Former Highlanders captain Nasi Manu, who's now based at Italian side Treviso, adds depth to the loose forwards.
Narbonne prop David Feao - the son of former Tonga international Willie Feao - earns his first call-up, having previously represented Tonga Under 20s and Tonga A.
He's one of three new caps in the front row, alongside former Waratahs loosehead David Lolohea and ex Australian Schoolboys and Under 20s prop Vunipola Fifita.
