Lachlan Burr has confirmed his move from Canterbury to New Zealand in an Instagram post on Friday.
The 26-year-old starred in the Dogs' reserve grade side last season, as was named as the team's best player, but the second rower failed to make an NRL appearance in 2018.
Burr moves to the Warriors after 24 NRL appearances overall, one with the Dogs in 2013 and 23 with the Titans over the 2015-16 seasons.
The forward also had a stint in England, playing with Leigh in the Super League.
The Warriors haven't officially confirmed the signing, although his signature is expected to be announced in the coming days.
