Smith passed away in hospital after being found in her home suffering septic shock, multiple organ failure, severe pressure sores and malnourishment.
The 54-year-old had been found to be living in squalid conditions in her own home, largely confined to a cane chair, while under the care of the National Disability Insurance Scheme.
Maione, 69, pleaded guilty to Smith’s manslaughter and was earlier this month sentenced to six years and seven months in prison.
NDIS Quality and Safeguards Commissioner Tracy Mackey said Smith’s death is “tragic and continues to shock and sadden many xjmtzywpeople across Australia”.
“NDIS providers have very clear obligations and we will take action when providers do not meet those obligations,” she said in a statement.
