The Blackcaps have thumped Bangladesh by seven wickets in the third and final one-day international in in Mirpur overnight Tuesday.
The result seals a 2-0 series win for the New Zealanders - their first in Bangladesh in any format since 2008 - with the World Cup in India now just a week away. They won the second match by 86 runs, after the first was washed out.
A four-wicket haul from Adam Milne helped bundle the hosts out for a meagre total of 173 in just the 35th over.
The Blackcaps made light work of the run chase to knock off their target with 15 overs to spare, with opener Will Young's 70 off 80 balls guiding the way, backing up the 58 he scored in the first ODI.
Young struck 11 boundaries in his innings, joined by Henry Nicholls (53 off 50) in an third-wicket 81-run partnership that ensured they negotiated the Bangladesh score with minimal fuss.
Nicholls' effort took his run total for the tour to 143 runs, earning him player of the series.
Opener Finn Allen contributed a quickfire off 28 off 26 balls, with Tom Blundell helping steer the ship home with an undefeated 23 off 16.
Unfortunately for Dean Foxcroft, his international debut was shortlived - bowled by Shoriful Islam for a golden duck.
Also in the wickets for New Zealand were Trent Boult (2/33 off six overs) and Cole McConchie (2/18 off five), while Lockie Ferguson (1/26 off six) and Rachin Ravindra (1/20 off five) also chimed in.
Five players from Bangladesh will now assemble with the rest of the Blackcaps' World Cup squad in Hyderabad, India to face Pakistan on Friday, before their final warm-up match against South Africa in Kerala on Monday.
Their first World Cup group game is against England on October 5.
