"This is a most serious case of elder abuse and a system should have been in place to ensure that people like Mrs [Maureen] Quinn are at least monitored over a regular period of time.
"It shows that there are people just being appallingly neglected. I followed the case and thought it was most alarming to think this was going in New Zealand of all places."
Medical staff discovered Maureen Quinn, 82, in November 2011 in her home in Marewa, where she had lived for 60 years and raised eight children.
She died of bronchial pneumonia six weeks after she was found by medical staff.
"I can't believe I had eight children and I've ended up in this state," she told them.
Joanne was her eldest daughter and sole carer.
University of Auckland Associate Professor of Law Bill Hodge said had the woman had died at home instead of in hospital six weeks after being found, Quinn could easily have been charged with manslaughter, which carries a maximum penalty of life imprisonment.
As it stands, she faces a maximum seven-year sentence.
"I think she will receive a sentence of a couple of years in prison unless she can prove her brothers and sisters overtly refused to help," Hodge said.
