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.

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.

Wildtrack was a highly successful nature series for children, combining a Dunedin studio set with reporting from the field. Produced by TVNZ’s Natural History Unit, it ran from 1981 until the early 1990s. Producer Michael Stedman sought to produce a series where “children can be excited and entertained with genuine information, while not neglecting adults”. Wildtrack won the Feltex Television Award for the best children's programme, three years running (1982 - 1984).  

Wildtrack was a highly successful nature series for children, running from 1981 through several series to the early 90s. In this episode the presenters check out “dung fungi” in cow pats and walking-on-water-insects (pond skaters) in the studio, and head outside to check out kea alpine parrots who are “too friendly for their own good” (threatened by smuggling and over eager tourists); the West Coast’s black sand beaches; Fiordland’s underwater world; and selective plant breeding that involves washing a bee.

This award-winning film looks at the strange and ethereal world of New Zealand's limestone areas. The rocks and caves reveal ancient whale fossils, moa hunter art — and evolutionary one-offs (like giant carnivorous snails) that live in a limestone world. The film goes into the darkness to find glow-worms, cave wētā, albino crayfish and skeletons of moa who met their death falling down tomos (shafts). In underground cathedrals, exquisite formations formed by the alchemy of water and limestone are captured. There is also footage of Waitomo Caves and Te Waikoropupu Springs.

The devastating effects of introduced wasps in New Zealand, particularly on kaka (the forest parrot, here beautifully filmed) remain a serious issue. The horde of yellow and black marauders has left scientists struggling to protect animal and human victims. This film looks at the effect on the ecosystem of wasps, who compete with natives for honeydew and prey upon insects. Bandits of the Beech Forest won the Environment Prize for Best Film Illustrating Protection, Preservation or Conservation of Bird Life at the Festival du Film de l'Oiseau.

In this episode of the Journeys series, Peter Hayden travels west to east across two national parks and some of New Zealand's most sublime landscapes: from giant, ancient kahikatea forest to hotpools and creaking glaciers. Reflections by ecologist Geoff Park (author of Ngā Uruora) on the coast-to-mountains forest, and the exploits of early surveyor Charlie 'Explorer' Douglas are woven through Hayden's journey, ending with Hayden's personal highlight of the series: climbing Hochstetter Dome with the legendary mountaineer (and Edmund Hillary mentor) Harry Ayres.  

From Māori myth to climbing and photography, to gliding and paraponting around its peak, Aoraki-Mt Cook is vividly captured in all its moods in this award-winning NHNZ portrait. Filmed for the centenary of the first ascent of a mountain that has claimed over 100 lives, it follows mountaineers as they climb toward the summit, re-enacting Tom Fyfe's pioneering pre-crampon route. Climbers, including Edmund Hillary, reminisce about encounters with NZ's highest and most iconic peak; and Bruce Grant takes the quick way down: a vertiginous ski descent.
