Police have charged a former worker at the Belhaven Rest Home in Auckland with assault.
Auckland District Health Board terminated its contract with the Epsom rest home on Thursday, two weeks after a tradesman photographed a resident with her mouth taped shut.
A woman, 60, was arrested in Auckland on Friday and will appear in the District Court next week. She was dismissed from her job shortly after the incident occurred.
Seven out of the 10 residents at Belhaven have been moved to new homes.
The Ministry of Health has not yet decided whether the home's certification will be withdrawn.
The Government has told the ministry to conduct a full check on rest homes they may have concerns about, following the incident at Belhaven.
