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.

This documentary follows a Southern Alps ski competition for local and off season northern skiers. Organised by Coast to Coast impresario Robin Judkins, the ‘grand slam’ series begins with a chopper ride to Black Peak for powder 8 and telemark skiing; and then it's above Lake Wanaka for slalom, ski jumping, and a grunty "air, style and speed" mogul. Après-ski competing there's a springtime descent down Mt Taranaki. It wouldn't be Kiwi skiing without kea, and the discipline of the inner tube. The crisp sax and synth 80s score is by Hello Sailor's Dave McArtney.

The Southern Alps contain some of the youngest mountains in the world. In this NHNZ documentary awesome four seasons footage and sound design evoke the the tenuous richness of life in the vast, geologically dynamic landscape. Garrulous kea (the world’s only mountain parrot), Himalayan thar, “snow thrush” (crickets) and Mount Cook buttercup (the world’s largest) exist in a world of thundering avalanches and creaking glaciers. The classically filmed doco won a Merit Award at the 1993 International Wildlife Film Festival, Missoula.

This documentary tells the epic story of helicopter deer culling in the Southern Alps. Introduced deer had become destructive environmental pests; in the 60s entrepreneurs shifted culling from ‘man alone’ to machine-driven hunting, as deer were shot then later captured alive from helicopters. Deer Wars — Top Gun in choppers, over the beech forest — revisits the heady ‘gold rush’ days, when heli-cowboys calculated often fatal pay-offs between risk and reward. It features interviews with survivors and fearsome footage of men hanging from helicopters and leaping onto deer.

After bad weather curtailed an ambitious film about Mount Aspiring in 1949, Brian Brake returned to the Southern Alps the following year to shoot Mount Cook — the first NFU film to feature Brake's mountain imagery in glorious blue and white colour. The wait was worth it: the longtime mountain-lover coaxes a succession of breathtaking images of the cloud-piercing mountain — plus a rollicking snow fight scene. The plot, what there is of it, centres on some skiers wandering closer to Aoraki/Mt Cook to get a better look, then demonstrating the joys of descent. 

Off the Edge was director Michael Firth's ode to the exhilaration of adventuring on the spine of New Zealand's Southern Alps. Something of a snowy Endless Summer, the film follows an American and a Canadian as they ski, hang glide, climb and delve beneath glaciers, in the Aoraki-Mt Cook area. Thrilling footage amidst spectacular scenery was shot over two seasons, where extreme weather and geography meant few chances for second takes. The film was nominated for an Oscar for Best Documentary in 1977. The Los Angeles Times called it "beautiful and awesome".

Jackie van Beek directed and starred in this 2014 short film, playing a tramper who finds her solitude interrupted in a Southern Alps hut. The short was filmed in Arthur’s Pass, where van Beek spent time climbing and exploring near her family crib, while growing up. Uphill won Best Film at an international showcase for organisation Women in Film and Television International; van Beek also won Best Actor at Kiwi festival Show Me Shorts. She would collaborate again with producer Aaron Watson on her feature directing debut, 2017 drama The Inland Road. 

"For the farmers of the high country the snowline is their boundary". So begins the narration to this National Film Unit documentary. Beautifully shot by Brian Brake, the challenges of farming the vast stations on the rugged aprons of the Southern Alps are captured. The centrepiece is the great autumn muster where shepherds and dogs work 16,000 sheep down from "the tops" over 100,000 acres of peaks and glaciers, before the snow and winter blizzards arrive. "It's mutton every meal out here - we chase sheep every day and eat them every meal." 

This 1960 tourism film, produced by the National Film Unit, is aimed at a particular market niche: hunter holidaymakers. It follows a visitor from Omaha, USA, ‘JD’, who flies down to the “land of countless deer”: Dart Valley in the Southern Alps. A folk song extols the joys of answering the call of the wild — “The very best thing for a man: To hunt and fish and sleep out of doors, eat his tucker where he can” — as JD and his guide climb via bird-filled beech forest onto scree slopes to nab a 14-point stag; before a ciggie on the ridge and a squiz at the scenery.

"These mountains have always been a challenge. Now there's a new type of skier facing that challenge in a new way." Across the Main Divide follows NZ mountain guide Shaun Norman, US telemark skiing champ Whitney Thurlow and German skier Babette Bodenstein, as they cross the Southern Alps in free heel skis. Flown up the Tasman Glacier from Mount Cook, a 2,000m haul up to Graham Saddle is rewarded with sweet spring snow skiing and cheesecake at Alma Hut, before the tramp down to the West Coast. The doco screened worldwide and won awards at mountain film festivals.
