Springboks Coach Rassie Erasmus says the All Blacks will be a "step up" in the competition after they swept past Australia to kick-start their Rugby Championship campaign in style.
The two-time reigning world champions scored the game's only four tries in their 30-12 victory in front of 58,197 fans at Perth's Optus Stadium last Saturday.
South Africa made 10 changes after a 33-7 triumph last week in Brisbane, but their depth of talent and firepower off the bench crushed a gritty Wallabies in wet conditions.
Erasmus says they have always struggled against Australia and are always pleased with a win.
The Springboks will host two Tests against a rejuvenated All Blacks, starting with a clash in Johannesburg next Sunday.
It will be the first time the powerhouses meet since last year's tense World Cup final when South Africa defended their title with a 12-11 victory.
Erasmus says they saw how New Zealand turned things around after last week's result, so they know the challenge that awaits them, and it will certainly require another step up.
South Africa will host the All Blacks at 3am next Sunday, and Argentina will face the Wallabies at 10am next Sunday.
