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.

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.

Director Grahame McLean uses the notorious (then recent) 'Mr Asia' drug smuggling saga as fodder for this Wellington underbelly tale. Hello Sailor’s Harry Lyon headlines as a musician and ex-con who partners with a beautiful journo to investigate a global drug syndicate, in between nightclub sessions with fellow musos Beaver and Hammond Gamble. High on 80s guitar licks, Should I be Good? was made in the tax break era without Film Commission investment. McLean followed it right away with The Lie of the Land, becoming a rare Kiwi to make two movies back to back.

Three friends tour the Wellington pub scene, playing pool with ever-increasing stakes. Then they enter a tournament run by vicious crime boss ‘Daddy'. Narrator Kirk Torrance (Outrageous Fortune) guides us through their mission to pocket the money. Hamish Rothwell's only feature to date was a Kiwi take on the UK urban underbelly genre (Lock, Stock etc). "Smart, stylish and effortlessly entertaining" (Dominion Post) the film was a hit with young males and won several 2001 NZ Film and TV Awards (including best director, script, and actor). It sold to over 30 countries.

This short film follows Vincent (Leighton Phair), a young Chinese-Kiwi rescued from a group of racist punks in a spacies parlour by a mysterious Asian (Gary Young), then drawn into a seedy Triad underworld. Vincent is struggling with his identity in a mixed race family. Directors Stuart McKenzie and Neil Pardington wrote the story with playwright Lynda Chanwai-Earle, drawing it from interviews with members of the Chinese community in Wellington and Christchurch. Early 90s Flying Nun bands feature on the score; DJ Mu (future Fat Freddys Drop frontman) cameos as a punk.

Shot on location in Wellington, often after dark, Inside Straight helped usher in a new era of Kiwi TV dramas, far from the rural backblocks. This Minder-esque portrait of Wellington’s underworld was inspired by writer Keith Aberdein’s experiences as a taxi-driver and all night cafe worker. Phillip Gordon (soon to win fame as a conman in Came a Hot Friday) stars as the former fisherman, learning the ways of the city from veteran taxi driver Roy Billing. A solid but unspectacular rater over 10 episodes, the show was scuttled by the launch of trucker’s tale Roche.

Director Peter Salmon's sci-fi short is set in a dystopian future where citizens spend most of their lives in virtual reality to escape the bleak Blade Runner-like offline world. Grace (Sara Wiseman, in a NZ Film Award-winning performance) is a lonely programmer looking for cyberspace love via Angelife: a fantasy-fulfillment site with "five billion connections worldwide". Disenchanted with her Adam (Rupert Cocks), her desire for real world connection, plus a chance meeting, push her into a dangerous underworld. Ray Woolf cameos as a winged Angelife agent.

This final installment of Hayden’s traverse across latitude 45 finds him in the ice-sculpted isolation of Fiordland. In this episode he travels through diverse flora (lush and verdant thanks to astonishingly high rainfall); and with botanist Dr Brian Molloy follows the footsteps of early bird conservationist Richard Henry. Mohua (yellowhead), takahe, weka and tiny rock wrens feature in the fauna camp. Reaching the sea, the underworld depths of George Sound house a world teeming with abundant life.

There's panic on the streets as 19-year-old tearaway Ska (Matthew Hunter) comes to terms with love and death in Auckland's 80s urban underworld. After an ultimately tragic attempt to 'rescue' his prostitute sister, Ska plots revenge at a rock gig ... with riotous results. Directed by Bruce Morrison when broken glass was still on the ground from the Queen Street riot, the film was inspired by a story from 16-year-old Richard Lymposs. In this teen spirit-infused excerpt, street-fighter Ska saves rich girl Stacy (Kim Willoughby), and meets her classy parents.
