indicative of Mortensen’s connection to the Bay of Islands Aero Club.

In addition to the air service the Aero Commander was also regularly used to fly mussel spat from Kaitaia to Blenheim. A further development to increase the utilisation of the aircraft was the Bay of Islands Aero Club seeking to include the Aero Commander its air charter licence in November 1983.

On the 28th of February 1984 Eugene Mortensen flew to Dargaville for talks with local authorities, travel agents and the local Aero Club about the possibility of Dargaville being included in the service. Local councillors and travel agents were taken for a flight over the town. Dargaville was included in the service from the 19th of March 1984. The timetable remained relatively the same with the flight leaving Dargaville for Auckland at 8.45am and returning at 5pm. The company also promised a Tuesday service if there was enough demand.
