New Zealand 94 for 5 (Green 49*, Matthews 4-12) beat West Indies 93 for 9 (Jonas 3-16) by five wickets
However, the chase was steadied by Green and Lauren Down as the pair added 38 for the fifth wicket then Hayley Jensen accompanied Green the rest of the way as victory came with eight balls to spare. Green hit all six fours in New Zealand's chase with Plimmer also striking a six.
Matthews had dominated the early scoring during West Indies' innings as she made 30 of the 34 that came from the powerplay, but she skied to cover against the first ball after the fielding restrictions from Jonas.
Bates took her first international wickets in more than two years when she claimed Kyshona Knight and Cherry-Ann Fraser to finish with 2 for 5 from three overs. Although Amelia Kerr went at seven-an-over, between them New Zealand's spinners claimed 8 for 63 from 15 overs. In total, West Indies scored 59 in 14 overs after the powerplay.
