Former New Zealand under-20 international Blade Thomson has agreed to join Scarlets for the 2018-19 season.
Thomson, 27, has made 37 Super Rugby appearances for the Hurricanes since making his debut in 2013, and has won four caps for the Maori All Blacks.
"Blade's Super Rugby experience will a welcome addition to the pack and the squad as a whole," Scarlets head coach Wayne Pivac said. "He is a very athletic, no-nonsense player with a big engine who will be an effective ball carrier both in the wide channels as well as in the middle of the park.
"Blade is highly regarded in New Zealand whilst an untimely injury impacted on his rugby in the last six months but he's certainly a physical player who possess the skillset to play the Scarlets way."
Shoulder reconstruction surgery restricted Thomson to just two Hurricanes appearances in 2017, but he returned to Super Rugby action last weekend as the Wellington-based club were beaten 21-19 by the Bulls in Pretoria.
Thomson said: "I'm excited to join such a world-renowned club but my focus is fully on finishing the current season on a high with the Hurricanes and hopefully lifting some silverware."
