Auckland-based healthcare software vendor Orion Health plans to sells its profitable Rhapsody integration engine business to British private investment firm Hg for $NZ205 million, with some of the proceeds to be reinvested in its population health and hospitals divisions and to fund a share buyback.

Orion will continue to own the hospital division outright, with Hg to take a quarter shareholding in population health, and Orion will retain a quarter share in Rhapsody.
