Brett will now be at the Gnoll until at least the end of the 2004/2005 season.
Neath Director Mike Cuddy said: "Brett was keen to extended his contract for a further year.
"As a club we have to secure players of his quality on long-term contracts if we are going to build a team capable of performing in the European Cup, as well as performing in the Welsh Scottish league.
"Many sides in Wales and over the border have courted his services, and we are delighted that he is staying at the Gnoll as Brett is performing on top of his game and is clearly the best openside in Wales at the moment"
