Prior to its merger with Health New Zealand in 2021, New Zealand Health Partnerships served as a public enterprise owned and operated by 20 District Health Boards. It was tasked with procurement of medical equipment, devices and services, and required all suppliers to either be a member of the Medical Technology Association of New Zealand (MTANZ) – which has an obligatory code of ethics – or otherwise adhere to the MTANZ Code of Practice which is made publicly available alongside other resources. While this structure is no longer in place in New Zealand, it illustrates that State agencies have partnered with associations to advance corporate integrity in public procurement.
