This research project explores rangatahi Maori perceptions of STI testing and treatment to develop an intervention to increase effective testing and treatment in the Waikato. The rationale is the high rates of STIs experienced by young Maori men and women in the Waikato. Untested and untreated STIs significantly affect the self-esteem and wellbeing of rangatahi Maori as well as causing infertility. Te Puawai Tapu will partner with a Waikato-Tainui affiliated Maori youth health organisation to consult with rangatahi Maori who have tested positive for an STI, as well as consulting with Maori community groups and local sexual health organisations. Using a kaupapa Maori qualitative methodology, the research will explore rangatahi perceptions of STI testing and treatment, with a focus on service barriers. The intervention will be delivered by sexual health organisations delivering clinical and health promotion services in clinics and schools the Waikato.
