Developing methodological approaches to tracking historical trauma

Project Summary 

Extensive international scholarship demonstrates Indigenous people are particularly and uniquely affected by historical trauma through colonisation. Specific acts of oppression that remain unaddressed often result in the intergenerational transfer of trauma and trauma responses. 

In Aotearoa New Zealand, one such act of oppression was the forced removal of Māori children from their families to be placed in a range of state and church managed institutions often for spurious reasons. A recent Royal Commission of Inquiry was undertaken to investigate what happened to children, young people and vulnerable adults in State and faith-based care in Aotearoa New Zealand between the years 1950-99.  

This project sought to develop appropriate Kaupapa Māori methodological approaches to track those affected by this specific act of historical trauma, any compound effects on the survivors and any intergenerational effects. The research explored utilisation of existing statistical and other data sets, such as the IDI (Integrated Data Infrastructure) to highlight the trauma responses (and resiliency factors) of those who experienced abuse in care and any traceable intergenerational transmission of trauma to subsequent generations.
