Cessna 172 c/n 29604 was initially allocated the US registration of N6404B but this was not taken up and it was test flown prior to its shipping to New Zealand using the Cessna test registration of N11B in the latter part of 1956.
It was crated off to New Plymouth for Rural Aviation and was registered in New Zealand as ZK-BSU on 14-12-1956 and was issued with a NZ CofA on 22-02-1957.
It was taken up by the Hawera Aero Club from 05-04-1957 but was involved in a forced landing near Takaka on 29-07-1961 and ended up back with Rural Aviation at New Plymouth and following repairs was registered to them on 01-02-1962.
Four days later it was listed with the Taupo Aero Club until it had a pilotless take off from Taupo on 26-07-1963.
A year later on 08-05-1965 in a forced landing due to inclement weather near Turangi it struck trees and ended in the scrub.
Its registration was cancelled and was sold 'as is' to Arthur N Reville on 23-08-1965 who rebuilt it and re-registered it as ZK-CWK on 30-01-1968 with it going online with the Auckland Flying School until acquired by General Finance Acceptance Co Ltd of Wellington from 31-03-1969.
It was leased to the South Otago Aero Club at Balclutha.
