A government report into violence in schools has recommended that anti-bullying programmes be made mandatory - but a school association says this will do more harm than good.
The Ombudsman's Office yesterday issued its findings after its investigation into bullying at Hutt Valley High School in 2007.
At the time, police were called to the school when nine Year 9 boys were dragged to the ground by six older students.
The acting principal said then he had no regrets about how the incident was handled and "it wasn't an assault where somebody had spilt blood".
But the school's board of trustees yesterday apologised "unreservedly" for the way the incidents were handled.
