A brother and sister have been sentenced to prison terms after they performed a brutal home invasion with their mother.
Horeta and Hinemoa Epere were sentenced in the High Court at Auckland this morning by Justice Murray Gilbert.
Hinemoa Epere, 21, was sentenced to one year and 11 months for two counts of burglary.
Horeta Epere, 23, received seven years, two months for burglary and causing grievous bodily harm with intent to cause grievous bodily harm.
Their mother, Jane Albert, was previously sentenced to seven years, eight months in prison.
Justice Gilbert said the family was drinking on the night of 28 October, 2012, before they went to find a former flatmate of Albert's.
"Ms Albert was the instigator, she enlisted the help of her son and daughter," the judge said
Hinemoa Epere and her mother went to the flatmate's mother's house, forced their way in and yelled and swore, demanding to know where the woman was.
They went to another house and on the way the trio talked about "smashing" the woman when they found her.
The woman, her partner, 10-year-old daughter and a boarder, barricaded the front door with a sofa as they had been warned by the woman's mother.
Albert and the Eperes smashed down the glass front door and entered the house.
The family had locked themselves in the boarder's room but Horeta Epere smashed down the bedroom door with a baseball bat.
Horeta hit the woman several times with the bat then gave it to his mother who continued the assault on the woman who was cowering on the floor.
She received a broken elbow, broken knee, a laceration to her head and severe bruising all over her body.
The woman spent three days in hospital, the judge said.
Epere's lawyer Vicki Pomeroy said her client's contribution was less than his mother's - "only four hits".
Hinemoa Epere said she left the house before the violence started; the charge of grievous bodily harm she faced was withdrawn.
