The Marlborough Aero Club at Omaka is currently hosting the 5th edition of the NZ Aerobatic Club's South Island Akro Fest and this has attracted a number of interesting participants including the Bushby Midget Mustang ZK-DDC from Otago. This has been around since 1975 but still looks very smart.
From Te Anau the 2 seater Pitts S2A ZK-PIT
And from Christchurch the recently returned to NZ Pitts S1S ZK-PUG
Elsewhere on the field was Precision Helicopters AS350B2 ZK-ITJ2 which was imported from Canada in late 2017
And yet to officially enter the CAA register the Air Tractor 402B ZK-MOT3 being readied for Motunau Ag Air. This is s/n 971 and was imported from Australia where it was registered VH-FAQ.
