New Zealand's relationship with Antarctica and the explorers and scientists who went there is the focus of this episode in The Years Back series, with Bernard Kearns as guide. Early last century NZ was the starting point for most polar expeditions, including Robert Falcon Scott's fatal attempt to reach the Pole. Footage of Scott on the ice is featured, and as well as clips of Sir Ernest Shackleton’s epic survival tale. Of course the Sir Edmund Hillary-led 50s Kiwi expedition is shown: Hillary made a defiant dash for the Pole on tractors, arriving 4 January 1958.

Though it plays hell with cameras, Antarctica has long fascinated filmmakers. This hour-long National Film Unit documentary was assembled from a five-part TV series of the same name. There are looks at scientific research, early explorers, and Antarctica's affect on global climate. Made four decades ago, the programme warns of a possible "new and potentially dangerous warming period", and calls the greenhouse effect a "controversial scientific theory". The large cast includes penguins, a seal birth (clip two) and a heavyweight team of Kiwi scientists.
