Dale Steyn led South Africa to an emphatic victory over New Zealand in the second and final Test at Centurion.
Steyn helped himself to six wickets as the Black Caps were bowled out for 136 in their second innings, completing an innings and 59-run win for the hosts.
It was the South African paceman's second successive 10-wicket haul, while his second innings figures were a career-best 6-49.
Only former captain Stephen Fleming, who made 54, shone for New Zealand, who were outclassed throughout.
Steyn was named man-of-the-match when South Africa won the first Test in Johannesburg by 358 runs, and he was well on his way to the man-of-the-series award when he removed openers Lou Vincent and Michael Papps within nine balls on day three.
Both were out leg before but Vincent was unlucky as replays showed the ball would have missed leg stump.
Vincent was opening the batting in the place of the injured Craig Cumming, who had been struck by a bouncer from Steyn in the first innings.
Fleming and Scott Styris briefly threatened to hold up the Proteas' victory charge with a partnership of 60 for the third wicket, before New Zealand suffered another double blow.
Styris (29) was caught at second slip off Jacques Kallis and he was quickly followed back to the pavilion by Ross Taylor, who was run out by a smart piece of fielding by Hashim Amla at short leg.
Fleming reached New Zealand's first half-century of the series in the last over before tea, but he failed to add to his interval score of 54 before being trapped leg before by an in-swinger from Steyn.
New Zealand's weak resistance then crumbled as they lost their last five wickets for 19 runs, four of them to Steyn.
He completed the rout with a perfect full-length away-swinger which knocked Iain O'Brien's middle stump out of the ground.
Steyn's match figures of 10-91 were a slight improvement on his figures for the opening Test, when he collected 10-93.
Earlier Amla had completed his second successive century, while New Zealand fast bowler Mark Gillespie collected five wickets on his Test debut.
However, Gillespie's efforts could not prevent South Africa from taking a 195-run first innings lead.
South Africa lost five wickets for 60 runs at the start of the day, but a ninth wicket stand of 51 between Andre Nel and Steyn helped them to reach 383.
