On a holiday to Mt Tarawera with her scientist parents, teenager Jenny (Katrina Hobbs) finds an odd shard of metal. By touching it she unwittingly awakens 'Drom' — a survivor of an alien mission to deactivate a planet-annihilating space gun (aka the volcano!). Local kids Tessa and Lloyd also own key pieces; if Drom and the teen trio can't defeat the gun-toting mechanoid ... human and alien species extinction is imminent! The internationally successful six part series was a South Pacific Pictures and Canadian co-production; it screened in 1991.

Classic sci-fi TV series Under the Mountain follows the adventures of redheaded twins with psychic powers — Rachel and Theo — on their Auckland summer holiday. They meet the mysterious Mr Jones, an alien emissary who enlists them in the battle against the evil Wilberforces, who are plotting planetary destruction. Adapted from the Maurice Gee novel, the series' fx left their slimy imprint on a generation of NZ kids, haunted by the transmogrifying Wilberforces, who changed from humans into giant slugs slithering underneath Auckland’s volcanoes.

Two 14-year-old girls discover that they have a lot in common in this two-part 1995 children's fantasy drama. They live in the same street, same house, same bedroom, but 76 years apart. An antique mirror/portal leads them on a time travel adventure involving nerve gas, a Russian Tsar and an English soldier. Created by Australian Posie Graeme-Evans (who devised TV hits Hi-5 and McLeod's Daughters) this award-winning trans-Tasman co-production between the Gibson Group and Millennium Pictures was sold to more than 60 countries. A second series followed in 1997.

After adapting the slimy transmogrifying Wilberforces of Maurice Gee novel Under the Mountain for the small screen, scriptwriter (and future sci-fi novelist) Ken Catran returned with his own tale of kids and extraterrestrial contact. The series follows holidaying teen Gretchen (Sarah Dunn) trying to unravel the mystery of a weathervane — a "daisy rod" which seems to have otherworldly powers — and curious objects found in a tapu swamp. Backing up this girl-power sci-fi adventure are Catherine Wilkin, Roy Billing and Utu star Zac Wallace.

The titular kids are a crime-fighting duo of physically-disabled teenagers working for O.W.L. (Organisation for World Liberty) in the battle against the evils of S.L.I.M.E. (Southern Latitude's International Movement for Evil!). With laser beam-firing crutches and computerised wheelchairs at their disposal they inevitably outwit the bumbling crooks. Made in Christchurch, the fondly-remembered kids' show was created by Kim Gabara and screened for two series. Neon alert: Apple aficionados will note the early use of graphics from Apple 2 and Apple 3 computers.  

This children's post-apocalyptic fantasy series follows a circus troupe, Maddigan's Fantasia on their quest to save the world's only remaining city, Solis. The show was created by children's writer Margaret Mahy, developed for television by writers Gavin Strawhan and Rachel Lang for South Pacific Pictures, who produced the 13 x 30min series for TV3. Award-winning and successfully exported, it marked a debut lead performance from Rose McIver (future Tinker Bell in US TV show Once Upon a Time) acting with Michael Hurst, Peter Daube, Tim Balme and Danielle Cormack.
