The Blues have secured injury cover for second row Culum Retallick following the signing of Maori All Black lock Hayden Triggs.
Triggs, 31, heads to Auckland from Japan where he is currently based with the Honda Heat.
The 6 ft 7 in second row has previously turned out in Super Rugby for the Hurricanes, Highlanders and Chiefs, with 36 of his 40 appearances coming for the Otago-based franchise.
Triggs also spent six years playing for Manuwatu, making 70 appearances, ahead of stints with Otago and Waikato before moving north.
He will link up with the Blues following the conclusion of the Japanese season.
Retallick has been ruled out of the entire Super Rugby campaign after he ruptured his ACL in December.
