Built in 1949 it was originally used by the NZ Air Force when undertaking training in the area. The open fire was removed at some point, & the hut then removed in 2009. It was replaced by a newer hut on the same site. Edit Hut

On 16 June 1956, after being worked on by 21 men, the hut was finished and officially opened in the middle of “the best snowstorm experienced in the district for many years”. At 910m above sea level, the roughly 30m2 hut was intended to be used as a base for skiing, as well as for Woodbourne’s SAR team to train.
