A report on residential aged care has admitted abuse of the elderly is a significant problem.
The report carried out for the Canterbury District Health Board discusses the challenges and risks that arise in aged care, particularly residential care for the elderly.
It says elderly people are at risk of receiving poor quality of care, and even being neglected, when their carers are under stress.
It also draws attention to institutional abuse, such as an instance at the Belhaven rest-home in Epsom, Auckland, where an elderly woman had her mouth taped shut.
The Canterbury DHB is currently investigating complaints that Christchurch's Villa Gardens rest home is not adequately caring for its patients.
