This short 1979 National Film Unit documentary heads up the steep bush-clad West Coast valleys from Rūnanga, to profile the men at work at five private coal mines. Director Conon Fraser (Looking at New Zealand) showcases the remarkable DIY resourcefulness required by the small groups of miners. The rugged individuals work the seams, push bins along steep incline railways and dump the loads down vertiginously steep flumes. At the time this film was made waning prospects for the unique way of life were looking up, as high oil prices spurred demand for coal. 

People of the Waikato makes frequent pitstops along the 425 km path of NZ's longest river. Made in an era of post-war electricity shortages, the film balances requisite beautiful scenery with excursions into the Waikato's extensive hydroelectric system: including then-unfinished fourth dam Whakamaru, whose development was slowed by the discovery of clay in the foundation rock. Alongside brief glimpses of those who live and work on the river, there is footage of stunt-filled canoe races, Turangawaewae Marae, and a veteran boatman tugging coal. 

Train enthusiast David Sims captured the dying days of steam trains in this 1968 National Film Unit short. It features arresting images of a Kb class locomotive billowing steam as it tackles the Southern Alps, en route from Canterbury to the West Coast. Kb Country was released in Kiwi cinemas in January 1968, just months before the steam locomotives working the Midland Line were replaced by diesel-electrics. Sims earned his directing stripes with the film. As he writes in this background piece, making it involved a mixture of snow, joy and at least two moments of complete terror.
