Port Adelaide midfielder Willem Drew has signed a new long-term deal with the club to be locked in at Alberton until the end of 2028.

Drew's extension comes just days after fellow onballer Zak Butters inked a two-year deal, with the midfield pair both initially set to come off-contract in 2024.

The four-year extension is set to see the 25-year-old further add to his 81 games for the Power - 70 of which have come in a current uninterrupted run.

Drew has emerged as a key defensive cog in Ken Hinkley's engine room over the past three seasons and is now set to call South Australia home for the next five years.

“I'm thrilled to have signed on with Port Adelaide for the next five years,” Drew said in a club statement.

“It feels our entire club is building great momentum both on and off the field. We have an exciting young list, a really connected playing and coaching group and worldclass training facilities, so the decision to stay was easy from my perspective.

“I have no doubt our club is tracking in the right direction and I want to be part of it.

“It's good to extend the contract now so I can focus solely on a strong pre-season campaign ahead of 2024.”

Drew joined the Power out of Koroit, Victoria as the 33rd overall pick in the 2016 National Draft, with the 188cm onballer averaging 17.40 disposals and 6.15 tackles per game across his career.

Port Adelaide list manager Jason Cripps believes Power fans are yet to see the peak of Drew's powers as he prepared to enter his prime.

“Willem is a well-liked and highly respected member of our playing group for his work-rate and the care he shows for his teammates,” Cripps said.

“He is approaching 100 games now, having performed at a consistent level for three years, and we see him entering the prime of his career as a key part of our midfield.”

The re-signings of Drew and Butters leave Port Adelaide stars Connor Rozee, Todd Marshall and Allir Aliir as the club's key retention targets going forward.
