Poite, who made the controversial call late in the drawn third Test against the Lions, will be a touch judge for the Cape Town match.
However, he won't referee for any New Zealand fixture, instead controlling the opening-round Springboks-Pumas Test in Port Elizabeth.
Five of the All Blacks' seven looming Tests will be officiated by Northern Hemisphere whistlers.
They get England's Wayne Barnes twice, including for the third Bledisloe Cup Test.
New Zealand referees Glen Jackson and Ben O'Keeffe have been handed a Test each in the Rugby Championship.
