Susan Mouat is appealing her 11-month home detention sentence.
The Taranaki woman was last month sentenced for the manslaughter of her husband Bruce Mouat, six years after his death.
Mouat died after falling down the steps of his Hawera home in July 2011. He hit his head and later died in hospital.
Susan Mouat initially claimed he had come home drunk and fallen of his own accord after the pair had argued.
An initial police investigation was concluded and a Coroner later deemed the fall an accident.
