Four harrowing victim impact statements were read to the court, two by prosecutor Chris Macklin.
There was emotion in his voice as he read one from the deceased's son Keanu Ngamotu, which told of his heart being shattered into a million pieces by his mother's death.
"I lost my heart, my backbone that day," Mr Ngamotu's statement said.
Sobbing, Lisa-Anne's partner Chopper Martin faced the dock and told Ngamotu "my partner paid your debts with her life, you need to take ownership of what you did and the precious life you took from us".
Justice Hinton described the statements as harrowing. When Ngamotu became agitated in the dock she allowed another sister to move from the public gallery to sit with and comfort him.
She noted he had suffered three strokes, including one while in custody on remand.
"I have serious concerns whether your health issues have been addressed in prison from the way you have been conducting yourself in court today," she told Ngamotu.
She said his motivation appeared to have been to intimidate and frighten, not harm, his sister.
