With some exceptions the striking similarities of labour history in Australia and New Zealand have traditionally been examined through the lens of separate national narratives. More recently, however, we have witnessed a recovery of the ‘trans-Tasman world of labour’. Such historical analysis has enabled the emergence of significant insights into the parallel development of labour market legislation, policy formation and wage fixation. This article charts the shared gendered experience of the labour movement between Australia and New Zealand and focuses, in particular, on equal pay. We argue that attempts to tell national stories in these two countries will be enriched by an appreciation not just of the trans-Tasman context and influences, but also of the ways in which workers have mobilised at the international level.
