Batting first, the Black Caps have set the West Indies a target of 178 in the third Twenty20 of the five-match series - although they may feel they left a few runs out on Saxton Oval, after a late innings collapse.
Devon Conway topscored with a fluent 56 off 34 balls, before he was run out by a brilliant throw from the deep.
Daryl Mitchell blasted 41 from 24 deliveries, including a huge 80-metre hit for six.
New Zealand lost wickets cheaply late to end on 177/9, with Sharmar Springer bowling two tidy overs at the death.
