The Auckland halfback Taniela Moa will join the All Blacks squad in South Africa as a replacement for Andy Ellis, who has aggravated his rib injury.
Moa is set to play for Auckland in this weekend's round of the Air New Zealand Cup before flying to Cape Town next week.
Halfbacks Jimmy Cowan and Piri Weepu are already part of the All Blacks 26-man travelling squad.
Ellis's ribs, first injured during the Tri-Nations Test in Sydney two weeks ago, were aggravated in training this week.
The 10-Test All Black was ruled out of selection after medical assessment when the team assembled last night.
