The RNZAF’s only Beaver was purchased in 1956 for the Commonwealth Trans-Antarctic Expedition.

The original Beaver NZ6001 was one of two RNZAF aircraft attached to the 1955-58 Commonwealth Trans-Antarctic Expedition, purchased largely with money from public donations. It could be fitted with skis or a wheel/ski combination and made its first flight at McMurdo Sound on 15 January 1957. It returned to New Zealand in 1958 but went south again for the 1959-60 summer season.
