Warbirds over Wanaka is a biennial air show in Wanaka, held on the Easter weekend of even-numbered years. It is held at Wanaka Airport, 10 km outside Wanaka village. Initially conceived by New Zealand live deer recovery pioneer, Sir Tim Wallis, as a display day for him to play with his collection of World War II aircraft, the show has grown into a major institution. Roads are closed and traffic is detoured around the area during the weekend.
