Hospitals manager Nick Saville-Wood will lead Lakes District Health Board while a new chief executive is recruited.
The district health board chief operating officer will lead the organisation for a fixed period when retiring chief executive Ron Dunham steps down at the end of December.
Saville-Wood manages Rotorua and Taupo Hospitals along with a number of community services. He led the rebuild of both Rotorua and Taupo Hospitals in his previous role as general manager of corporate services and as the project director for the hospital's redevelopment that ended in 2014.
Board chair Deryck Shaw said Saville-Wood had been seconded to the chief executive role for up to six months while the district health board went through recruitment for a permanent chief executive.
