Abstract: Analysis of the research literature on prison nursing revealed a paucity of research, both in New Zealand and internationally. The aim of this research was to describe the working life of the nurse in a New Zealand prison and provide an understanding of and documentation on prison nursing in New Zealand. A qualitative descriptive study was undertaken to determine what it is like to nurse in a New Zealand prison. Ten nurses working at two public prisons and one private prison took part in the study. Data was collected by the use of semi-structured interviews and analysed thematically into four main themes. The participants' descriptions of their working lives as prison nurses expose the multifaceted nature of this work and the inherent relational dynamics. These dynamics determine the nurse's ability to practise effectively in the prison setting. Findings highlighted many paradoxical situations for nurses when working in this environment. The very aspects of the work that participants described as negative were also identified, in some instances, as challenging and satisfying.
