Blackball is a small town on the West Coast of the South Island of New Zealand, approximately 29 km from Greymouth. Elevation is approximately 100 metres. Blackball was a centre of New Zealand radicalism and workers' militancy. It is credited as the birthplace of the New Zealand Labour Party, which followed the 1908 miners 'cribtime' strike, at ten weeks the longest in New Zealand history. In the 1913 Great Strike, Blackball miners were the last to return to work, in 1914.
