The West Indies tamely surrendered their three match T20 series to New Zealand after suffering a 90 run defeat in Friday's second encounter at Sabina Park to trail 2-0.
The regional team chasing 216 for victory, laboured to 125-9. Last man Obed McCoy was the top scorer with 23 not out, while Jamaican Rovman Powell made 21.
Romario Shepherd 18, was the next best contributor against spinners Mitchell Santner and Michael Bracewell 3-15 apiece.
Earlier, former Jamaica Tallawahs representative Glen Phillips hammered 76 from 41 balls with six sixes and four fours to carry New Zealand to an imposing 215-5.
Phillips shared in an 83 run fourth wicket stand with Daryl Mitchell who made 48 from 20 balls.
Opener Devon Conway chipped in with 42 against McCoy 3-40. This was the Windies second heaviest defeat against the Kiwis in the format.
Captain Nicholas Pooran took responsibility for the team's poor batting display. New Zealand's captain Kane Williamson hailed a clinical performance which gives them a sixth straight win over the Windies in the format.
