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.

This Feltex Award-winning documentary follows the 1977 Indo-New Zealand Ganges expedition, where Sir Edmund Hillary and crew (including son Peter) attempt to jet-boat upriver from the mouth of the Ganges to its Himalayan heart. There, they aim to make a first ascent of Akash Parbat. The adventure pilgrimage was a proof of concept for the Kiwi-invented boat, and a return to action for Ed after mourning the death of his wife and daughter in a 1975 plane crash. The mission faces epic white water, altitude sickness and tigers, as they’re cheered on by throngs on the river’s banks.

This award-winning series took Wellington chefs Al Brown and Steve Logan out of their fine-dining restaurant, to experience the local in 'locally sourced' kai. In this second episode, Al and Steve head to Tangahoe up the Whanganui River, looking for wild pig with a couple of good keen men — Baldy and Moon. Logan is with the dogs on the boar hunt; while Al's on veggies at the markets, before hitching a flying fox to sample some freshly baked organic kumara bread en route up river. The bush tucker result? Cider braised pork belly with kumara and corn mash.

It was a Kiwi that invented the jet-boat, so it is probably unsurprising that at the time of this film’s production New Zealand teams had won Mexico's Rio Balsas Marathon three times. Directed by Derek Wright, the award-winning NFU doco showcases what was then the longest jet-boat race yet staged: a five-day 1000km race across NZ, with the locals putting their trophy on the line. The race hits the rapids and — despite the odd tree stump — speeds past scenery on six rivers (from the Whanganui to the Waimakariri), Lake Brunner, and through the surf to Sumner Beach.

Made by the NFU for the NZ Water Safety Council this film enlists shock to provoke punters to consider water safety. On a summer’s day a fisherman, surfer and boatie all reckon it's “a great day for it”. But thoughtlessness results in tragedy. Directed by Hugh Macdonald (This is New Zealand), the disjunct between the jaunty song on the soundtrack and sunken bodies onscreen anticipates the graphic horror of the late 90s/early 00s road safety ads (sharing kinship with 1971 bush safety PSA Such a Stupid Way to Die). Grant Tilly cameos as a radio DJ.

This edition of the National Film Unit’s long-running monthly magazine series features a diverse line-up. The first report covers the opening ceremony of the meeting house at Waiwhetu Marae, Lower Hutt, where Prime Minister Walter Nash and Sir Eruera Tirikatene receive the pōwhiri and haka. Then it’s a canter to Auckland’s 1960 Pony Club Championships; before flowing down south for the diversion of the Waitaki River in the Otago town of Otematata, as part of the Benmore hydroelectric scheme: a massive earth dam destined to be the “powerhouse of the South Island”.

This series aimed to introduce and encourage young Kiwis into the outdoors. Fronted by climber Graeme Dingle, and based at Turangi's Sir Edmund Hillary Outdoor Pursuits Centre (co-founded by Dingle in 1973), it was produced for the Department of Education. In this sixth episode Dingle surveys the history and confidence-building philosophy of the centre, showing rafting, rope courses, and a bush rescue. He also revisits influential moments in his adventuring career, from heading up the Ganges in a jetboat, to helping disabled climber Bruce Burgess up Ruapehu.

NFU-produced TV series These New Zealanders explored the character and people of six NZ towns, 60s-style. Fronted by Selwyn Toogood, it was one of the legendary presenter's first TV slots. In this episode Toogood dons the walk shorts and long socks and visits Taupō, extolling the lake district as a place of play (camping, fishing, swimming, jet-boating) and work (the development of Lochinver Station for farming). Toogood does a priceless vox pop survey of summertime visitors, including the requisite quizzing of an overseas couple about whether they like it here.

Introduced to New Zealand in 1851, red deer soon became controversial residents: sport for hunters, but despised by farmers and conservationists for the damage they caused. First targeted by government cullers in the 1930s, by the 60s they were shot by commercial operators for venison export. Directed by Bruce Morrison and Keith Hunter, this award-winning documentary catches up with the hunt in the 70s, when deer for farming – dramatically caught alive, from helicopters – was a multi-million dollar gold rush. Different versions of the film were made for overseas markets.

Made by the NZ Broadcasting Corporation in the mid 1960s, this half hour TV documentary sets out to summarise New Zealand. More than a promotional video, it takes a wider view, examining both the country’s points of pride and some of its troubles. In a brief appearance Barry Crump kills a pig, although the narration is quick to point out that the ‘good keen man’ image he epitomises is also a root of the country’s problem alcohol consumption. The result is patriotic, but certainly not uncritical. Writer Tony Isaac went on to make landmark bicultural dramas Pukemanu and The Governor.
