Ardmore was constructed during World War II by USAAF forces stationed in Auckland, and was intended to be used as a base for B-17 Flying Fortress bombers. Due to developments in the Pacific War it was never used for this purpose; but was instead was used by the RNZAF, who operated Corsair fighters. RNZAF Auckland operations were consolidated at Whenuapai after the end of World War II. From the post-war years until the mid-1970s the grounds were home to a teacher training unit and the Auckland University School of Engineering.

From 1954 until 1962 the aerodrome was home to the New Zealand Grand Prix with the circuit being approximately 2 miles (3.2 km) in length and utilising the two sealed runways operational at the time. In 1954 and 1955, about 70,000 spectators attended the event. Local authorities made the decision to open up the facility to general aviation and so the Grand Prix was moved to Pukekohe upon completion of a purpose built facility there.British racing driver Ken Wharton was killed at the NZ Grand Prix at Ardmore on 12 January 1957, when he crashed his Ferrari Monza.
