Prelude to Aspiring was the first National Film Unit title directed by legendary photographer Brian Brake, soon after he joined the Unit in 1948. It follows a group of climbers up the Matukituki Valley, west of Wanaka, towards Mt Aspiring for the opening of a new hut and a trudge through snow to resurrect a flattened shelter high up Mt French. The autumn alpine scenery is breathtaking even in black and white, and the film perfectly performs its role as one of a series of promotional ‘documentaries' made by the NFU.

This 1972 NFU documentary follows three climbers (Hugh Canard, Neil Hamilton and pioneering guide Bruce Jenkinson) on an ascent of Mt Aspiring. Directed and photographed by Grant Foster (Land of Birds), the beautifully-shot short film heads up country in the Land Rover. Rivers are crossed in the sun, then the climbers rope up and get the pick axes out. It’s tea, food and harmonica in the hut, then a pre-dawn start (“hell it’s cold!”) before cutting steps and leaping crevasses up the “matterhorn of the south”. The film screened on PBS in the United States.
