The cousins, then aged 17 and 14, broke into the frail retiree's Opotiki home and beat him with wooden rods, causing massive head injuries and blood loss that later led to his death.
In their initial sentencing in 2009, the court heard in the family's victim impact statement that their frail and ailing father had been savagely beaten by a neighbour to whom he had shown generosity.
"The girls that had been given oranges from my Dad's tree later proceeded to break into my Dad's house and attack him,'' the statement read.
"What kind of exchange is that?''
Justice Geoffrey Venning said Te Wini knew Mr Rowe as the "old man across the fence'' and she had suggested his house as a target for a robbery.
He said Te Wini had played a full and important part in the attack, and had been aware of Mr Rowe's age and frailty.
