This 1948 documentary follows 24 hours of work on the railways. It was directed for the National Film Unit by New Zealand’s first female film director, Margaret Thomson. It shows the engines and commuter trains preparing to leave Wellington, and the overnight train arriving from Auckland. Workers toil on the railway lines above the remote Waimakariri Gorge, and the town of Otira gets ready for a dance. The final shots are of an engine coming through the dawn and back to the city.

This collection celebrates women and feminism in New Zealand — the first country in the world to give all women the vote. We shine the light on a line of female achievers: suffrage pioneers, educators, unionists, politicians, writers, musicians, mothers and feminist warriors — from Kate Sheppard to Sonja Davies to Shona Laing. In her backgrounder, TV veteran and journalism tutor Allison Webber writes how the collection helps us understand and honour our past, asks why feminism gets a bad rap, and considers the challenges faced by feminism in connecting past and present.

This collection celebrates rugby in New Zealand as it has been seen onscreen: from classic bios and tour docos, to social history, dramas and protest. In the accompanying backgrounders, broadcaster Keith Quinn looks at the on air history of rugby in NZ; and playwright David Geary asks if rugby is a religion, and argues it is a good test of character.

This collection celebrates Kiwi comedy on TV: the caricatures, piss-takes, and sitcoms that have cracked us up, and pulled the wool over our eyes for over five decades. From turkeys in gumboots and Fred Dagg, to Billy T, bro'Town and Jaquie Brown. As Diana Wichtel reflects, watching the evolution of native telly laughs is, "a rich and ridiculous, if often painful, pleasure." 

For this screen showcase of NZ visual arts talent, critic Mark Amery selects his top documentaries profiling artists. From the icons (Hotere, McCahon, Lye) to the unheralded (Edith Collier) to Takis the Greek, each portrait shines light on the person behind the canvas. "Naturally inquisitive, with an open wonder about the world, they make for inspiring onscreen company."

Brian Brake is regarded as New Zealand's most successful international photographer. But before heading overseas to work for photo agency Magnum and snapping iconic shots of Picasso and the Monsoon series for Life magazine, he was also an accomplished composer of moving images. He shot or directed many classic films for the NFU, including NZ's first Oscar-nominated film. 

Labour Day commemorates the struggle for an eight-hour working day. Kiwi workers were among the first in the world to claim this right — in 1840, carpenter Samuel Parnell won an eight-hour day for workers in Wellington. This collection brings together 20 titles that involve Kiwi working life: from economic revolutions and an industrial dispute negotiated live on air (Post Office Go Slow), to public service comedy Gliding On and a portrait of union leader Ken Douglas.

More than 100,000 New Zealanders served overseas in World War l. Over 18,000 died; at least 40,000 more were wounded. Campaigns involving Kiwis, from Gallipoli to the Western Front, were identity-forming, and the war's effects on society were deep. The World War l Collection is an evolving onscreen remembrance. Military expert Chris Pugsley writes about the collection here. 

Florian Habicht first won attention for 2003's Woodenhead, a fairytale about a rubbish dump worker and a princess. By then Habicht had already made his first feature-length documentary. Many more docos have followed: films that celebrate his love for people, and sometimes drift into fantasy. In this collection, watch as the idiosyncratic director meets fishermen, Kaikohe demolition derby drivers (both watchable in full), legends of Kiwi theatre and British pop, and beautiful women carrying slices of cake through New York. Ian Pryor writes here about the joys of Florian Habicht.

In 2000 the Employment Relations Act was passed into law in New Zealand, replacing the Employment Contracts Act. The bill proved controversial: some suggested it placed unfair obligations on employers, while others claimed it restored much-needed rights to workers that had been undermined. This Assignment episode explores both angles. Among them, business owner John Holm argues that he shouldn’t be told how to treat his employees, while union leaders and Alliance Party MP Laila Harré all argue that without the bill, workers will continue to be exploited.
