Cessna 185A Skywagon ZK-DPY (c/n 1850270) was allocated the US registration of N4070Y on 07-12-1961 but because it was built for export it probably never carried these US marks. Foreign bound Cessna's were often painted in their future markings and flown under the Cessna test/trade allocation of N11B. They were then flown down to Houston for shipping. 1850270 was shipped out to Rex Aviation Pty Ltd at Bankstown, Australia for onward delivery to E Pendercost of Noumea, New Caledonia, with whom it became F-OBYE on 14-06-1962. I believe it was shipped to NZ in late 1973 to be registered here as ZK-DPY, first flying as such on 08-01-1974 with Rex Aviation (NZ) Ltd at Ardmore. It was listed to Southwest Helicopters Ltd of Taupo by the 18th, but did not stay long, as by 09-07-1974 it was re-listed to Woody Rouse, R G Selbie and R A Soper of Lumsden and I seem to recall that it was based on the Five Rivers airstrip.
Airflite South Ltd of Taieri acquired it as from 10-02-1982.
