A jury has found a teen guilty of murdering a teenage boy in a knife attack, although the defence argued he should be found guilty of manslaughter.

The High Court trial lasted a fortnight. The jury returned its unanimous verdict on Tuesday afternoon after just two hours of deliberation. The teenager has name suppression.

The Crown said the teen joined an attack on the boy, pulled a knife and stabbed him in the chest and neck. One of several blows severed an artery, causing the boy’s death. The teen did not know him.

The Crown alleged the teen stabbed the boy again as he fled. The defence disputed that second phase of the attack and questioned the reliability of a Crown witness to it.

Summing up the case for the jury earlier Tuesday, Justice Karen Grau said the Crown argued the teen had chosen to stab the boy in a dangerous or vulnerable part of the body.

The defence acknowledged that the teen had stabbed the boy but argued he had no intention to kill and did not know his actions could cause death. His lawyers argued the verdict should be manslaughter rather than murder. The jury did not agree.

The teen will remain in custody until sentencing next month.

Analysis

Why This Matters

The case highlights the complex legal intersection of youth, intellectual disability, and criminal responsibility, and the limits of the insanity or diminished-capacity defence in New Zealand law.
The attack, which involved Mongrel Mob affiliates and neo-Nazi chants, underscores ongoing concerns about gang violence and youth radicalisation in provincial New Zealand.
Kaea Karauria's death and the trial have drawn attention to the vulnerability of young people in gang-associated communities, and to the adequacy of support for those with fetal alcohol spectrum disorder.

Background

Kaea Karauria, 15, was stabbed to death in the early hours of May 11, 2025, on a street in Onekawa, a suburb of Napier, after a confrontation outside a party. The attack involved several individuals associated with the Mongrel Mob gang, and witnesses reported hearing the Nazi salute "sieg heil" shouted during the assault. The defendant, who was 15 at the time of the killing, was tried in the High Court at Palmerston North. Two other people have pleaded guilty to manslaughter in connection with the same attack, and two more faced charges of injuring with intent in the Youth Court.

Key Perspectives

Crown: The teenager intended to kill, or at least knew his actions could kill, and therefore is guilty of murder. Justice Grau, summarising the Crown case, said the defendant "chose to stab Kaea in a dangerous or vulnerable part of the body." After the attack, the teen recorded a video of his bloody hand holding the knife, which the Crown presented as evidence of his intent.

Defence: The teen had no intention to kill; his significant intellectual impairment, combined with the effects of drugs and alcohol, meant he could not appreciate that death was likely. The defence argued for a manslaughter verdict, saying the evidence only showed one stabbing on Dinwiddie Avenue, not the second phase claimed by the Crown.

What to Watch

The sentencing of the teenager, scheduled for next month in Napier, will clarify whether the court treats his youth and intellectual disability as mitigating factors or as aggravating in the context of gang violence.
The outcome of the related Youth Court proceedings against two others charged with injuring with intent will add to the legal resolution of the attack.
Any public or political response to the case, particularly around the role of gangs and neo-Nazi symbolism in the attack, could influence law enforcement priorities in Hawke's Bay.
