About eight family members and supporters were in court for the appearance.
Crown prosecutor Matthew Temm successfully sought suppression of the victim’s name and any identifying features until a plea was entered.
Defence lawyer Jessica Tarrant confirmed her client wouldn’t be making a bail application but was seeking name suppression.
Judge Stephen Clark made interim suppression orders for both the defendant and victim.
He remanded the accused man in custody to reappear in the High Court at Hamilton on September 1.

The judge also ordered the preparation of mental health reports assessing the man’s fitness to plead.
In a statement this morning announcing the arrest, Detective Senior Sergeant Reece Durston said: “Police will continue to maintain a visible presence in the area in the coming days as a scene examination concludes.”
Police said they believed the incident involved “people known to one another” and no one else was being sought.
“Police believe there is no risk to the public following this incident.”
A Herald reporter at the scene this morning said a cordon had been erected across two properties.
About six police vehicles were parked on the street as well as a forensic police trailer.
Neighbours told the Herald they did not see or hear anything unusual yesterday and did not know the victim.
They first realised something had happened when they noticed police descend on the street yesterday afternoon.

Police had spoken to neighbours and asked if they had any information about what had occurred.

In a statement yesterday, Durston said a scene investigation was underway after a sudden death in the northern Hamilton suburb.
“The death is being treated as unexplained,” he said yesterday.
A cordon had been established and police would have a “visible presence” in the coming days.
Anyone with information about the incident was asked to call the 105 non-emergency line, referencing Operation Hatherly or file number 260819/2161.
