Premier William Massey's "heavy-handed" suppression of the Waihi miners' strike prompted another attempt at unity in 1913. This time, the Socialists were willing to attend. A new group, the Social Democratic Party, was formed, merging the United Labour Party and the Socialist Party. A faction of the United Labour Party refused to accept the decision, however, and continued on under the same name. Later, a decision by the Social Democrats to support a strike of dockworkers and coal miners resulted in a number of Social Democratic leaders being arrested, leaving the party in disarray in the 1914 election, the remnants of the United Labour Party actually won more seats than the "united" Social Democrats.
