Luke McDonald is due to come out of contract at the end of this year and looms as one of North's priority re-signings along with Ben Jacobs and Shaun Atley.

The son of 155-game North forward Donald McDonald says he has opened talks with the club and does not foresee any major stumbling blocks.

"I think we've just started talking around now, so (there's) nothing really to worry about. I think that will get done sooner rather than later," he says.

McDonald says his contract status has not been a distraction and his strong start to the season bears testament to this.

The Kangaroos' No.11 has averaged 19.3 possessions a game over the first 10 rounds and is ranked third at the club for inside 50s (35) and equal fourth for goal assists (five).

He trained with North's midfield group over the pre-season, having split his time between defence and on-ball roles in 2017, but the return of tagger Ben Jacobs from injury and Jed Anderson's emergence as an inside midfielder has meant he's played predominantly as a defender.

Although he still has designs on a move into the midfield at some stage, McDonald is relishing being part of a tightknit backline that has helped make North 2018's stingiest team, conceding just 69.8 points a game.

"I absolutely love being in that team within the team down there, I really enjoy it," he says.

"As long as we're winning, I don't really care where I'm playing as long as I'm in the 22.

"Ultimately, I would love to play in the midfield, but I think one of my biggest strengths is being able to play wherever.

"So if that's in the backline, if that's best for the team, I'm happy to go there.”
