Dementia NZ has welcomed increased monitoring of private dementia facilities after "horrifying" cases.
Paul Sullivan, chief executive of the charitable trust, said enabling the Ombudsman to inspect facilities was a much-needed step in the right direction.
"Some of the treatment in facilities that has been exposed is horrifying. It's vital that staff in dementia units are trained properly and treat people with dementia with respect and compassion," Sullivan said.
"Hopefully this monitoring will help highlight when that isn't happening."
The Office of the Ombudsman will have the power to randomly inspect about 180 privately-run dementia facilities, including those contained within aged care facilities and rest homes, in changes gazetted by Justice Minister Andrew Little this week.
