Manapōuri hydroelectric power station is New Zealand’s largest. This 1970 NFU film — made for the Electricity Department — follows workers clearing a path for power through epic Fiordland mountains and rainforest, building roads and power pylons, and stringing a cable along the “hard and dirty” 30 miles to the aluminium smelter at Bluff. Sixteen men were killed constructing ‘the line’ before power was first generated in 1969. At the same time the scheme generated mass protests (the ‘Save Manapōuri’ campaign) at the proposal to raise Lake Manapōuri's level.
The bid to raise the level of Fiordland’s Lake Manapōuri (to provide hydro-electricity for an aluminum smelter) resulted in controversy between 1959 and 1972. This film charts a (still-timely) debate as arguments for industrial growth and cheap energy vie with views advocating for ecological values. New Zealand’s first large-scale environmental campaign ensued, and its “damn the dam” victory was a spur for the modern conservation movement — drawing an unprecedented petition, Forest and Bird, and figures like farmer Ron McLean and botanist Alan Mark into the fray.
