Abstract: The concept of cultural safety offers a unique approach to nursing practice, based on recognition of the power differentials inherent in any interaction. Clarification of the concept is offered, together with a review of the historical shift in nursing attitudes that has led to the emergence of “cultural safety” as a viable and valued component of nursing practice. The argument is made that cultural safety has allowed for a more reflective, critical understanding of the actions of nursing to develop. This includes recognition that nurses' attitudes and values have inevitably been influenced by social and political forces, and as such are in part reflective of those within the wider community. Comparison between the support given by nurses in the early 1900s to the theory of eugenics and the current acceptance of cultural safety is used to highlight this point. An examination of the literature identifies that ideological and conceptual changes have occurred in the approach of Aoteaoroa/New Zealand nurses to issues with cultural implications for practice. A review of background factors relating to Maori health status and the Treaty of Waitangi is presented as a necessary context to the overall discussion. The discussion concludes with an acknowledgement that while the rhetoric of cultural safety is now part of nursing culture in New Zealand, there is no firm evidence to evaluate its impact in practice. Issues identified as impacting on the ability to assess/research a concept, such as cultural safety, are discussed. For cultural safety to become recognised as a credible (and indispensable) tool, it is necessary to further examine the “end-point” or “outcomes” of the process.
