The New Zealand captain played a lone hand as the top-order fell collapsed around him, making exactly 100 before he was dismissed at 148 for six. A late flurry of runs from Kyle Mills (47 not out) lifted New Zealand to 231 for nine.
South Africa A paceman Johan van der Wath restricted the flow of runs as well as taking wickets, finishing with four for 31 from his 10 overs.
Davey Jacobs got the home sides chase off to a rapid start with six fours in his 26 off 20 balls. However, New Zealand medium pacers Nathan Astle and Andre Adams gave the batsmen little to hit, their combined 18 overs costing just 51 runs.
Fast bowler Shane Bond wrapped up the tail as he grabbed four wickets in 11 balls to finish with five for 37 in 5.5 overs as South Africa A slumped to a paltry 128 all out.Scores:
New Zealand: 231-9 (Stephen Fleming 100; Johan van der Wath four for 31) v South Africa A: 128 (Shane Bond 5-37).
