Reform and counter reform: How sustainable is New Zealand&s latest health system restructuring?

New Zealand's health care sector has undergone almost continual restructuring since the early 1980s. In the latest set of reforms, 21 district health boards (DHBs) have been established with responsibility for promoting health, purchasing services for their populations and delivering publicly owned health services. Boards will be governed by a mix of elected and appointed members, will be responsible for arranging the delivery of primary and community health services, and will own and run public hospitals and related facilities.

We clarify the differences and continuities between earlier reforms and the 2000/01 structures, as well as the current reforms’ potential strengths and weaknesses. The paper discusses whether the DHB model was the only feasible option for restructuring and whether the dynamics of the new system may lead to further changes, particularly on the purchaser side of the system. Given that DHBs face potential conflict between their purchasing and provision roles, and given the potential advantages that primary care organisations may have as purchasers, we conclude that it is possible that all or part of the purchasing function of DHBs might eventually shift to primary care organisations, leaving the DHBs as hospital-based provider organisations.
