Inequities in health status exist in New Zealand across the rural–urban spectrum. In parallel, rural–urban differences in health service utilisation vary by service type. Despite the New Zealand public health system being based on principles of universal access, equity and fairness, levels of health expenditure on rural and urban populations are not well understood. The purpose of the study is to undertake a rural–urban analysis of public health system expenditure, based on individual-level service utilisation and national pricing of health service events.

Individual-level service utilisation and pricing will be collated from national collection databases for all eligible users of publicly funded services. The analysis will include calendar years 2017–2024. Descriptive analysis and a two-part generalised linear regression model will be used to identify if rural–urban differences in expenditure exist, and what the association of rurality is with expenditure (if any). The model will also be used to identify geographic regions with expenditure levels that vary from those predicted using regression model weights. As the specific statistical approach will be determined by data attributes, this protocol outlines the intended approach to construct the analytical model.
