New Zealand fell to their third lowest Test scored of 45 on the opening day of the two-match series against South Africa at Newlands.
Vernon Philander claimed five wickets for seven runs as the tourists were bowled out for a paltry return..
Hashim Amla then scored 66 as South Africa made 119 for two in reply to lead by 74 runs.
Philander ripped through the New Zealand order as South Africa began the two-Test series in the manner befitting the world's number one ranked side.
Philander grabbed five for seven runs as the tourists lived to regret their decision to bat first on the opening day at Newlands.
Only Kane Williamson reached double figures but his top score of 13 was typical of a New Zealand batting display which crumbled in just 19.2 overs.
Philander struck in the second over as he claimed a wicket maiden, Martin Guptill's outside edged being snapped up by AB de Villiers behind the stumps.
Guptill fell for just one in an over which cost seven runs after De Villiers had given away four overthrows from Philander's first ball.
The home crowd only had to wait four more overs before Philander struck twice, cleaning up Brendon McCullum (7) with a length ball which removed middle stump.
Three balls later Dean Brownlie (0) looped a catch to Graeme Smith at slip and the tourists were in trouble at 14 for three.
Dale Steyn's following over cost nine runs as Williamson at least showed a little resistance.
But Philander returned to remove him lbw for 13 as New Zealand finished the eighth over on 27 for four.
Philander and De Villiers combined to remove BJ Watling for a duck before Morne Morkel got in on the act to dismiss James Franklin, caught by Smith for one, to reduce the tourists to 28 for six.
When Doug Bracewell was bowled by Steyn for two, New Zealand were 31 for seven and looking at an embarrassing first innings total.
Jeetan Patel (5) was the next to go but was unlucky that his drive at Morkel went to the left of Amla at close mid-off and the South African dived low to his left to take the catch.
Travis Boult had contributed just one to the total when he was caught by De Villiers off Morkel and Steyn ended the rout when he caught and bowled Daniel Flynn for eight as the tourists capitulated for 45.
Philander was the star of the show with seven for five, including three maidens from his six overs, but Morkel's three for 14 and Steyn's two for 18 were also impressive figures.
In the two remaining overs before lunch South Africa lost captain Smith when he was trapped lbw by Bracewell to leave the home side's reply on three for one.
But Amla and Alviro Petersen put on a century before the second wicket fell as the tourists were made to work hard in the field.
Amla had scored 66 when he played around a delivery from Franklin and fell lbw, leaving the home side on 108 for two.
Petersen (45) and Jaques Kallis (6) guided South Africa to 119 for two at tea and a lead of 74 runs.
