Martin Guptill hit his second consecutive ODI century as New Zealand cantered to an eight-wicket victory over Bangladesh in Christchurch.
The Black Caps secured the three-match series in convincing fashion at Hagley Oval, chasing down a target of 227 in just 36.1 overs.
Opener Guptill, fresh from an unbeaten 117 in Napier, went one better on Saturday, eventually holing out for 118 after cracking 14 fours and four sixes during his 88-ball stay.
His 143-run partnership with Kane Williamson for the second wicket put New Zealand well on their way to victory.
Williamson, who was unbeaten on 65 from 86 deliveries, completed the victory via a boundary with 83 balls to spare.
After being sent in Bangladesh lost their openers inside seven overs with Liton Das caught on the boundary off Trent Boult for one before Tamim Iqbal was trapped lbw for five by Matt Henry.
Mohammad Mithun top-scored with 57 and Sabbir Rahman (43) was the other major contributor as the pair put on 75 for the sixth wicket.
However, the New Zealand attack were never stressed with pace bowler Lockie Ferguson (3-43) leading the way as Bangladesh were dismissed for 226 with two balls remaining.
In response, New Zealand were half way to their target within 19 overs for the loss of opener Henry Nicholls (14) who was caught at deep square leg off Mustafizur Rahman.
Rahman also claimed Guptill when only 39 at which point the home side only needed 39 leaving Williamson and Ross Taylor (21) to complete successive victories by eight wickets.
