This Contact episode goes behind the scenes on a big budget commercial from the early days of the Kiwi film renaissance: a 1982 Crunchie bar ad which owes so much to Star Wars, the film crew even call their villain Darth. After 12 hour days working inside the Waitomo Caves, a move to Ninety Mile Beach sees the weather playing havoc with sets and schedules. Seeking fresh faces, commercials king Geoff Dixon (Crumpy and Scotty) cast his lead actors in Australia. Television adverts were even made to announce the arrival of the ad — which plays over the closing credits.

This Loading Doc short follows cavers Dave Ellacott and Mike Allen on their mission to connect Luckie Strike and Junior Mudball, two vastly different cave systems at Waitomo. Luckie Strike features extraordinary rock formations, waterfalls, and vast caverns. Junior Mudball is as its name suggests, mostly mud. The short sees them at work, galavanting through streams, abseiling down crevasses and scraping through mud — and reflecting on what they love about it. Luckie Strike was picked by National Geographic for its Short Film Showcase. A longer version is in the works.

The Waitomo Caves are a longtime tourist magnet, thanks to their bioluminescent glow-worms and spectacular stalagmite and stalactite formations. Aside from the glories of the caves, this National Film Unit tourism film mentions the surrounding countryside as “a good reason to stay another day”. Set to a laid-back jazz score, a tour from Waitomo Caves Hotel takes in lambing, limestone outcrops, scenic driving and a picnic by the Marokopa waterfalls. But "to float down the underground river as galaxies pass silently overhead is the crowning pleasure in the valley of Waitomo.”

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.

"So the Queen comes to New Zealand. 12,000 miles from the motherland she is not among strangers. She has come to her New Zealand home." When the Queen and Prince Philip began the first tour of NZ by a reigning monarch (soon after her coronation), a National Film Unit crew followed the journey, before condensing 40 days and 46 stops into a mere 25 minutes. Along the way the newly crowned Queen wears her coronation gown to open Parliament, and witnesses geysers, long-jumpers, Māori canoes, plus masses of enthused Dunedinites refusing to keep behind the barrier.

Beloved by 70s and 80s era Kiwi kids, Spot On mixed educational items and entertainment. For the final episode, broadcast live on Christmas Day 1988, guest host Bob Parker celebrates the show’s 15 years by tracking down almost every Spot On presenter. There are also clips of fondly remembered sketches and adventures, set to pop hits of the day. The roll call of presenters includes Phil Keoghan, Ian Taylor, Danny Watson, Erin Dunleavy, Ole Maiava, Helen McGowan and the late Marcus Turner. Spot On won Best Children’s Programme at the 1988 Listener Film and TV awards.

This National Film Unit magazine film begins with a choir performing the classic 'Pokarekare Ana' in the acoustically-blessed depths of the Waitomo Caves. The second item involves a visit to a toy factory, deep in preparation for Christmas. Disembodied doll heads fill a bin, while elsewhere factory staff add eyes, and blacken the teeth of rocking horses. There are also teddy bears, electric trains and rows of toy trucks. The narrator explains the joy the toys will bring come Christmas: “a production line to delight children everywhere — fantasy from an industrial Santa Claus”.

The line “where the bloody hell are you?” generated controversy when used in a 2006 Aussie tourism campaign; so who knows what 1980 audiences made of this promo’s exhortation to “Come on to New Zealand.” But as the narration assures: “It’s a safe country. You can walk without being molested.” Aimed at the US market, the film was made as long haul air travel was opening up NZ as a destination. Māori culture, sheep and pretty scenery are highlighted, alongside skinny dipping and weaving (!). Narrated by Bob Parker, the NFU promo marked an early gig for editor Annie Collins.

This NFU short features the first 'official' colour footage of the Waitomo Caves. Perhaps wary of playing its ace card too early, Waitomo finds time to showcase local beaches and hotel ping-pong tables before moving underground. A wave of Phantom of the Opera-style organ music accompanies the tour party as they enter Waitomo’s limestone grottos, then float down an eerie underground river. Meanwhile the narrator reimagines earlier cave explorations — by English surveyor Fred Mace and local chief Tane Tinorau — into a tale of one lone white man and his candle.

This 1949 NFU film is a whistle-stop tour of Aotearoa that, per the title, takes in the full gamut of the scenic wonderland. Splendidly filmed in Kodachrome, there are lakes (Tutira, Manapouri, Te Anau, Wakatipu), caves (Waitomo), mountains (Cook/Aoraki, Egmont/Taranaki) and forests and farms aplenty, with the occasional city sojourn and an obligatory ferry shot. In the narration indefatigable nature is harnessed for man’s needs and appreciation. Of note is a sequence on gum-collector Nicholas Yakas, who shows impressive agility as he scales a giant kauri.
