Edmund tweeted on Saturday afternoon that the veteran had chosen to walk from his home of 12-seasons and straight into Richmond's back-six, as is his right as an unrestricted free-agent.
Robbie Tarrant has told North Melbourne he is leaving as an unrestricted free agent. Set to join Richmond. Despite the Roos upping offer from one year to two he has decided he wants to join Richmond, who were considering Daniel Talia. More coming on https://t.co/5hhj3jzPVZ

The move allows both the Tigers to sure up a key defensive slot following the retirement of David Astbury and also see the 32-year-old offered a chance to vie for a premiership medallion as early as next season.
Tarrant was said to be weighing up his options with the club that drafted him at pick 15 in the 2007 draft, but has opted to depart as he was reportedly underwhelmed by the terms of the extension.
According to Edmund, Tarrant had initially bulked at the Roos' opening offer of a one-year deal, but upon understanding they risked losing his services, a second-year was sad to have been tacked on to the end of the proposed extension.
The 174-game Kangaroo will now walk freely to Richmond once the free-agency period commences on October 1.
The Mildura-born Tarrant managed to return to the playing field for 10-appearances this season following a kidney injury that required surgery.
Despite the Shinboners finishing at the foot of the table in 2021 and still requiring senior talent to aid the club's rise back up the ladder, club captain Jack Ziebell also remains uncontracted at the corner of Arden and Fogarty Streets.
The skipper is said to have been offered a one-year deal by the Roos, but is yet to have put pen to paper.
