Riddled with old military tunnels, Auckland’s North Head has long been the focus of speculation. In this documentary Philip Alpers explores theories that a hidden tunnel network contains tonnes of decaying ammunition — and two old Boeing airplanes. Archeologist Dave Veart sets about finding the truth. The man responsible for closing the tunnels says there's nothing there; others recall seeing a plane. Filmmaker John Earnshaw is convinced of its existence. Earnshaw would spend years battling the crown in court, over claims of a breached agreement to search North Head.

In 1995 Flying Nun released compilation CD Abbasalutely, made up of ABBA covers from their stable of artists. Headless Chickens contributed with this decidedly heavy cover of 'Super Trouper', ABBA’s ninth and final UK chart topper. The monochrome music video for the remake takes place at the RNZAF Base at Whenuapai, with the Chickens adopting many precarious positions on top of aircraft. It was directed by Jonathan Ogilvie, who helmed numerous Flying Nun music videos. The song's title was inspired by a popular concert spotlight.

Kiwi-born Keith Park commanded the Royal Air Force division which defended London during the Battle of Britain. His command is dramatised in this Greenstone telemovie. Historians Stephen Bungay and Vincent Orange offer accounts of what happened, alongside archive footage from World War ll. This excerpt sees Park hosting Winston Churchill as his forces are stretched to breaking point by a German attack. After returning home, Park went on to chair the Auckland International Airport Committee and serve as an Auckland City Councillor. John Callen directs and narrates.

This 1949 episode of the National Film Unit’s Weekly Review newsreel series goes on a jaunty whistle-stop tour across the country. It takes off on TEAL’s new flying boat (Ararangi), from Wellington’s Evans Bay on a cruise over to the Marlborough Sounds and back. We then stop to smell the tulips on a South Canterbury tulip farm; before revving up for dusty motorhead bliss in Whanganui as a swarm of motorcyclists contest the Motorcycle Grand Prix. The reel pulls up in an Auckland factory for a fascinating look at the manufacture of glamourous nylon stockings.

Made by the NZ Broadcasting Corporation in the mid 1960s, this half hour TV documentary sets out to summarise New Zealand. More than a promotional video, it takes a wider view, examining both the country’s points of pride and some of its troubles. In a brief appearance Barry Crump kills a pig, although the narration is quick to point out that the ‘good keen man’ image he epitomises is also a root of the country’s problem alcohol consumption. The result is patriotic, but certainly not uncritical. Writer Tony Isaac went on to make landmark bicultural dramas Pukemanu and The Governor.
