The defendant, who has interim name suppression, appeared in the High Court at Dunedin this morning after he was automatically transferred from the Youth Court due to the nature of the charge.
He pleaded not guilty to murdering Enere, 16, who died on May 23 after being rushed to hospital.
Following the Trinity Catholic College pupil’s death, principal Kate Nicholson said the school's hearts "go out to his whānau who are going through this terrible loss".
"It is so devastating, heartbreaking and sad to lose someone so young and full of energy and promise in such a senseless and horrific way," she said.
Enere’s funeral was held at First Church last week where King’s High School pupils led a haka in his memory.
The court heard it was possible a trial for the 13-year-old would not go ahead until 2026.
