Routinely collected health data has been successfully used to describe “the problem” of persisting inequalities and to inform potential ‘solutions’. However, increasing attention is now being paid to data utility and relevance. Using a kaupapa Māori approach, this three-year study will to explore how routinely collected Māori specific health data, gathered at the DHB level and reported by the Ministry of Health, can be optimally used by Māori leaders and DHB leaders and decision-makers, to stimulate improvements in health outcomes for Māori. Three case study DHBs will participate in the study conducted over three phases: an examination of current data utilisation practices; understanding facilitators and barriers to using data in health services planning; and in the translation phase, communicating successful strategies to the wider sector. The study will highlight the processes; resources; skills; and time needed to transform DHB level data into decisions and actions that improve hauora Māori.
