New Zealand Women 208 for 8 (Dodd 52, Satterthwaite 42, Curtis 42) beat South Africa Women 113 (du Preez 62, Bates 3-17) by 95 runs
A patient fifty from opener Natalie Dodd and handy middle-order contributions from Amy Satterthwaite (42), Katie Perkins (34) and Sam Curtis helped New Zealand Women recover from 10 for 3 to post 208, a score they defended by 95 runs to take an unassailable 4-1 lead in the series.
South Africa's opening bowlers - Ayabonga Khaka and Marizanne Kapp, who bowled seven maidens in 18 overs between them - scythed through the top order, before an 84-run fourth-wicket stand between Satterthwaite and Dodd resuscitated the visitors. Dodd struck her maiden ODI fifty, a 107-ball 52, before she was stumped off Dane van Niekerk in the 32nd over.
Despite a lack of support from the lower order, Curtis provided the impetus towards the end of the innings with 42 off 53 as New Zealand added 42 off the last five overs.
Chasing 209, South Africa were left reeling at 28 for 4 by Lea Tahuhu and legspinner Erin Bermingham. Allrounder Marizanne Kapp retired hurt after she was struck on the head by a bouncer from Tahuhu and was treated for a mild concussion.
Mignon du Preez scored her second fifty of the series (62) in an innings that featured five fours and a six, but received little support from the other batsmen. Captain Suzie Bates claimed the last three wickets to fall as South Africa were bowled out for 113 in 35.5 overs.
