By 1976 there were only seven Chatham Islands black robins left. It was the world's rarest bird. In a bid to save the species, the surviving birds were taken from one island to another more hospitable island in a desperate rescue mission. This was part of an incredible conservation success story led by Don Merton and his NZ Wildlife Service team. Seven Black Robins and Project Takahē captured viewers' imaginations as part of an acclaimed series of 'rare bird' films that screened on TV series Wild South. They helped forge the reputation of TVNZ’s Natural History Unit (later NHNZ).

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.

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.

“These three birds are over half the world population of their species.” Peter Hayden’s narration lays bare the stakes for the Chatham Island black robin, and the Wildlife Service team (led by Don Merton) trying to save them. Merton’s innovative methods include removing eggs from nests – to encourage the last two females to lay again – and placing them in riroriro (grey warbler) foster homes. The black robin documentaries helped forge the reputation of TVNZ's Natural History Unit. Paul Stanley Ward writes about the documentaries here, and the mission to save the black robin.

Predators (possums, rats, rabbits, deer) forced much of the cargo of 'Moa's Ark' to abandon ship and live on off-shore island lifeboats. Moa's Ark presenter David Bellamy visits them (and recently-established mainland 'islands'), and tells some of New Zealand's most dramatic conservation stories. In the fourth clip, he praises the pioneering leadership of Don Merton. The episode includes footage of kōkako and its haunting song, cheeky kaka parrots, tieke (saddleback), hoiho (yellow-eyed penguin), black robins, fierce-looking giant wētā, and the Castle Hill buttercup (the world's rarest).

Nearly mammal free, pre-human New Zealand was a land of birds, many of them found nowhere else. In Birdland, Jeremy Wells (Eating Media Lunch) explores all things avian in Aotearoa. In this opening episode he visits Hauraki Gulf island sanctuary Tiritiri Matangi and Christchurch’s Peacock Springs. Putting the wry into wrybill, Wells muses on manu matters from twitching to tākahe poop. Dominion Post’s Linda Burgess praised Mike Single's "marvellous camera work", and Wells’ celebration of ordinary people "who work to protect and enhance what we still have".

Host Marcus Lush called this 2009 series a "love letter" to the characters and stories of the south. In this first episode he sleeps over on Dog Island (where he learns a lighthouse doesn’t have curved beds). Then it’s down to Stewart Island to join "Robin’s teepee cult" and meet Mason Bay whānau, and back to the Aucklander's adopted hometown of Bluff to chat with artistic beachcombers. South continued JAM TV’s winning collaboration with Lush (Off the Rails, ICE). At the 2010 Qantas Awards, the series collected gongs for best presenter and for director Melanie Rakena.

This four-part series explores New Zealand social history through rugby, from the first rugby club in 1870 to the 1995 World Cup. In this episode commentators muse on the roots of rugby in a settler society, in "a man's country". Rugby's unique connection with Māori, from Tom Ellison and the Natives’ tour to a Te Aute College haka, is explored; as well as the national identity-defining 1905 Originals’ tour, and the relationship between footy and the battlefield. As the Finlay Macdonald-penned narration reflects: “Maybe it's just a game, but it's the game of our lives”.

This wee gem from the 60s Sunday night magazine show records a pivotal New Zealand conservation moment. Wildlife Service ranger Don Merton experiments with rescue techniques to save the endangered North Island saddleback (tieke), a wattlebird surviving on Hen Island. Aided by electronics expert John Kendrick (of National Radio bird call fame) he uses calls to lure the spry birds into mist nets before moving the precious cargo to cat-free Cuvier Island. The world-leading skills developed here were to be crucial in saving the black robin and kakapo from extinction.
