There had been talk that one of the Power's most important players could be tempted to make a return to Victoria.

But the deal commits the 21-year-old midfielder to Alberton until at least the end of the 2018 season.

Wines is the fastest player to reach 50 games for Port Adelaide and his short career has already netted him three consecutive awards for best under-21 player at the club.

Wines, a member of the Port leadership group, said it was always his intention to re-sign before the start of the year as leaving the club was never an option.

"I love this footy club, my teammates, coaches, and our fans and I'm very happy to be continuing my career here at Port Adelaide," he said.

"Now just feels like the right time to re-commit to the club as I didn't want our members thinking I might leave this year, when that wasn't part of the plan."

Senior coach Ken Hinkley said the club was delighted with Wines' decision.

"Ollie is one of those players who you love having around your footy club," said Hinkley.

"His work ethic, his professionalism around the club and his compliance on the field are all qualities that he's built on over the last three years and he continues to want to improve.

"I know he has put a great deal of thought and reflection into this decision – that's his style – but we were always confident he would put pen to paper.

"He's the sort of young man who will live and breathe this footy club and his relationships with our players, coaches and supporters are very strong. It's great to have him on board until at least the end of 2018."
