Coach Heyneke Meyer says the Springboks will need to go up a gear when they face the All Blacks in a top-of-the-table Rugby Championship clash in Auckland on Saturday.
South Africa will field the same starting 15 and the same bench as they did for their 38-12 humbling of Australia in Brisbane last weekend.
Meyer says it's a great position to be in to be able to name an unchanged squad, but adds that he has utmost respect for the All Blacks.
"You don't want to get into the situation where it's easy to pick the same side and everything goes well and you've won," he said.
"We know we have to make an unbelievable step up. This is the best team in the world we're facing."
Meyer said some of his players had the flu but he expected they would all be over it by match day.
Both South Africa and defending champions New Zealand have won their first three matches of the tournament, but the Springboks lead the table because they have an extra bonus point.
New Zealand will name their team on Thursday morning.
South Africa: Zane Kirchner, Willie le Roux, JJ Engelbrecht, Jean de Villiers (captain), Bryan Habana, Morne Steyn, Ruan Pienaar, Duane Vermeulen, Willem Alberts, Francois Louw, Flip van der Merwe, Eben Etzebeth, Jannie du Plessis, Bismarck du Plessis, Tendai Mtawarira.
Reserves: Adriaan Strauss, Gurthro Steenkamp, Coenie Oosthuizen, Juandre Kruger, Siya Kolisi, Jano Vermaak, Pat Lambie, Jan Serfontein.
