Hashim Amla made a superb 92 to lead South Africa to an emphatic ODI series-clinching six-wicket win over New Zealand in Napier on Wednesday.
Amla smacked 12 hours in his 107-ball knock and JP Duminy contributed a quickfire 43 as the Proteas overhauled a target of 231 with more than 11 overs to spare.
Earlier Morne Morkel had taken five wickets as New Zealand collapsed from 163-2 to 230 all out, despite 85 from Brendon McCullum and 58 from Martin Guptill.
Morkel finished with 5-38 and Lonwabo Tsotsobe 3-43 as the Black Caps lost 8-67 in 16 overs on a flat wicket.
The visitors, who went 2-0 up in the three-match series, never looked in danger of not reaching their target, despite the early loss of Jacques Kallis (four).
Guptill then produced a brilliant catch to dismiss Francois du Plessis (34), taking the ball on the boundary and then, with his momentum taking him over the rope, throwing it in the air and catching it again as he stepped back in play.
But that was as good as it got for the hosts as Amla and Duminy piled on the runs, taking the score to 167 before the latter was caught and bowled by Tarun Nethula.
Amla edged another Nethula delivery behind to McCullum to leave South Africa on 192-4 in the 32nd over, but AB de Villiers (31no) and Justin Ontong (17no) steered them home with plenty to spare.
Earlier, the Black Caps lost 3-20 in the batting powerplay and never recovered.
Having been put in to bat, New Zealand lost Rob Nicol early on, but manoeuvred themselves into an excellent position thanks to a second-wicket stand of 107 between Guptill and McCullum.
McCullum pulled Robin Petersen for six while Guptill moved calmly to 50, but the opener attempted to cut a ball that was not wide enough in Kallis' first over and was caught behind.
McCullum appeared to be building a similarly dangerous partnership with Kane Williamson, but the new man was well caught by Kallis running back off Tsotsobe three balls into the powerplay, sparking a collapse.
McCullum picked out Ontong at deep square leg and Jesse Ryder fell for a duck, before Morkel wrapped things up by taking the last five wickets, interrupted only by some lusty hitting from Tim Southee, who added 28 in 27 balls.
