Dwayne Smith and Chris Gayle combined to destroy the New Zealand attack as West Indies won the first one-day international at Sabina Park by nine wickets under the Duckworth/Lewis method.
The pair shared a stand of 130 as the hosts triumphed with 52 balls remaining, Gayle typically swashbuckling on his way to a score of 63 from just 57 deliveries including five sixes and four fours. Smith top-scored with 65 from 77 balls, plundering six boundaries and three sixes.
Andre Russell earlier finished with four for 45 as the Black Caps posted 190 for nine, with BJ Watling (60) and an ebullient 32 from Jacob Oram the highlights.
West Indies made a poor start to their reply with Lendl Simmons out for a duck, caught by Watling off Kyle Mills, but Gayle promptly set about the attack. He hit Tim Southee for six with a seemingly easy swing of the bat and took Oram for 10 in two deliveries, again apparently effortlessly.
Gayle was being ably assisted by Smith, who reached 1,000 ODI runs with another six off Oram that crossed the deep square-leg boundary. Three deliveries later and Gayle skipped down the wicket before dispatching the ball into the crowd. However, with a downpour due and lightning around, the covers came on with the score on 93 for one after just 18 overs.
When play resumed, the hosts required 43 from 15 overs and they continued where they left off, Gayle reaching his fifty with a single off Southee. Smith was not to be outdone, registering his half-century in style by launching Tarun Nethula for six over long-on.
He was dropped by Rob Nicol but the Windies' march was relentless, Smith hitting the winning runs as West Indies comfortably reached their victory target of 136. Earlier the hosts had won the toss and, with just the eighth ball, Martin Guptill became Russell's first victim when he got an outside edge to leave the visitors on three for one.
Nicol and Daniel Flynn put on 27 before Russell struck again, clean bowling the latter for 12 with the former out for 14 when he powered the ball to mid-wicket where Simmons awaited. Dean Brownlie had made only one when he was lbw to Sunil Narine.
Kane Williamson put on 23 with Watling before the debutant captain was out, feathering a Darren Sammy delivery through to Denesh Ramdin. His 24 was cautious, coming off 52 deliveries. Oram and Watling put on 46 before the former was bowled by Ravi Rampaul, his 32 coming off 39 deliveries and including two boundaries and two sixes.
Watling and Andrew Ellis enjoyed a stand of 44 before the latter became Narine's second victim when he was clean bowled for 14. Mills (one) became Russell's fourth victim and Watling finally fell with a little over two overs remaining when he was lbw to Rampaul. His 60 came off 98 deliveries including five boundaries.
