An axe-wielding 28-year-old man who invaded a Bluff home and attacked two people, causing serious brain and other injuries, thought he'd killed them both.
Bluff meat worker Clayton William Dixon has admitted two charges of wounding with intent to cause grievous bodily harm and a third charge of burglary, while being armed with an axe.
Police prosecutor Sergeant Denise Harvey told Invercargill District Court on Tuesday that Dixon went to his former partner's home about 10:30pm on October 25.
Dixon struck the woman's new partner twice on the head with the axe, before the woman screamed at him to stop.
She rushed to her partner's side and put her arms over him, but Dixon struck her to the head with the axe an unknown number of times, Sgt Harvey said.
Sgt Harvey said Dixon admitted taking the axe from the garden shed, but he then blacked out and couldn't remember any further assault but agreed he was alone and had caused all of the injuries.
The next thing he remembered was standing over the woman who was lying injured on the floor and then leaving the house.
Dixon thought he had killed them both, Sgt Harvey said.
Dixon's ex-partner underwent lengthy surgery in Dunedin Hospital, but her long-term prognosis is uncertain, Fairfax reports.
She suffered a brain injury and could face long-term disabilities, Sgt Harvey said.
Judge John Macdonald remanded Dixon in custody until February 28 when he will be sentenced.
