A captain's knock from Tom Latham and half-centuries scattered through the top order have guided the Blackcaps to their first one-day series victory in the Caribbean, defeating the West Indies by five wickets at Bridgetown, Barbados.
Chasing 302 to take the series, a 120-run partnership between Latham (69) and Daryl Mitchell (63), combined with half-centuries to Martin Guptill (57) and Devon Conway (56) to see New Zealand home with 17 balls to spare.
Needing a run a ball from the final six overs, a barrage of sixes from Jimmy Neesham sealed the deal, as he scored an unbeaten 34 from just 11 balls to end the wait for a series win.
The win is the Blackcaps' first one day international series victory on Caribbean soil, coming after last week's maiden Twenty20 series triumph.
Sent into bat by Latham, West Indies openers Kyle Mayers (105) and Shai Hope (51) made a measured start to the innings, before Mayers took the fight to the Blackcaps bowlers, blasting his way to a century off 106 balls.
But after Mayers reached his century, the Blackcaps struck twice in the space of three balls, dismissing both openers to bring two new batters to the crease and forcing the hosts to rebuild.
The next over, Daryl Mitchell snared a superb diving catch at cover, off the bowling of Mitchell Santner, to send Brandon King back to the pavilion.
The spinner then had Shamarh Brooks caught for a second wicket in as many overs, operating in tandem with Michael Bracewell to tame the West Indies run rate.
But captain Nicholas Pooran ensured his side weren't long on the backfoot, assailing the Kiwi attack with a flurry of boundaries, including two sixes in a single Bracewell over.
Pooran kept his foot on the accelerator through the crucial final 10 overs, slaughtering the Blackcaps attack, before he was caught in the deep in the penultimate over for 91 off just 55 balls, an innings that included a staggering nine sixes.
Alazarri Joseph (20 not out) stepped up in the dying stages with a useful cameo, blasting a six off the final delivery of the innings to lift his team's total above the 300-run mark.
Trent Boult finished as the pick of the Kiwi bowlers with 3/53 from his 10 overs, while Santner impressed with 2/38 from his spell.
In response, the Blackcaps were methodical in their chase. After losing second-match hero Finn Allen in the fourth over, Guptill found some much-needed form with a composed 57 from 64 balls, in partnership with Conway, adding 82 for the second wicket..
Conway also passed a half-century, taking 56 balls, before he was trapped leg before wicket by Yannic Cariah for 56 off 63.
At 128/3 and needing a partnership, Latham and Mitchell ensured the Blackcaps kept pace through the middle overs, adding a 50-run stand at a run a ball and taking the total past 200.
Latham became the third Kiwi batter to post a half-century, taking 52 balls, while Mitchell raced to the mark in just 37 balls as their partnership went past 100.
Needing 62 from the final 10 overs, Mitchell holed out to long-on off the bowling of Akeal Hosein for a game-changing 63 from 49 balls at 248/4, before Latham also went, caught by Pooran off Jason Holder for 69.
But New Zealand needn't have worried, as Neesham came in at No.7 and cleared the rope four times as part of an unbeaten 48-run partnership with Bracewell (12 not out) to seal victory at the start of the 48th over.
The series ends the Blackcaps' winter tour, after limited overs victories in Ireland, Scotland and the Netherlands.
The Blackcaps are next in action against Australia for a three match ODI series in Cairns starting on September 6.
West Indies 301/8 (Mayers 105, Pooran 91; Boult 3/53) New Zealand 302/5 (Latham 69, Mitchell 63; Holder 2/37)
