At the time of the strike, the labour movement in New Zealand was expanding rapidly. The New Zealand Federation of Labour, 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. 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 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 localpolice chief reacted cautiously to the action, but Police CommissionerJohn 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 strikers were arrested and jailed. Anger among the strikers grew, and the Federation of Labour gradually began to lose control to even more radical groups, such as the Industrial Workers of the World organisation. In October, the Company was able to re-open the mine with non-union workers. The union workers reacted angrily, and the new workers were attacked with stones. Tensions between the union and non-union workers were very high — the union workers saw the newcomers as threatening their livelihoods and as being traitors to the working class, while many of the newcomers felt they had little choice but to take what work they could find, and resented the attacks and condemnation.
Black Tuesday
The violence gradually escalated, with union workers on one side and non-union workers and police on the other. The greatest level of violence came on 12 November, known as "Black Tuesday". A group of armed non-union workers and police attacked the union hall, which was defended by a small group of union workers. Thomas Johnston, a non-union worker who had come to the mines after his market garden in Auckland was bankrupted, was shot in the knee, and a police constable was shot in the stomach. The shots were fired by Fred Evans, a radical unionist. Evans himself was struck by Constable Gerald Wade and later died of his injuries. Soon afterwards, the strikers broke ranks, with many fleeing Waihi altogether.
Aftermath
Evans was later held by the hardliners up as a hero and a martyr, with Bob Semple saying that Evans had been "doing his duty and should have shot more of them". Despite this, however, many people in the union movement actually moderated their positions after the strike — it had, after all, failed to achieve its goals. The strike also contributed to unity in the New Zealand labour movement — the Socialist Party, which had backed the strike, moved towards merger with the more moderate United Labour Party, which had not. The resultant Social Democratic Party later formed the basis of the modern Labour Party. A pamphlet The Tragic Story of the Waihi Strike was co-written by Harry Holland, Robert Samuel Ross and Francis Edward O'Flynn. The imprisoned strike leaders including Bill Parry were released in November against security of £1600; the bond was later found to have been put up by brewer Ernest Davis, who was a major source of funds for the Labour Party for half a century.
Legacy
In late 2016, the play 'Scarlet and Gold' told the story of the Waihi strike.
