Māori women are disproportionately affected by HIV/AIDS in New Zealand. While making up only 14.6% of the population, Māori account for 7.2% of all recorded HIV cases in 2008 and 11.5% in 2007. Social and economic factors increase Māori women's vulnerability, including poverty, stigma, discrimination, lack of access to healthcare, and high rates of other STIs. Cultural taboos also prevent open discussion of sexuality and prevent women from disclosing their status. More research is needed to understand the impacts on Māori women and develop interventions to reduce infections and stigma.
