Nick Williams has agreed a contract extension with Ulster, keeping him at Ravenhill until 2016.
The New Zealand back row, who was voted the RaboDirect Pro12 players' player of the season last year as well as the Irish Rugby Union players' player of the year, was due to be a free agent at the end of the current campaign.
"It's always nice to stay where you're happy," Williams told the club's official website.
"My family and I have settled really well and it means I can go out and enjoy myself on the pitch. Everything has fallen into place and I wouldn't want to play anywhere else to be honest."
Ulster's director of rugby, David Humphreys, was delighted to tie down the influential 29-year-old.
"Nick's level of performance throughout last season was instrumental to Ulster finishing top of the RaboDirect PRO12 and extending his contract for another two years is a huge boost to everyone associated with Ulster Rugby.
"He is a genuine entertainer and is someone who possesses the ability to inspire the players around him and get the crowd on their feet. Off the field, he's a tremendous personality to have around the dressing room and I'm delighted he's committed to Ulster until 2016."
