Abstract: This thesis examines the forces influencing the development of contemporary advanced nursing practice in New Zealand. It begins with an historical approach to explore the various meanings of advanced nursing practice from the late 1800s through the first years of the 21st century. Seven historical understandings of the meaning of 'advanced' nursing practice emerge. The author's analysis of the broad scope of New Zealand nursing history, including a case study of the development and implementation of the nurse practitioner, draws on theoretical perspectives from sociology, political science, and nursing. She develops a “framework of critical factors for nursing to take into account when considering how to ensure the profession is able to deliver on its great potential to improve the health of New Zealand communities”. Examining the work of a range of nursing leaders, past and present, and drawing on the work of political scientist, John Kingdon, the author describes the work of several nurses as “policy entrepreneurship.”
