On a nice Saturday afternoon I was able to photograph a few of the pretty varied collection of aircraft that they have outside (not that these were all of them):
The Fairey Swordfish mock-up is part of a children's play area. This is the ex MOTAT example that was built by Fleet Air Arm veterans many years ago.
The remains of of DH 104 Devon ZK-UCO (ex NZ1812) sit rather forlornly beside one of the hangars.
Sud SA316C Alouette III ZK-HYA2 is now more complete and is outside.
Vans RV 3 ZK-RVE is still hanging around in one of the museum hangars.
And Air Chathams DC 3 ZK-AWP was providing flights from the Classic Flyers apron.
