The Hāwera-born forward represented New Zealand Secondary Schools, Canterbury Under-19, the New Zealand U20 side, and the Māori All Blacks, earning him All Blacks selection in 2020, playing his sole test against Australia in Brisbane.
Grace said he’s looking forward to embracing a new challenge in the Northern Hemisphere.
“Scarlets is a very proud rugby club with a great history and tradition and that was something that really appealed to me. It is a challenge I am really looking forward to and I can’t wait to get started.”
He joins a growing list of All Blacks departing Aotearoa, including fellow Crusaders Sevu Reece, Braydon Ennor and Dallas McLeod, as well as Blues trio Stephen Perofeta, Dalton Papali’i and Hoskins Sotutu.
