The New Zealand cricket captain Brendon McCullum says Wednesday's win in South Africa will go down as one of the Black Caps' best-ever one day victories.
New Zealand's won the second one dayer in Kimberly by 27 runs, to take an unassailable two-nil lead in the three match series.
It's New Zealand's first ever one day series win in South Africa.
Batting first the Black Caps made 279 for eight, with Kane Williamson making 145 not out.
After being 167 for one, the Proteas then lost eight wickets for 65 runs to be all out for 252.
McCullum says he's not going to underplay the performance given they've had such tough tour, losing both test matches by an innings.
Game three, now effectively a dead rubber, is on Saturday.
