The young inmates of Ngāwhā prison's Kea Unit beat a team of police officers from around the Mid North in a first-to-three volleyball tournament on Friday.
It was a close contest, both sides winning two games apiece before the prisoners clinched the final and the coveted trophy, carved three years ago by Kea inmates.
After a shared meal the prisoners awarded certificates for everything from most improved player (stand up Kaeo's Constable Joe Wright) to best spikes and player of the day, and performed a rousing haka for their opponents.
Kea team captain Michael (not his real name) said the tournament was a "cool experience".
"The main objective was to get together, working with each other instead of against each other. It also gives us ties to Northland police when we get out, so we've got someone to talk to," he said.
