Rewi chased one of the associates of the Tribesmen gang during the confrontation. Three of his associates were convicted of murder and manslaughter and are still to be sentenced. The Crown accepted Rewi was not part of the group who assaulted Mr Lewis.
Justice Lang told Rewi he had a misguided sense of allegiance to the Mongrel Mob and felt the need to protect them. "You appreciate that your loyalty was misplaced."
Justice Lang said Rewi showed real promise but it was crucial he severed ties with the Mongrel Mob in Murupara.
"If you do not, your future is bleak."
Justice Lang said home detention was appropriate and sentenced Rewi to six months and two weeks' home detention which will be served at a Galatea address. He has also been sentenced to 180 hours' community work.
Justice Lang ordered Rewi not to live in Murupara for a year after completing home detention. Rewi was also told he was not allowed to work in the village during that time unless permitted to by a probation officer.
