In this paper, we use research with Indigenous Maori women to explain the research interface to bring together Indigenous and Euro-Western ways of knowing. Our research required using an Indigenous research methodology that drew on traditional cultural knowledge with embedded critical and decolonisation theories to understand this often-marginalised group of Indigenous women. Constructivist grounded theory provided a systematic and rigorous approach to generating theory. Because of the unique histories of colonisation and contemporary realities resulting in Indigenous women's marginalisation, globally, we argue research must be relevant, safe, and meaningful to those researched to produce transformative knowledge. Therefore, planning a research methodology to inform research with Indigenous women that counters current unhelpful constructions required careful consideration. We share how we used kaupapa Maori research methodology and constructivist grounded theory to generate an explanation of how Maori women keep safe in unsafe relationships.
