A brief overview of the Green Paper on the National Health Insurance (NHI) policy of South Africa is presented. It describes the intention of the NHI to ensure equity, address the inequalities presented by the current private and public health system and present an ambitious plan to change the face of the South African health care system over the next fourteen years. It provides the context of the currents system that provides the case for the change. It also provides some detail on the structure of the proposed new Re-engineered Primary Health Care system as well as the future financing of this bold new health care system for South Africa. The challenge will be in its implementation.
