In the 1950s, driven by a desire to power around the shallows of the Mackenzie Country's braided rivers, inventor and "South Island sheep man" Bill Hamilton developed an improved method of jet boat propulsion. This NFU film explains the concept and Hamilton demonstrates the 'turbo craft': cruising Lake Manapouri, waterskiing Lyttelton Harbour, and heading up the Whanganui. Then it's spin outs and shooting rapids (and deer) with Commander Philip Porter from the icebreaker USS Glacier...who clearly loves the smell of the Waimakariri in the morning.

In this award-winning episode of the Rivers series, photographer Craig Potton visits Canterbury’s Rangitata River. The great braided river is home to the rare wrybill, and the landscape has provided inspiration for Samuel Butler (utopian satire Erewhon) and Peter Jackson (Mount Sunday is Edoras in Lord of the Rings). It’s been shaped by glaciers, the nor’wester, irrigation and farming. In this excerpt Potton and climbing mates try to reach the fabled Garden of Eden ice plateau and the river’s “pure heart”; a mission Potton and friend Robbie Burton failed to complete 30 years before.

This film tells the story of the world’s rarest wading bird, the black stilt (kakī). With its precise beak and long pink legs the stilt is superbly adapted to the stony braided riverbeads of the McKenzie Country, but it is tragically unable to deal with new threats (rats, ferrets, habitat loss). An early doco for TVNZ’s Natural History Unit, the magnificently filmed drama of the stilt’s struggle for survival makes it “stand out as a classic of its genre” (Russell Campbell). It won the Gold Award at New York’s International Film & TV Festival (1984).

This 1968 tourism promo follows two Aussie sheilas, Helen and Beverly, on a champagne-fuelled trip across the ditch. The tour kicks off with an obligatory sheep's 'baa', but offers some surprises alongside the scenic wonderland way, such as a detour to a Kaingaroa Forest mill and an Otago gold rush history lesson. Surprisingly trippy, Blow Up-inspired opening credits, some bold cutting and a jazzy score enliven the jaunt; a highlight is the lasses and hip local lads Monkee-ing around a Māori village and geothermal power station ... it's not PC, but it's definitely pop-tastic!

This documentary, made by TVNZ’s Natural History Unit (now NHNZ), charts the progress of the nor'west wind from its formation in the Tasman Sea across the Southern Alps to the Canterbury Plains and the east coast of the South Island. Along the way it dumps metres of precipitation on West Coast rain forest and snow on the Alps, then transforms to a dry, hot wind racing across the Plains. The film shows the wind's impact on the ecosystem and farming and muses on the mysterious effect it can have on humans. It screened as part of the beloved Wild South series.
