Whanganui District Health Board has taken the first step towards drawing up a joint strategic plan with its Palmerston North-based neighbour, MidCentral District Health Board.
But Whanganui board chairwoman Dot McKinnon said there was no intent to merge the two DHBs.
Ms McKinnon said the aim of the plan was to clarify the shared services between the two DHBs.
"We already share some clinical services, leadership, governance and some support services. It is a sensible move and both DHBs can benefit from sharing services, clinicians, systems and ideas."
Ms McKinnon said the first phase of the strategic plan was a health needs assessment, which would be carried out this year.
