All Black Sonny Bill Williams will play for the Chiefs in next year's Super 15 rugby competition.
The New Zealand Rugby Union has confirmed Williams has signed up with the national body for another year.
NZRU's general manager of professional rugby Neil Sorensen says they're delighted, as Williams is a special player who creates excitement and interest in the game.
The specific details of Williams's contract are confidential.
However, he retains the option of taking part in a limited number of professional boxing bouts.
