New Zealand coach Graham Henry hailed the way his side bounced back from poor start to record their first win in South Africa since 2003.
Henry (R) was a happy man after the comfortable win
"It takes time to get used to the conditions," said Henry, after the All Blacks won 45-26 in Pretoria.
"For the first 10 minutes it looked like we were walking in porridge, but then they played very well, especially in attack in the second half.
"We were able to get the ball wide and score some great tries."
New Zealand, who sealed the Tri-Nations title last week, went behind early on but stormed to victory with an accomplished second-half display.
However, the victory was soured by injuries to Leon Macdonald and Greg Somerville, while number eight Chris Masoe and flanker Reuben Thorne are also doubts for next week's game against the Springboks in Rustenburg.
"Greg has torn his Achilles tendon, which has a huge recovery time of about six months and is very disappointing," added Henry.
"Chris (ankle) and Leon (hip) both have serious injuries, too, and will be out for at least two to three weeks. We think Reuben Thorne has broken his thumb."
South Africa coach Jake White said he was disappointed his team failed to build on their early lead.
"Apart from being concerned that we didn't capitalise on a good start, I'm also very concerned about the amount of space we gave them," he said.
"Obviously, conceding five tries means we have to look at our defence.
"If you make a mistake, the All Blacks will punish you and today they did that with 100% accuracy."
