Wairarapa District Health board will get its own chief executive after more than two years of the boss being shared with Hutt Valley.
Wairarapa and Hutt Valley DHBs will appoint separate chief executives to help address the "unique" health challenges of their regions.
The announcement follows the news last week that Graham Dyer, the chief executive for both DHBs, was stepping down at the end of April.
Wairarapa last had a separate chief executive in 2012, under Tracey Adamson.
Dr Derek Milne, chairman of Wairarapa DHB, said there were different pressures and demands in each DHB.
