Should have done some basic research before making my request! Found two more aircraft operated by this club. ZK-AXF, Auster J/1B (2674) converted to J/1Y 1968, 24 Jan 1956 - 27 Feb 1973. ZK-BSC, PA-22-150 Tri-Pacer (22-5410), 6 May 1963 - 30 Aug 1970, w/o near Eltham.
As for airline/aircraft manufacturer/military service flying clubs, plenty here (and overseas I'm sure). The NAC club was based in Christchurch but there was a similar club in Palmerston North. The NAC club became in time the Air New Zealand Sports and Social Club.
