The Black Caps have produced a gritty performance with the bat to beat the West Indies by one wicket in the fourth ODI in Barbados and clinch the five-match series.
After trailing 1-nil early in the series, New Zealand have pulled off three straight low-scoring wins, with none of them closer than at Kensington Oval in Bridgetown.
After dismissing the hosts for 188 in the 45th over on a difficult batting surface, the Black Caps inched 189 for nine with 35 balls still to spare.
The run chase looked well in hand at 142-4 as Mark Chapman raced to 80 off 82 balls, adopting an aggressive approach and striking eight fours and four sixes.
His dismissal sparked a collapse and a nervous finish, as New Zealand scored 47 runs and lost five wickets over the last 14 overs of their innings.
A key figure was captain Mitchell Santner, who struck the winning runs and finished 34 not out.
He was fortunate to survive when New Zealand were three runs short of their target, lofting a miscue into the outfield off the bowling of seamer Jayden Seales.
The ball fell between two converging fielders and was dropped by Justin Greaves, leaving the West Indies players and a small crowd crestfallen.
No.11 batsman Jayden Lennox played out a maiden over bowled by Vitel Lawes, leaving Santner clear to hit the winning runs off Seales from the first ball of the 45th over.
“It was pretty chaotic, especially at the end,” player of the match Santner told the host broadcaster.
“We probably shouldn’t have let it get that close, but it was nice to get over the line.
“We were very happy to bowl them out for 188 but we know how good the West Indies bowlers are, and they were pretty good today.”
Earlier, paceman Matthew Fisher returned the best Black Caps bowling figures of three for 40 off eight overs.
The New Zealand spinners were tight once again, with Santner and Michael Bracewell bagging two wickets each.
West Indies tweaker Gudakesh Motie was highly effective during the chase, taking 5-47, including the key scalp of Chapman caught in the deep.
The dead rubber fifth match is a day-night affair at the same venue on Wednesday morning (NZT).
