Abstract
BACKGROUND: New Zealand's District Health Board reform (2000-2022) was underpinned by the goal of reducing inequities in health outcomes between population groups and improving health overall. A key policy vehicle for achieving the goal was a system-wide shift to population health with increased strategic focus on and investment in primary health care. METHODS: This research explored shifts in power and resource to understand how equity as a policy goal for primary health care fared over the District Health Board era, and examined how the distribution of power and resources in the health sector changed for PHC over the period 2000-2020. The study used an exploratory case study methodology based on insights from key informant interviews. RESULTS: The study found that despite policy intent, actors holding political power shaped health outcomes under the reforms, curtailing the mechanisms that could have made a significant impact on equitable health outcomes between population groups. CONCLUSION: It concludes that exploring power and resource shifts sheds light on power dynamics within a reform. Since power shapes how resources are deployed, attention to power and resource complements technical elements of health system reform, by helping to understand where and how to intervene so that reforms achieve their desired goals.
