The purpose of this impact evaluation was to assess the impact that Family Start participation is having on the wellbeing of New Zealand children and their whānau. The evaluation examined a range of health, educational, and social outcomes for children, including separate analyses for Māori and Pasifika children. The evaluation was informed by a Bridging Cultural Perspectives approach which comprises the He Awa Whiria and Negotiated Spaces models. Reviewers representing the three knowledge streams (Māori, Pasifika, Pākehā) worked together to assist with the interpretation of the findings at an aggregate level, and through the lens of each worldview.
