West Indies 293-9 (C H Gayle 135, S Chanderpaul 94, M R Gillespie 4-58) v New Zealand 211-5
New Zealand beat West Indies by 9 runs (D/L Method)
New Zealand clinched a 2-1 one-day series victory over West Indies with a nine-run Duckworth/Lewis success in the final match.
Opening batsman Chris Gayle smashed 135 to lead the tourists to 293-9 after being asked to bat at Napier's McLean Park.
Gayle was well supported by Shivnarine Chanderpaul in a third-wicket partnership of 170.
New Zealand's run chase was characterised by solid contributions from the top five, led by Brendon McCullum's 41 off 28 balls, although they also lost regular wickets.
The hosts had reached 211-5 in 35 overs, with Ross Taylor unbeaten on 48, when the rain arrived to bring a premature halt to proceedings.
Black Caps skipper Daniel Vettori opted to bowl first after winning the toss and it looked a good decision when Kyle Mills struck in the third over to remove Sewnarine Chattergoon (1).
Gayle and Ramnaresh Sarwan added 72 runs before Sarwan (22) top-edged Mark Gillespie to fine-leg to leave the West Indies 73-2.
But that brought Chanderpaul to the crease and he and Gayle set about rebuilding the innings. The pair cut loose when they called for the third powerplay, taking 57 runs off those five overs.
Gayle equalled Brian Lara's total of 19 one-day hundreds when he took a single off Grant Elliott's medium pace in the 37th over.
The left-hander also became the fourth West Indian to score 7,000 one-day runs, bringing up that milestone in a Gillespie over that also saw him hit a huge six out of the ground and into someone's backyard.
But a late collapse saw West Indies slip from 243-3, when Gayle was caught by Taylor off Mills, to a final total of 293-9.
By the time Chanderpaul was dismissed in the 47th over, caught from a miscued reverse sweep, he had powered his way to 94 off 91 balls and hit a total of nine fours and a huge reverse sweep for six.
But his departure prevented a 300-plus total being amassed as three wickets fell in the last two overs. Gillespie finished with figures of 4-58 and Mills 3-57.
New Zealand got off to the perfect start with Jesse Ryder - back after his one-match suspension - and McCullum on the front foot early as they smashed their way to 59 runs in under six overs.
But having walloped a huge six onto the roof of the stand, Ryder skied a Daren Powell delivery straight to Shawn Findlay to bring an end to his 23-ball innings of 21.
McCullum continued his high-octane knock, dishing out further punishment to Fidel Edwards, who conceded 46 runs in five wicketless overs, and Powell.
Lionel Baker's (1-36) introduction into the attack proved fruitful as McCullum walked down the wicket looking for another boundary only to send the ball straight to Findlay, leaving New Zealand on 96-2.
The wicketkeeper's quickfire 41 included six fours and a six off just 28 balls.
Guptill made 45 off 39 balls before being caught behind off Kieron Pollard (1-40).
Daniel Flynn was caught and bowled by Powell (3-66) for 21 and the fast bowler struck again immediately, trapping Neil Broom lbw for a duck, to leave New Zealand at 175-5.
By the time the rain came after 35 overs Taylor and Elliott (14no) had pushed the score up to 211-5. The Duckworth-Lewis calculation confirmed New Zealand as winners by nine runs.
The Black Caps take the five-match series 2-1. The first and fourth games were washed out.
