In 1970, Government considered raising the Manapouri lake by 8.2 metres to maximise the Manapouri power station's output. This was met with considerable protest by the public since raising the lake level would drown large areas of native bush. 'Save Manapouri' share certificates like this example, were one of the most successful elements of the protest campaign. These certificates sold at 50 cents a share and helped raise funds for the protest campaign.
How successful was the Manapouri lake level protest?
