New Zealand captain Brendon McCullum admitted his first Test as captain was one to forget after they were crushed by an innings by South Africa in Cape Town.
The hosts won the match inside three days, bowling the Kiwis out for 275 in the second session to win by an innings and 27 runs.
New Zealand never recovered from being skittled out for 45 on the opening morning, and the only positive for the tourists was a maiden Test century for Dean Brownlie, who scored a stubborn 109.
McCullum said: "To lose a Test match inside three days hurts immensely.
"There's a very disappointed bunch of lads in the change room. I said it after day one and that hasn't changed. South Africa bowled exceptionally well and we weren't up for the challenge. We were outplayed.
"We've got to glean some positives from the performance. We know we haven't measured up."
South Africa captain Graeme Smith could not have been happier with his team.
"I don't think anyone can question our intensity in this game," he said. "It's a terrific start to the year.
"Obviously we would love to build on the momentum we created in 2012.
"We're a mature team now. I almost see us as a manly team. We've grown up now. We've come through a lot together."
South Africa's bowling hero Vernon Philander - who took the remarkable figures of 5-7 in New Zealand's first innings, is a doubt for the second Test in Port Elizabeth because of a hamstring injury.
