Six District Health Boards are being asked to consider a clinical services plan that would see more sharing of information and medical specialists.
A draft plan presented to the boards in the southern half of the North Island in May has been revised, with greater emphasis on strengthening community health care and clinicians working across geographical boundaries.
Hawke's Bay DHB's chief executive Chris Clarke says it is no longer clinically or financially sustainable for boards to work in isolation.
Mr Clarke says the regional clinical services plan, which would stop the fragmentation of clinical services, has a lot of merit.
Hawke's Bay DHB's commissioners will consider the revised plan on Thursday.
