(Reuters) - Coach Ian Foster wants his All Blacks to focus on claiming their own grand slam next weekend when they face South Africa looking for a clean sweep in The Rugby Championship after handing the world champions a narrow loss on Saturday.

Jordie Barrett's late penalty earned Foster's side a 19-17 victory over the Springboks that ensured the New Zealanders reclaimed The Rugby Championship trophy with a fifth win in a row in the southern hemisphere competition.
