Sabbir Rahmah chalked up his maiden one-day international century but early wobbles put paid to Bangladesh‘s hopes of avoiding a whitewash against New Zealand.
The Black Caps set the tourists a target of 331 for victory in this third ODI but were three down for two runs after two overs when Liton Das was bowled lbw for one off Tim Southee.
Southee already had claimed the wickets of Soumya Sarkar and opener Tamim Iqbal for ducks in a seven-ball spell and recorded figures of 6-65 in Dunedin as the hosts sealed an 88-run victory.
Rahman lacked support from the Bangladesh order and, by the time he passed 100, the tourists were needing nearly four a ball.
Southee got his sixth – and Bangladesh’s final – wicket when Rahman attempted a hefty pull which saw the bat fly out of his hands, with the Kiwi taking the catch.
If the tourists’ innings with the bat was mainly about one man, the Black Caps shared the runs around with a trio making half centuries.
Ross Taylor led the way with a knock of 69 and put on a 92-run stand for the third wicket with Henry Nicholls (64).
The home side put a Kane Williamson-less New Zealand in to bat, also bringing in Mitchell Santner and Southee for Todd Astle and Matt Henry.
Opening batsman Chris Munro was the first to fall, bowled lbw for eight off Mashrafe Mortaza.
Fellow opener Martin Guptill soon followed for 29, holing out to long-on, and unable to match his centuries at Napier and Christchurch.
New Zealand kept the scoreboard ticking over – captain Tom Latham contributed 59 – with a couple of quick wickets at the death seeing them post a score of 330 for six, before Bangladesh were bowled out in the 48th over for 242.
