New Zealand have clinched a record fifth straight test series victory, dispatching Bangladesh by an innings and 12 runs in a rain-shortened affair at Wellington's Basin Reserve.
After scoring 432/6 declared in their only innings with the bat - a lead of 221 runs - the Blackcaps dismissed their rivals for 209 before lunch on the final day, despite losing two days to weather.
Pace bowler Neil Wagner, who was denied a five-wicket bag in the first innings, achieved the milestone for the sixth time in tests, accounting for five of the last six wickets to fall.
Batsman Ross Taylor was named Man of the Match for his third career double-century.
Victory gave New Zealand a 2-0 lead in the three-test series, following previous success over Sri Lanka at home, Pakistan (away), England (home) and West Indies (home).
When play began on Tuesday, Northern Districts wicketkeeper Peter Bocock had earned a surprise call-up, after regular keeper BJ Watling injured a hamstring in warm-ups.
The newcomer had played just three first-class matches, taking 12 catches and scoring a half-century against Wellington in December.
The Blackcaps already had a substitute fielder in their ranks, with skipper Kane Williamson nursing a shoulder injury on the sidelines.
Williamson suffered the injury while fielding on Sunday and was in obvious discomfort during his 74-run innings with the bat. He visited Wellington Hospital for x-rays on Monday and an MRI (Magnetic Resonance Imaging) on Tuesday confirmed a tear that had him in doubt for the third test.
Bowler Tim Southee stepped into the captaincy, with New Zealand in a strong position, as they chased victory.
By stumps on Monday, the Blackcaps had their rivals wobbling at 80/3, with Trent Boult taking two wickets. He struck again on Tuesday morning, enticing Soumya Sarkar into a catch for Ross Taylor in the slips, as Bangladesh reached morning drinks at 133/4.
Before lunch, Wagner and Boult (4/52) cleaned up the Bangladesh tail, with the former claiming Mohammad Mithun (caught Southee), Liton Das (caught Boult), Taijul Islam (caught Tom Latham), Mahmudallah (caught Boult) and Ebadat Hossein (bowled) to finish with figures of 5/45.
The third test is scheduled for Christchurch's Hagleny Oval, starting Saturday.
