The development of the political labour movement in Christchurch is considered for the period 1914-19. The nature of social stratification in the city is explored. The influence and importance of trade unions, social activity, the prohibition agitation, conscription, inflation and the movement for workers' education are then examined. It is argued that each had an impact on forging the identity of the party by the end of the First World War. By 1919, Christchurch Labour was a 'class' party, in character and configuration of support from within the community. It drew upon the traditions of an evolving indigenous class consciousness.
