The 29-year-old follows top try scorer Matt Banahan and scrum-half Mike Baxter in securing their futures at The Recreation Ground.

"It was an easy decision. They are a great bunch of blokes that I play with and we are playing some good rugby," said Maddock.

Maddock joined Bath in 2004 from New Zealand club Canterbury.

The club had confirmed on Monday that both Banahan and Baxter were extending their contracts.

Coach Steve Meehan wants to get players to commit after lock Steve Borthwick decided to leave at the end of the season.

Matt Stevens and Olly Barkley are very high on the agenda. They are having talks with the club Bath coach Steve Meehan

Meehan told BBC Radio Bristol: "The recruitment of players has gone into overdrive after the interest Steve's departure caused."

Baxter returned to Bath this season while Banahan has been a revelation since converting from lock to wing.

The 6ft 7in winger has gone over eight times for Bath this season and has been tipped for a big future.

Meehan added: "Obviously Matt Stevens and Olly Barkley are very high on the agenda. They are having talks with the club, which is good news."
