Ahmed was the star performer for the Junior Springboks when they won the Under-20 World Championship in Tbilisi last month and is handed a stiff test of his ability as the All Blacks begin their eight-match tour of South Africa.
The 20-year-old gets his chance because Sacha Feinburg-Mngomezulu is away with the Springboks, who play Argentina in Buenos Aires on Saturday, and Jurie Matthee is injured.
The loose-forward trio of Evan Roos, Hacjivah Dayimani and Deon Fourie is the same combination that started the United Rugby Championship final four years ago when the Stormers won the title.
Outside centre Ruhan Nel will captain the team.
