Tin Southee was man of the match as New Zealand beat Bangladesh by nine wickets in the second test with a day to spare.
Bangladesh were skittled earlier for 173, gifting victory to New Zealand, after they requested an extra half-hour to complete the match rather than come back on day five.
Tom Latham and Colin de Grandhomme took only 10 minutes to make 41 and 33 respectively and the game was over.
A series of reckless dismissals on Monday undid the tourists' hard work from earlier in the test at Hagley Oval, leaving the Black Caps with a target of 109 to complete a 2-0 series sweep and 19 overs in fading light to achieve it on day four.
Tim Southee (three for 48) started the rot, claiming the cheap scalps of key pair Tamim Iqbal and Shakib Al Hasan before Bangladesh had wiped out the first-innings deficit of 65 runs.
Captain Tamim was caught playing an unnecessary hook to deep square leg while Shakib lamely stabbed a rising ball into gully.
Neil Wagner (three for 44) employed hostility and Trent Boult (three for 52) used reverse swing to run through the rest of an inexperienced line-up.
It transformed what had been a tight test at the start of play into a probable romp.
Opener Soumya Sarkar (36) and Mahmudullah (38) threatened, although their innings were based on flashy strokes rather than application.
Swing specialist Southee, who took five first-innings scalps, became the fifth New Zealander to claim 200 test wickets.
He is the second-fastest Kiwi to reach the mark, with his 56 tests, eclipsed only by the great Sir Richard Hadlee's 44.
It took lusty, career-high knocks from tailenders Taskin Ahmed (33) and Kamrul Islam (25 not out) to push the target past 100.
Bangladesh were equally profligate in the field as New Zealand, resuming at 260 for seven after day three was lost to rain, sped to 354 off a further 21.4 overs.
Two chances behind the wicket were botched, taking the tourists' tally of drops to six for the match.
Henry Nicholls advanced from 56 to a career-best 98, falling agonisingly short of three figures when bowled by spinner Mehedi Hasan.
The innings will nevertheless ease pressure on the 25-year-old's place in the team after a modest start to his career.
Wagner scored an eventful 26, ending with a dismissal that sent commentators scrambling for the law book.
He grounded his bat when completing a second run but it was back in the air when wicketkeeper Nurul Hasan took off the bails.
