Dunedin: New Zealand crushed Bangladesh by nine wickets to win their first Test shortly before tea on the third day at University Oval here on Sunday.
Set 35 to win after Bangla batting collapsed, Kiwis reached their target in 8.1 overs for the loss of one wicket with Peter Fulton sealing the win with a massive six off Mohammad Ashraful.
Bangladesh had resumed their second innings on 148 without loss, but succumbed to a spectacular collapse, losing all 10 wickets to be dismissed for 254 just after lunch.
New Zealand captain Daniel Vettori chopped off the tail after lunch to take four wickets for 70 runs after seamer Kyle Mills gave the visitors the much needed breakthrough when he castled Tamim Iqbal in the morning session.
Vettori said the New Zealand bowlers had lifted their game after falling into the trap of underestimating Bangladesh having knocked them over for 137 in the first innings.
"We got caught up in thinking we'd run through them again so there was a lot of talk about what we needed to do," Vettori told a news conference.
"It came back to me to set appropriate fields and give the bowlers the right conditions they could thrive in."
Despite the relatively easy nature of his team's win, Vettori said his side still had some improvement in them ahead of the second Test starting in Wellington on Saturday.
All-rounder Jacob Oram and recalled opener Matthew Bell both scored centuries in New Zealand's first innings of 357 but no-one else made it to 35.
"In the past it's taken us a couple of Tests matches to actually learn what we have to do to get better -- to flip the switch overnight was pleasing," Vettori said.
"(But) if you take Jacob and Matthew out of the equation, it wasn't a great batting performance."
Bangladesh's Australian coach Jamie Siddons said he was at a loss to explain his team's collapse after the opening pair had put on 161.
"I went to bed thinking the worst, and the boys didn't let me down. It's what I've seen all tour .... I'm still looking for the answers."
The end came quickly for Bangladesh when Mills bowled Tamim Iqbal for 84 after the 18-year-old had celebrated his Test debut with half-centuries in each innings.
Chris Martin then dismissed opener Junaid Siddique for 74 in the next over, caught by Stephen Fleming at first slip, as New Zealand's bowlers began to close in for the kill.
Oram, who was named man of the match, removed Habibul Bashar for 11, caught in the gully by Mathew Sinclair, before Iain O'Brien made a double breakthrough just before lunch.
Cumming held a sharp catch at backward point to dismiss Ashraful then Aftab Ahmed went without scoring for the second time in the match when he was caught by Bell at cover as the tourists limped to lunch on 206 for five.
Vettori cleaned up Shariah Nafees (28), Mushfiqur Rahim (six), Mortaza (10) and Shahadat Hossain (no score) after lunch before Martin got the last wicket, Sajidul Islam, for one.
Bangladesh picked up a consolation wicket when Mortaza trapped Cumming lbw for four but Bell (20 not out) and Fulton (15 not out) steered the Kiwis to a comfortable victory.
