Four prisoners have been injured, one seriously, after a Corrections van crashed on State Highway 1 in Atiamuri, north of Taupō.
Brigid Kean, acting Deputy National Commissioner, told The Herald the van crashed while transporting prisoners between Rimutaka Prison and Spring Hill Corrections Facility.
There were two staff members and four prisoners in the vehicle.
"All four prisoners were taken to hospital for medical assessment and treatment of their injuries, which are not life threatening," Kean said.
"Once they have been cleared by the hospital they will be returned to custody and offered a call to their next of kin to let them know that they are safe."
