TVNZ’s Natural History Film Unit was founded in Dunedin around 1977. The first Wild South documentaries began filming a year later. The slot's initial focus was on New Zealand’s perilously endangered birds, eg the Chatham Island black robin (then the world’s rarest bird). The results won local and international notice, and a loyal audience. Wildtrack was a sister series showcasing natural history for young viewers. Wild South ended in 1997 when the Natural History Unit was purchased by Fox Studios; it later became internationally successful production company NHNZ.

This Wild South edition joins two legendary New Zealand wildlife documentarians — photographer Geoff Moon and sound recordist John Kendrick — on a 1988 trip to Kāpiti Island. Rangers are learning about, and looking after, the sanctuary’s manu (birds), who are “biological refugees” from the mainland, escaping introduced predators. Dogs monitoring kiwi, a kākā census, and tīeke (saddleback) nest boxes are featured. The two old mates narrate the visit, which includes Moon building a bush hide, and footage of a pioneering 1964 tīeke relocation from Hen Island.

Packed with creatures and landscapes that quite simply boggle the mind, the Nature Collection showcases New Zealand's impressive menagerie of nature and wildlife films. Many of the titles were made by powerhouse company NHNZ, which began around 1977 as the Natural History Unit, a small, southern outpost of state television. In this backgrounder, Peter Hayden — who had a hand in more than a few of these classic films — guides viewers through just what the Nature Collection has to offer.

When the takahē was rediscovered in the Murchison mountains in 1948, it made world headlines as a back from extinction story. This documentary checks in on the big flightless birds three decades later, with their future under threat (by deer, stoats and breeding failure). Doctor Geoffrey Orbell recalls the 1948 expedition. Project Takahē was the first Wild South documentary made by TVNZ’s Natural History Unit (later NHNZ). The images of takahē – blue, green and red, plodding in the snowy tussock – marked the first time most New Zealanders had seen the bird in the wild.    

In the mid 1970s the Chatham Island black robin was the world's rarest bird. With only two females left, the conservation ante was extreme. Enter saviour Don Merton and his Wildlife Service team. Their pioneering efforts ranged from abseiling the birds (including the 'Eve' of her species, 'Old Blue') down cliff faces, to left-field libido spurs. This 1988 Listener Film and TV award-winner united two earlier Wild South documentaries, and updated the robin’s rescue story to 1987. It originally screened on Christmas Day 1987, before being modified for this 1989 edition.

Flightless and nocturnal, the kākāpō is the world's heaviest parrot. By the 1970s the mysterious, moss-coloured bird was facing extinction, "evicted" to Fiordland mountains and Stewart Island by stoats and cats. Thanks to innovative night vision equipment, this film captured for the first time the bird's idiosyncratic courtship rituals, and the first chick found in a century. Marking the directing debut of NHNZ veteran Rod Morris, it screened in the Feltex Award-winning second season of Wild South, and won acclaim at the 1984 International Wildlife Film Festival.

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 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.  

The remote Antipodes Islands lie 860 kilometres southeast of Stewart Island. This 1980 documentary follows a Wildlife Service team surveying the islands’ inhabitants who are making all the strange noises – fur seals, albatrosses, petrels, parakeets and snipe, elephant seals and prolific penguins. It also investigates threats to their survival: mice and overfishing in the southern ocean. Winner of a Silver Medal at New York's International Film and Television Festival, this early Wild South episode helped establish the reputation of TVNZ’s Natural History Unit (later NHNZ).

This 1993 documentary surveys the world’s southernmost volcano, Mount Erebus. Cameras travel to never before filmed depths, 400 metres below the sea ice. They also go 3500 metres above sea level into the erupting crater. The film charts what is able to survive in the otherworldly environment, from seals to moss. Solid Water was the third part of an acclaimed Wild South trilogy on Antarctica, which helped establish a relationship between Discovery Channel and TVNZ’s Natural History Unit (later NHNZ). It was awarded for Best Camera at the 1994 New Zealand TV Awards.
