Faumuina, 30, is heading to French club Toulouse at the end of the season.
He earnt his 50th test cap in the drawn third test against the British and Irish Lions at the weekend and this weekend's match against the Japanese side the Sunwolves would have been his 100th Super rugby game had he not missed the match against the Queensland Reds in Samoa earlier this season due to tonsillitis.
Former All Black loose forward Steven Luatua will also play his last match for the Blues.
