Jacob Duffy's four-for helped New Zealand wrap up a 3-1 T20I series win over West Indies with an eight-wicket victory on Thursday.

West Indies struggled to find their rhythm as they were bowled out for 140, with the Black Caps getting the chase over the line with 26 balls to spare.

It was a torrid start for the tourists, as Alick Athanaze (one), Shai Hope (11), Ackeem Auguste (eight) and Sherfane Rutherford (0) all skittled out by the end of the third over, with Duffy (4-35) taking the latter three in the space of five balls.

Roston Chase top-scored with 38 but tried to anchor the innings in vain as he was caught to drop the Windies to 90-6.

Romario Shepherd's 36 helped push West Indies forward before being stopped by Duffy, and James Neesham (2-31) dismissed Jayden Seales for a duck in the 19th over to set the target at 141.

Tim Robinson (45) and Devon Conway (47 not out) put on a 69-run first-wicket partnership before Shepherd sent stumps flying to finish the former's stand.

Rachin Ravindra and Mark Chapman, on his 100th T20I appearance, got 21 runs apiece, but it was Conway who got the all-important run to claim a 10th straight win in Dunedin for New Zealand.

Data Debrief: Duffy hits new landmark

Duffy impressed at University Oval, especially with his ruthless third over display, but also made a bit of history in the process.

His first wicket of the day was his 50th in T20Is, and he became the third-fastest New Zealand bowler to reach the landmark, doing so in 38 matches. Only Trent Boult (36) and Lockie Ferguson (37) got there quicker.

And Conway also surpassed 1,000 runs on home soil in the shortest format with his knock of 47; he has 1,013 in total after his measured performance.
