That is the nose of Cessna A150L ZK-DNO (c/n 1500448) of Air Napier Ltd on the left - still wearing Wakelin Aviation script; with the Piper PA31 Navajo ZK-NPR (c/n 777) of Air Napier and the Cessna 152 ZK-NPD2 (c/n 152880188) also with Air Napier.
In the background are the two Sunair Piper PA23-250 Aztecs. ZK-DIR is a "D" model (c/n 27-4242) and ZK-DGS is an "E" model (c/n 27-7304959).
Above is a very long shot of the Beechcraft B200C Super King Air ZK-PLK (c/n BL-64) of Skyline Aviation feeling for the earth.
