Originally contracted until 2022, the new deal will tie the inside midfielder to Alberton until the end of 2026 in a major coup for the club.
Wines, 26, has long been sought after by Victorian clubs, with several teams trying to lure him back to his home state in recent seasons.
However, Wines has now been locked away until he’s 32 years old, effectively making him a Port Adelaide player for life.
“The club is in a really strong position going forward and to be able to be a part of its long-term future is something I’m looking forward to,” he told the club website.
“I think we’ve built a powerful list that I’m excited about so I was only too happy to jump at the opportunity to be locked away to allow me to concentrate on doing what I need to do to put us in a position to chase our premiership goals.
“I’m so excited to be part of this young developing group and I can’t wait to see what we can do together.”
The former Pick 7 has played 158 AFL games for the Power since making his debut in 2013.
He averaged 21.8 disposals, 3.8 tackles and 4.8 clearances from 17 senior appearances in 2020 and played a key role in Port’s preliminary final run, getting named the best finals player.
