This kaupapa Māori project addresses one of the most devastating impacts of colonisation in Aotearoa – the forced institutionalisation of Māori children between 1950–1999. Drawing on the Abuse in Care Royal Commission of Inquiry and leveraging large-scale data sets like the IDI, this study developed innovative methodologies to trace historical trauma and its intergenerational effects. Without burdening affected whānau through direct contact, the research seeks to highlight systemic harm, measure outcomes such as reduced life expectancy, and support future tools of justice, healing, and whānau empowerment.
