Anderson played 99 games across his career, 89 of those with North after beginning his career at Hawthorn. The 28-year-old played 14 in 2022, averaging 22 disposals and 4.1 tackles per game.
Bosenavulagi played 17 games for the Kangaroos during his two years on the list, making the move from Collingwood at the conclusion of the 2020 season.
26-year-old Turner departs the club after nine seasons and 118 matches. The 2014 rookie draft selection has formed part of the Kangaroos' leadership group for the last two seasons.
Walker played 54 games in royal blue and white since joining the club ahead of the 2020 season, having spent time across his 12 year career at Geelong and North Melbourne. The 29-year-old defender departs the club with 139 senior games to his name.
North Melbourne's list and recruiting manager Brady Rawlings thanked the quartet for their time at Arden Street, revealing that the club may consider re-drafting one or two of the delisted players on rookie contracts.
“List management decisions are never easy, but they must be made in the best interests of our club,” Rawlings said.
“We require four primary list spots for the upcoming AFL national draft which means we have had to make some difficult decisions.
“In saying that, given the strength of character of the players delisted, there is potential for one or two of these guys to be considered for a spot on our rookie list in 2023.
“Jed, Atu, Kayne and Josh all made significant contributions to our football club over a number of years. We wish them well for the future, they will always be welcome at North Melbourne.”
