A shaven-headed man delivered a Nazi salute to a judge after receiving a first-strike warning for repeat violent offences.
He had punched two victims, stabbed one of them, and then tipped a fridge on top of them.
Jamie Richard Harris, 23, had pleaded guilty to charges of injuring a man with intent to cause grievous bodily harm and assaulting a woman with intent to injure.
He stood staunchly in the dock when he was not laughing along with supporters in the public gallery at Christchurch District Court.
He shrugged when Judge Alistair Garland began reading the first strike warning and then gave the Nazi salute as he was led out of court in custody for sentencing on August 9.
The judge asked for a pre-sentence report but no report on Harris' suitability for home detention.
Police prosecutor Sergeant Paul Scott said the incident happened about 11pm on May 1 when Harris went to his mother's address in Ferry Rd, Christchurch.
When he was introduced to a man at the address he punched him in the face, knocking him to the ground unconscious. As the victim lay on the floor, Harris punched him in the head several more times.
The woman who had introduced the victim to Harris tried to intervene and Harris punched her in the head about five times.
Harris then picked up a knife and stabbed the man twice in the back as he lay on the floor, leaving two wounds with one cut about two centimetres long.
He then pulled a fridge over on top of the two victims, raised his foot and stomped on the back of the fridge, further crushing the victims, Scott said.
Harris was pulled away by his father and left the address.
The man received extensive bruising to the face and body, a fractured eye socket, and the stab wounds.
The woman received bruising and swelling to her face and ribs.
Harris admitted the facts and told police he was "highly intoxicated and not in the right head space", Scott told the court.
