Abstract: Provision of a primary health care system that delivers timely, appropriate, affordable and effective care is a challenge throughout the world. The purpose of this work is to discuss the realities of collaborative practice in primary health care, where care is delivered by doctors and nurses in general practice settings in New Zealand. The close relationship between the two professions has been historically marked by the dominance of medicine over nursing. Unclear articulation of nursing practice by the nursing profession along with historical gender issues has further hindered a more collegial relationship between medicine and nursing. The author suggests that historical gender inequalities have also contributed to a system which has disadvantaged nurses in the execution of their work. Collaboration occurs when mutual respect is present between two parties intent on furthering mutual goals. Collaboration is not supervision or co-operation. It is therefore, the author suggests, questionable that collaboration exists in the New Zealand system other than through the good will of individual practitioners. An examination of these issues using the work of Jurgen Habermas and Michel Foucault offers insight into how the current working situation between medicine and nursing came about. The author concludes that the emergence of the nurse practitioner role in New Zealand along with a change in the way that primary health care is being managed nationally provides opportunities for the nursing profession to move into emancipatory collaborative practice roles.
