Racism is an important social determinant of health that underpins ethnic and racial health disparities. This study seeks to provide a comprehensive understanding of the impacts of racism on adult health and wellbeing, and ethnic inequalities in New Zealand. Specifically, we aim to look at experience of racial discrimination for different ethnic groups (Maori, Pacific, Asian, European); if any changes have occurred over time; whether experience of racism is linked to poorer health and wellbeing measures, including healthcare; and how different forms of discrimination combine with racism to affect peoples' health and wellbeing. This will be undertaken through a comprehensive analysis of secondary data from multiple national surveys, including the New Zealand Health Survey (2002/03, 2006/07, 2011/12) and the General Social Survey (2008, 2010, 2012). Study findings will inform anti-racism and public health interventions in ongoing efforts and actions to improve health and eliminate ethnic health inequalities.
