The Proteas now have an unassailable 2-0 lead in the three match series and could clinch a white wash against the seemingly struggling New Zealanders in their final match on Monday.
But it was Amla who stole the show on the day and his efforts were rewarded after he was crowned as the man of the match. Amla became the first batsman to score four ODI centuries in the current calendar year and became the fourth batsman after Kumar Sangakarra, Virat Kohli and Angelo Mathews to score 700 runs.
The New Zealand innings was a replication of the first match with five wickets falling before they had 70 runs on the board and the ninth wicket falling at 134. Once again the Proteas were frustrated by the last wicket partnership that eventually reached 76 between Luke Ronchi and Mitchell McClenaghan.
