For Kiwi-Chinese soldier Victor Low, World War I was fought mainly underground. Dunedin-born Low was a surveyor attached to the New Zealand Tunnelling Company, which created a network of caverns and tunnels in France before the Battle of Arras in April 1917. The complex was big enough to accommodate 12,000 soldiers and equipment. This episode of Great War Stories uses archive footage and modern laser scanning to map out the tunnels that still exist under the battlefield. Later, Low helped create the famous Bulford Kiwi which sits above Sling Camp in England.

Kerre McIvor (then Kerre Woodham) hits Cambodia in this full-length Intrepid Journey. After sampling Vietcong tunnels in Vietnam, the self-confessed lover of home comforts crosses the border and confronts Cambodia's rough roads. Feeling guilty about complaining in a country that has endured so much, she is moved by the strong and joyful spirit of the people: 'they don't need pity, they just need a break.' Woodham visits former Khmer Rouge prison S21, makes a friend at "the Queen of Cambodian ruins", Angkor Wat, and has a memorable visit to an isolated, decaying French hotel.

This special edition of the National Film Unit’s monthly magazine series looks at some of the “people, places and events filmed by our cameramen during the years 1941 - 1962”. The NFU’s 21st birthday review — compiled by David H Fowler — ranges from wartime newsreels to the post-war boom (factories, dams, industrial agriculture), from salvos to Peter Snell. Other images include Kiwi soldiers playing rugby in Korea, and cigarettes hanging from the lips of firemen fighting Christchurch's Ballantyne Department Store fire in 1947.

This documentary unearths the story of the soldiers in the New Zealand Tunneling Company, whose daring World War I raids involved digging tunnels through chalk rock, laying explosives underneath enemy lines, and countermining German tunneling efforts. The story is told through the eyes of a New Zealand woman who retraces her grandfather’s war story to Arras, France, and sees the Kiwi-tagged cavern 'city' nearly 80 years later. The company played a key role on the Western Front, and was especially recruited in NZ, made up of miners, bushmen and labourers.

This third episode in presenter Peter Hayden’s journey across latitude 45 depicts the “new gold” of the booming tourist trade. On the Clutha River, archaeologists race ahead of the construction of a dam, digging for a soon-to-be-submerged mining past. The road to Skippers Canyon induces vertigo. Hayden rafts through the Oxenbridge brothers’ tunnelling feat, a failed project aimed at diverting the Shotover River in the hope of finding gold on the exposed bed. Alan Brady is filmed in his newly-established winery, the first in a region now famed for its wine.

This eighth episode in the Landmarks series was the first episode filmed, to test how geographer Kenneth Cumberland handled being in front of the camera. On a Cook Strait ferry in a southerly, he begins exploring how trade and people have gotten about Aotearoa: from the “Māori main trunk line” (beach, water), sailing ships, Cobb & Co and ‘Shanks's Pony’, to the railways and Bob Semple’s roadmaking bulldozers.The episode ends with the national grid and airways, with a rocky landing at Wellington airport demonstrating that the wrestle with place is an unresolved one.

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.

A young boy is afflicted by apocalyptic visions in medieval Cumbria. Believing he is divinely inspired to save his village from the Black Death, he persuades a group of men to follow him into a tunnel. They dig deep into the earth and emerge ... in Auckland, New Zealand, 1987. Following portents, the time travelers must negotiate the terrors of a strange new world, (motorways, nuclear submarines) — while seeking to save their own. Nominated for the Palme d'Or at Cannes, it scooped the gongs at the 1988 AFI and 1989 NZ Film & TV Awards.

Produced by NHNZ, this NZ Screen Award-nominated 2005 TVNZ series looks at Aotearoa’s diverse weather. This first episode (of three) explores "the main driving force behind all our weather" — the wind — from the science behind where it comes from, to its impact on people (from sport to the economy). Presenter Gus Roxburgh contends with Wellington’s infamous wind, and with Auckland’s tornadoes and cyclones. He looks at when weather is good (wind farms, windsurfing) and when weather goes bad (the Wahine disaster, Cyclone Bola, landing at Wellington Airport). 

On land, sea and air during World War II, and from Korea to Vietnam, this group of old soldiers remember their years of service. Close calls are common place but often laughed off, but the horror of war is often close to the surface. The third series of interviews from director David Blyth (Our Oldest Soldier) and RSA museum curator Patricia Stroud provide a valuable archive of a time now almost beyond living memory — particularly World War II, as the veterans enter their 90s and beyond.
