Port Elizabeth: South Africa completed a 2-0 series win over New Zealand on Monday after thumping the visitors by an innings and 193 runs on the fourth day of the second Test.
Fast bowler Dale Steyn claimed innings figures of three for 48 and match figures of eight for 65, as New Zealand were bowled out for 211 in their second innings, half an hour before lunch.
New Zealand also lost the first Test by an innings after they were bowled out for 45 before lunch on the opening day.
South Africa captain Graeme Smith said that he had been pleased by the standard of cricket his team had played over the series as they strengthened their position as the world's top-ranked Test nation.
"We've had to work hard to get into this position and it's nice to keep playing well… It's been a wonderful two Test matches for us," Smith said at the post-match presentation.
"They (the wins) were very professional and both were very big wins. A lot of the guys contributed and I thought our style of cricket, and the way we played, was good. Barring a couple of dropped catches in the first Test, I thought our cricket was of a very high standard.
Dean Brownlie and BJ Watling provided the bulk of New Zealand's runs with a 98-run fifth wicket partnership.
Brownlie brought up his fourth Test fifty but after making his way to 53 off 141 balls, he edged a delivery from Jacques Kallis to 'keeper AB de Villiers.
