The club announced on Thursday that they had signed the four-test All Black to a two-year deal, beginning in the French 2017/18 season.
Elliot joins a number of Chiefs heading overseas after this season, with halfback Tawera Kerr-Barlow (Toulon), first five-eighth Aaron Cruden (Montpellier) and wing James Lowe (Leinster) also taking their talents abroad.
The 31-year-old has been the Chiefs' starting hooker this season, however, with Nathan Harris' return not far off he might find himself moving to a bench role.
