Prof Peter Crampton (Dean and Head of Campus, University of Otago Wellington) specialist in public health medicine, argues that public health is a social, political, economic and justice issue, not a medical one. After charting the course of change to our health system since the 30’s, he urges every citizen to articulate in all their relationships (personal, professional, civil), their commitment to public health as a right of citizenship. He also agues that the goal of the public health system is to reduce inequalities and produce just outcomes for all New Zealanders. http://dosomething.org.nz
