Prison director Andy Langley says a makeshift weapon - which RNZ understands was a shank - was used in yesterday's attack.
Mr Langley has confirmed that a prisoner had to be hospitalised after the attack.
He also confirmed it was gang-related, but quickly brought under control by staff.
Mr Langley said police were investigating.
RNZ News understands there was a brief stand-off with the prisoner and authorities carried out cell searches, looking for other weapons, after the attack.
