This intervention study recruited 10 general practices with low immunisation coverage rates and a high percentage of the enrolled population being of Māori ethnicity. The study aim was to translate best practices from high performing general practices into strategies to improve childhood immunisation coverage in these low performing practices. The 6 intervention groups received customised action plans and support for a 12-month period; 4 control groups received ‘business as usual’ support. Key informants from all participating practices took part in structured interviews that explored current aspects related to childhood immunisation delivery. Surveys were conducted to understand how the intervention worked. Thematic analysis of the interview data revealed two positive aspects of childhood immunisation delivery: high prioritisation at the practice and staff who were pro-immunisation and knowledgeable. Key challenges cited by participants included inaccurate family contact information and discrepancies with referral processes to other providers. Other challenges included building rapport with families and vaccine hesitancy. The action plans included various strategies aimed to improve processes at the practice, contact and engagement with parents, and partnership development with local service providers. Comment: I wish more people took notice of the hard work that
