A prisoner was burnt so badly when boiling water was thrown on him by another inmate that his skin peeled away, a court has been told.
Aaron Forden is accused of injuring with intent to cause grievous bodily harm in the incident, which occurred in the high-risk prison wing at Paremoremo in August 2010.
His victim, Terry Jason Nahi, was also an inmate in the wing, nicknamed "D Block".
The crown says Forden stabbed Nahi in a planned attack which he and two other inmates co-ordinated.
Security cameras were covered before the scuffle, in which Nahi had boiling water poured on him and was stabbed in the head with a handmade shank.
In the Auckland District Court yesterday, Forden was handcuffed to a prison officer, while three more officers sat in the courtroom. A court security guard was also present.
Judge Grant Fraser told the jury not to read anything into the presence of the officers.
He said every prisoner coming into court was accompanied by officers and was handcuffed.
In opening, crown lawyer Scott McColgan said the attack on Nahi was all about "punishment and revenge".
Nahi was known as a trouble-maker and a bully, he said.
On the day of the attack, McColgan said Forden and two other prisoners - Jesse Ibell and Tamati Renata - waited outside Nahi's cell before Renata entered and threw the scalding hot water on Nahi.
Forden and Ibell then went into the cell where Forden stabbed Nahi above the eye with a home-made knife, or shank.
Nahi's skin was so badly burned it was peeling off his body, McColgan said.
Evidence will include CCTV footage of part of the event and photos.
Nahi was due to give evidence today from the remand centre in Christchurch, however, that was delayed until today after the video link failed.
A jury of nine women and three men will hear the case.
The trial is expected to last until the end of the week.
