The 28-year-old is yet to rule out re-signing with the Cowboys, but has revealed he is in discussions with “a few people” in rugby.
The New Zealand international’s priority is finishing the NRL season “with a bang”, but is considering make the switch to his boyhood code of rugby union.
Kahu began his rugby career as a junior in his hometown, Lower Hutt, before moving to Australia and playing rugby league for Keebra Park State High in the Gold Coast.
When asked if he was keen to stay at the Cowboys, Kahu said: “Yeah, but we will see what happens.
“I have been a rugby union boy since I was young. That has always been an option. I have always wanted to go and have a crack at that.
“If that doesn’t come then I will have to play park rugby or something.”
When asked if he had made a decision on staying in the the NRL or moving to rugby next year, Kahu said: “Not really. I wish it has been locked in [by now].
“There have been talks with a few people but I can’t reveal who.”
In the short-term, Kahu is hoping to make a successful return from injury this week.
Kahu has been cleared to play for the Cowboys in their clash with Newcastle on Saturday after successfully recovering from a broken eye socket.
It was the latest in a long run of injuries for the winger, who has suffered a broken jaw and three knee reconstructions since his NRL debut in 2013.
“That’s the story of my career. I finally get a bit of confidence back and then something sets me back,” said Kahu, who spent six seasons at Brisbane before arriving at the Cowboys this season.
“But it has built my character and the person I am today. Although I have had numerous setbacks I think my body is in a good position where I can still play at the top level and I feel like I can still add to the team.
“I am trying to build that confidence again now and hopefully finish the year off with a bang.”
The former Bronco will line up on the wing against Newcastle, his first game since suffering the accidental elbow to the eye against the Sydney Roosters in round 17.
