Rather than have him repeat courses he had already done, Sir Ron requested a psychologist's report to consider what more could be done, particularly to address Anderson's tendency to violence. Until that was considered, he said, the inmate remained an undue risk.
Anderson had been in a relationship with his victim for only a few months when the violence started, the court heard at sentencing.
In February 2018, the couple argued and the man head-butted her, knocking her unconscious.
After splashing water in the victim's face to revive her, Anderson continued the brutality.
He punched her in the face, chipping her tooth.
Weeks later, Anderson took his then partner's cellphone as he left the house and threw her on to a bed when she objected.
Pinning her down, he pulled her fingers back, tried to gouge her eye, elbowed her in the face, slammed his knee into her tail bone, pressed the pressure points behind her ears and forced a pillow against her face.
At sentencing, the victim read a powerful statement in which she said she thought she was going to die and had since been diagnosed with post-traumatic stress disorder.
The relationship finally ended when Anderson tried to strangle the victim and she bit him on the arm, resulting in him seeking hospital treatment.
At a later meeting, the court heard, the defendant accused her of seeing another man and threatened to kill both of them, before punching her in the face several times.
Anderson told the board he was committed to attending any violence-prevention counselling.
He will next come before the board in January.
His sentence expires in August 2023.
