A senior social worker for the Auckland District Health Board had said in a court document that Mr Pinder had significant cognitive impairment, and lacked insight into his plight, which Ms Zhang disputes.
Mr Pinder has had chronic heart failure, high blood pressure, eye disorders, a recent hip fracture and has a pacemaker and some compression fractures, and is confined to a wheelchair.
Yesterday Mr Pinder told the Herald he was being well cared for at the nursing home, but still hoped to "go home soon". Nurse manager Jane Wager felt he was better off at Radius St Joans, where he was getting 24-hour nursing care.
"We are all focused on rehabilitation and getting John feeling better," Ms Wager said.
"We can't let him go home because of the court order, but there's always a chance of that happening in the near future."
