Smoking is a serious health concern for Maori, particularly Maori women who have a 50% smoking prevalence rate. Nurses are ideally positioned to act as role models and facilitate smoking cessation among Maori, although a number are smokers (30%). In order to maximise the potential of Maori nurses to encourage Maori to quit smoking, a supportive intervention to assist those smoking to quit is needed. This multi-method research aims to design and develop a smoking cessation intervention suitable for use with Maori nurses. It is the first of two phases (Phase two will be a separate application to the HRC). Phase One will comprise three stages: establishment of the research and initial data collection, participatory research to design an intervention, and development of the intervention. The outcome will be a kaupapa Maori smoking cessation intervention for Maori nurses.
