Police wouldn't have even known Phillip Awa-Tea Tapa had assaulted another Masterton man had he not made a complaint about the man who had "brutally" assaulted him.
Before Judge Barbara Morris recently, Tapa pleaded guilty to possession of an offensive weapon, namely a length of four by four timber.
Police had previously reduced the charge from assault with a weapon to the lesser charge.
Prosecutor Sergeant Garry Wilson said the victim had "come off worse" when Tapa went to the victim demanding money he was owed.
Tapa was hospitalised with broken ribs and then made a complaint to police about being assaulted.
