From a pre-Mythbusters but post-blackboard and pointer era, Christchurch-produced Science Express took a current affairs approach to reporting contemporary NZ scientific research. Presented by broadcaster Ken Ellis this 1984 ‘best of’ dives beneath fiords to explore mysterious black coral forests; and looks at teeth transplants, efforts to stimulate deer fawning, and the STD chlamydia. Finally the show visits Wellington and Christchurch Town Halls to profile concert hall acoustics pioneer Harold Marshall, and his mission to attain perfect sound for listeners.

This 1970 documentary surveys New Zealand’s dairy industry — “probably the most advanced in the world” — from pasture to export. Dairying then produced a quarter of NZ’s income, but with Britain due to join the EEC, NZ was forced to seek new markets. This film proclaims the industry’s readiness, thanks to an artificial breeding centre (with ‘calf-eteria’), room-sized computers, and cheeses designed for the Asian market. The country's 25,000 dairy farms were each owner-operated, and averaged 90 cows. The Dairy Industry won top prize at an agricultural film competition in Berlin. 

Rodeo thrills and spills — Kiwi style — are on display in this documentary following two cowboys travelling the circuit in a 1950s Chrysler. They compete in events in Fairlie, Rerewhakaaitu and Warkworth, and encounter American and Australian stars along the way. Broncos, calves and bulls are ridden, wrestled or roped; but pride of place goes to spectacular shots of them using rodeo skills to capture deer by helicopter. A parade, the 'Cowboy's Prayer' and fearless rodeo clowns also feature. Legendary commercials maker Geoff Dixon (founder of company Silverscreen) directs.

This 1999 documentary goes behind the scenes with veteran Antarctic filmmaker Mike Single, as he films icebergs in the Southern Ocean. To Single they’re "ice creatures" and his mission is to get to their dynamic "essence". He and his crew face time pressure, storms, cabin fever, and challenges shooting underwater. Some of Single's shots of epic ice sculptures, calving glaciers, crabeater seals, gentoo penguins, humpback whales and trademark time-lapse cloudscapes also appeared in his documentaries Crystal Ocean (a 2000 Emmy Award-winner), and Katabatic.
