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 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 long-running nature programming slot on TV One, naturalist David Bellamy visits New Zealand’s “dinosaur forest” — Whirinaki. Bellamy brings his famed nature-boy enthusiasm to “a living cathedral that dates back 200 million years”. He explores the North Island forest’s “big five”: 60m+ rimu, mataī, kahikatea, miro and tōtara trees; and the ecosystem that they reign over, from kākā parrots to giant tree ferns. The intro is by Gael Ludlow and features the fondly-remembered Jean Michel Jarre synthpop track that was Our World’s signature.

This 76-minute documentary looks at efforts to restore the mauri (life spirit) of Northland's Lake Omapere, a large fresh water lake — and taonga to the Ngāpuhi people — made toxic by pollution. Simon Marler's film offers a timely challenge to New Zealand's 100% Pure branding, and an argument for kaitiakitanga (guardianship) that respects ecological and spiritual well-being. There is spectacular footage of the lake's endangered long-finned eel. Barry Barclay in Onfilm called the film "powerful, sobering". It screened at the 2008 National Geographic All Roads Film Festival.

This film looks at biodynamic agriculture, a Rudolph Steiner-inspired system of organic farming. The film focuses on Peter Proctor, a worm-obsessed Kiwi gardener, and his work promoting biodynamics worldwide — particularly in India, where he argues that modern industrial agriculture (eg artificial chemicals, GM seeds) has made soil and plants toxic and farming unsustainable. Proctor's simple recipe to save the planet? One man and a bucket of cow dung. Narrated by American actor Peter Coyote (E.T.), One Man screened worldwide at environmental film festivals. 

This NHNZ documentary looks at the fierce debate between animal lovers and ecologists over the wild horses of the Kaimanawa Ranges (with striking footage of them running free). At issue: a delicate tussock land ecosystem with rare native plants dating back thousands of years, increasingly at risk from horses recognised for their uniqueness — but whose numbers have grown tenfold in 15 years. Reducing the herd size is the favoured option. But only younger horses can be sold and, with older ones going to an abattoir, the plan is opposed by the horse lobby.

Made for the UN's first 'Earth Summit' in Stockholm in 1971, the film explores what the future holds for NZ’s environment. Director Hugh Macdonald (This is New Zealand) presents an impressionistic ecosystem: mixing shots of native natural wonder, urbanisation, and pollution with abstract montages and predictions from futurologists — such as Cousteau’s “underwater man”. Before climate change heated up 21st Century Doomsday debates, this film (made for the Ministry of Works!) places stock in individual responsibility. The score aptly enlists the French nursery rhyme ‘Are You Sleeping?’.

This documentary advocates for the protection of one of the last pristine ecosystems on earth: The Ross Sea. Veteran cameraman Peter Young vividly captures the frozen wilderness — freewheeling penguins, fish and sealions under the aquamarine ice — and interviews scientists concerned at threats posed by commercial fishing (including from New Zealand-owned boats). The film confronts unsuspecting New York diners with the origins of their fish, exposing upmarket ‘Chilean sea bass’ as Antarctic toothfish. Last Ocean won Best Film at the 2013 Reel Earth Film Festival.
