Port Adelaide coach Ken Hinkley has denied reports he has reached a new three-year deal with the club, but insists he will remain with the Power at least until the end of next season.

There has been growing speculation that Hinkley, who has a year to run on his contract, was preparing to jump ship to take up the vacant coaching role at the Gold Coast Suns.

That speculation was followed by other reports claiming Hinkley and the Power had reached a three-year deal that would ensure his future at the Power until the end of 2021.

But Hinkley this afternoon told radio station FIVEaa that while he was hopeful of securing a contract extension, no deal had currently been reached.

"I am contracted, and happily contracted, to be at Port Adelaide for season 2018, which means I'll be there," he said.

"The facts are, there has been some interest in me from outside of Port Adelaide. Clearly there's some reasons for me to think about those types of things.

"The Gold Coast has made some inquiries about my availability through my manager."

But Hinkley said his preferred future was with the Power.

"I'm really, really hopeful that something will happen quickly. I've great belief in [chairman] David [Koch] and [CEO] Keith [Thomas]," he said.

"Most definitely will I be coaching Port Adelaide in 2018 and I'm very, very hopeful that it's a lot longer to go."

Hinkley insisted his relationship with Mr Koch remained strong, despite the chairman's controversial spray to Power players in the wake of their heartbreaking, after-the-siren elimination final defeat to West Coast.

"Some of David's comments perhaps came out not exactly the way David would like. David and I have had that conversation," he said.

"He's given me everything I could possibly ask for for me to be a success as a coach. If he's made a little slip here and there occasionally, I'll live with that."

Despite a disappointing past few seasons, Hinkley has retained the faith of many Power fans.

He reversed the club's fortunes after taking the helm at the end of the 2012 season, and got the club to within three points of a grand final berth in 2014.
