I was scratching around on Google yesterday (as you do on a grotty day) on a completely different topic and this photograph popped up.
It shows what appears to be the Avro 616 Avian IVM ZK-ADQ (c/n R3/CN/435) refuelling on what looks suspiciously like the main street through Saltwater Creek at Timaru.
ZK-ADQ was constructed as G-AATV for Shell Mex Company of Egypt.
It gained its UK C of A on 30-01-1930 and was cancelled in March of 1933 to take up the Egyptian marks SU-AAG.
It took up its old G-AATV registration again from 12-09-1934 with Flying Officer Geoffrey Twyford Jarman of 47 Squadron RAF, Khartoum, Sudan.
Its UK registration was cancelled on 02-03-1935 and it then became ZK-ADQ on 05-05-1935 with K R Johnstone of Timaru.
Other owners that I know about were P W Wilton; Charlie Liddell of Wellington from 10-05-1942 and then Southern Cross Aviation Services Ltd from 19-05-1948.
It crashed at Willowbridge (near Waimate) on 13-06-1948 with ownership going to J H Craig on 05-07-1948 and was cancelled on 29-10-1948.
At some point it was fitted with a DH Gipsy Major engine..
