Ponga is contracted for next year at Newcastle, but has a two-year option in his favour after that, technically allowing him to talk to other NRL teams about his future.
It has led to speculation that
Dolphins coach Wayne Bennett will look at Ponga as his first marquee signing, with the NRL's 17th team not joining the league until 2023.
During a press conference after returning for pre-season on Wednesday, Ponga was quizzed about his future and the potential move to Redcliffe - but the fullback brushed it aside and revealed he's had no discussions at this point.
"No thoughts or discussion there from me," he said.
"To be honest my nerves have been building for today since I got back from Burleigh. I've just been thinking about today and am excited about building on last year.
"It's not using any of my energy for them to talk. My energy is here, my focus is here, my attention is here.
"I want to be better this year and I get to have a pre-season which I'm very excited about."
Newcastle have made the finals for the past two years, but have fallen out in the first week to both South Sydney and Parramatta.
Ponga is one of the game's most exciting players, and would be a fantastic acquisition for a start-up franchise like The Dolphins, who will be keen to make a mark from the moment they enter the competition.
The four-time QLD Origin representative said the idea of working under a legendary mentor in Bennett hadn't crossed his mind, and is fully-focused on premiership glory at the Knights.
"No I haven't (spoken to Bennett)...I've seen a couple of articles, I don't like to read that sort of stuff," he said.
"The carrot dangling is a premiership at the end of this year. I'm excited to win that I want to get after that. That's the carrot for me and it has been the last year, the year before.
"I just want to build on the back of last year and be better, more connected as a team. I'm excited for that."
