The formal parade took place on the Whanganui War Memorial Centre forecourt on Saturday afternoon, Mr Quirk said. It flew the New Zealand Cadet Forces Banner.
It was reviewed by two former cadets, Group Captain Nick Olney, the RNZAF Ohakea Base Commander, and Warrant Officer Ritchie Pleasants, a Base Warrant Officer also at Ohakea.
Group Captain Olney congratulated No.9 Squadron and the Air Training Corps on their anniversary, and talked about his own time as a cadet.
After that about 200 people watched a film on the squadron's history at the Davis Lecture Theatre.
That night there was a dinner that drew in ex-cadets from late 1950s through to current cadets. Stories, memories and photos were shared.
The weekend ended on Sunday with former cadets joining squadron members and members of the public attending the Battle of Britain Commemoration Service at St Peter's Church in Gonville.
In the early 1940s the squadron's main focus was to train young men to join the Royal New Zealand Air Force, and a number of them were deployed overseas.
After the war the number of cadets decreased, Mr Quirk said. During the 1950s and 60s the squadron became more youth focused.
In 1971 the Air Training Corps stopped being part of the RNZAF and joined the Sea Cadets and Cadet Corps (the army equivalent) to form the New Zealand Cadet Forces.
