For 150 years, southern right whales (tohorā) were hunted to the brink of extinction. But the discovery of a “lost tribe” in the Southern Ocean sparked hope that their numbers are increasing. This documentary — made by veteran nature filmmaker Max Quinn for The Discovery Channel — follows a research expedition to learn about the pod. Breathtaking and intimate underwater footage, including a fabled white whale and new-born calf, reveals the behavior of these gentle giants. The award-winning film also captures soaring royal albatross, vomiting sea lions, and a flightless duck.

This full-length documentary looks at the grim reality of our fast-disappearing national symbol, and the efforts of people passionate about saving it. Remarkable facts about the evolutionary oddity are framed by the point that “the nation which laments that the moa was wiped out is committing the same crime against the kiwi”. The film raises the unsettling question: do we want the stoat or kiwi as our national icon? It also makes a compelling call to action to save a unique taonga, which could be extinct from the mainland in 20 years.

This documentary tells the tenuous survivor story of the kākāpō: the nocturnal flightless green parrot with "big sideburns and Victorian gentlemen's face" (as comedian Stephen Fry put it). A sole breeding population for the evolutionary oddity (the world's largest parrot; it can live up to 120 years) is marooned on remote Codfish Island. The award-winning film had rare access to the recovery programme and its dramatic challenges. This excerpt sees a rugged journey to the island to search for a kākāpō named 'Bill', and witnesses the "bizarre ballad" of its mating boom.

The Listener called the kids music of Fatcat & Fishface “like Tom Waits’ toy cupboard. The perfect antidote to Barney”. This ditty (from 2004’s Pretty Ugly album) came from a collaboration with the Department of Conservation and bypasses the cuddly usual suspects — kiwi etc — to celebrate the unlikely charms of the bat fly. The blind, flightless fly lives symbiotically on the native short-tailed bat: “So what if I like guano … I like it for a snack / There’s nothing like guano … from a bat!” The stop motion animation by Carlos Wedde is suitably Tim Burton-esque.

In November 1948 New Zealand got its own Lost World story, when a population of takahē — a large flightless rail, long thought extinct — was found in a remote part of Fiordland. The rediscovery of ‘notornis’ (a cousin of the pūkeko), by Southland doctor Geoffrey Orbell, generated international interest. This episode of the NFU’s Weekly Review newsreel series treks from Lake Te Anau high into the Murchison Mountains, where the team (including naturalist Robert Falla) find sea shell fossils, evidence of moa-hunter campsites, and the dodo-like takahē itself.

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 six-part series about Aotearoa's flora and fauna marked the first set of documentaries to be made by the BCNZ's freshly born Natural History Unit. The 15 minute episodes showcase White Island, bird life in Ōkārito, the flightless takahē, Waipoua Forest in Northland, wetlands near Dunedin and winter wildlife in Central Otago. Many of the filmmakers went on to make a mark — including directors Neil Harraway and Robin Scholes, and cameraman Robert Brown (The Living Planet). Hidden Places - Ōkārito was named Best Documentary at the 1979 Feltex Television Awards.

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.    

The giant, flightless moa, could stretch up to three metres tall and weighed up to 275kg. This documentary tells the story of the "mighty moa". It covers the bird's 19th Century rediscovery by English naturalist Richard Owen who surmised that the moa existed from bone evidence (leading to ‘moa mania' bone-trade); through ignition of hope that moa may still be alive when takahe (thought as dead as the dodo) were discovered in Fiordland in 1948; to digging up bird skeletons and remains of moa hunter culture in South Island swamps.

Why is New Zealand's landscape and flora and fauna so unique? In four-part series Moa's Ark, renowned English naturalist David Bellamy, with his impassioned enthusiasm and trademark beard (of "old man's beard must go" fame) goes on a journey to discover the answer. Directed and produced by Peter Hayden, this 1990 TV series was produced by Television New Zealand's award-winning Natural History Unit (now independent production company NHNZ).
