Mit has asked about the Auster that was in the background to one of the photos in the Pulsar #2 blog below.Almost certainly Auster J-1 ZK-AUO (c/n 1955). This was built as G-AHAX and registered to Taylorcraft Aeroplanes - England Ltd on 02-04-1946 and had two private English owners before being imported into NZ to become ZK-AUO on 11-07-1950 with Mort Vanderpump of Napier City Air Services. After a period with the Napier Aero Club from June 1952, and a private owner at Raetihi from July 1954 it moved south to Southern Scenic Air Services Ltd at Queenstown from 30-07-1955. From 1957 onwards it has had a whole bunch of private owners.
The Auster J-1 ZK-APO (c/n 2212) was also operating around the Queenstown, Taieri area over the same time period. also in a red and white scheme and they were easily mistaken for each other, until AUO adopted the yellow with thin brown trim scheme.
