The Waihi miners' strike was a major strike action in 1912 by gold miners in the New Zealand town of Waihi. It is widely regarded as the most significant industrial action in the history of New Zealand's labour movement. It resulted in one striker being killed, one of only two deaths in industrial actions in New Zealand. Origins At the time of the strike, the labour movement in New Zealand was expanding rapidly. The New Zealand Federation of Labour (known as the "Red Fed"), which was linked to the Socialist Party, was gaining considerable support from the working class, and the Waihi Trade Union of Workers, to which many miners belonged, was part of the Federation. Disputes between the union and the large Waihi Goldmining Company were frequent. Miners had many grievances regarding their working conditions and often downed tools and walked off the site in response to accidents in the mine (falls, broken limbs, crushing, brusings and even the occasional fatality). A more insidious killer than the accidents was miners' phthisis, dust on the lungs. Because of 'miners complaint' as it was known, men who started mining at 16 would be lucky to reach 40. The company offered no compensation for miners and long before the strike (1906) there was a feeling among them that In May 1912, a number of stationary engine drivers who rejected the Federation of Labour's strong positions established a breakaway union. Although the Waihi Goldmining Company claimed to have no involvement in the breakaway union, saying that it was a matter of union politics, many workers believed that the Company was attempting to split the union, and called a strike. The local police chief reacted cautiously to the action, but Police Commissioner John Cullen ordered a strong response, dispatching additional police. Two months later, the conservative Reform Party came to power — the new Prime Minister, William Massey, declared that he would strongly oppose the "enemies of order". Support from other miners Several other mines around the country were affected by the action at Waihi, with miners downing tools in support of the Waihi miners or with their own claims against the harsh working conditions. At Reefton, in the South Island, this led to a lock-out of workers in June and July 1912. Confrontation The police buildup in Waihi continued until an estimated 10 percent of New Zealand's police force was present. Around 60
