North Melbourne forward Aaron Black is set to leave the Kangaroos this season, with Fremantle, one of "a number of clubs" interested in the 25-year-old.

Black's manager, Jason Dover, told AFL Trade Radio on Wednesday that his client and the club have agreed to part ways, with Black starved of opportunities over the past few seasons.

"Fremantle probably had other targets, in my opinion, over the last month, and a couple of them might have come off the page yesterday," Dover said, referencing Jesse Hogan and Rory Lobb, who recently re-signed with their respective clubs in Melbourne and GWS.

"It's probably a conversation that we will revisit given they might also have (Chris) Mayne going out, and have lost (Matthew) Pavlich.

"We've had some positive conversation with a number of clubs."

Black has played 65 games for the Roos since making his debut in 2010, however, failed to play a senior game this season.
