The All Blacks have lost experienced prop Charlie Faumuina to France.
The Blues frontrower has agreed to join the Toulouse club for the next European season.
The 30-year-old has played 46 tests for the All Blacks and has played for the Blues since 2009.
He will still play for the Blues in next year's Super Rugby competition and is eligible for selection to play against the touring British and Irish Lions next June.
If selected, he would join Toulouse after the Lions series and in time for the French season.
