Due to a change in our plans I had to return to Dunedin Airport on 23 March to pick up another rental car to drive to Christchurch. It is not easy to get photos of aircraft at Mainland Air but I tried:
Beech V 35B Bonanza ZK-EDJ is registered to a Queenstown owner. It is one of only two V tailed Bonanzas on the register (the other being ZK-DDG).
And the Tecnam P 2006T ZK-MTW while being registered to a Putararu owner, has a Mainland Air logo on the tail (apologies for the heat haze which is surprising as there had been quite thick fog all morning).
