Shareholders at the private hospital operator Wakefield Health voted at their annual meeting on Friday to change the name and branding of the company.
The company will be renamed Acurity Health Group Ltd to reflect its changing operations over the last financial year, during which it acquired two new hospitals in Tauranga and Auckland.
Wakefield Health chief executive Andrew Blair says the change will allow doctors and staff at Wakefield Hospital to reclaim the brand.
The company also announced initial plans to redevelop its health campus on the site of Wakefield Hospital.
It will seismically strengthen some existing buildings and also look at options for expanding facilities.
