Fleming hammered 102 off 92 balls while Hamish Marshall, who fitting ended the chase with a massive six over mid-wicket, scored exactly 50 as the Kiwis raced to 178-1 in just 29.2 overs for their second straight win in the Super Eight.

On the other hand, Bangladesh's second defeat after a 10-wicket demolition by Australia on Saturday was never in doubt after the Tigers were bowled out for 174 in 48.3 overs on a batting-friendly wicket and under glorious sunshine.

The only casualty in the New Zealand chase was Peter Fulton, who was caught at mid-off by Tamim Iqbal off left-arm paceman Syed Rasel after scoring 15.

Fleming struck ten fours and three sixes in his match-winning knock. Marshall, who shared 144 runs for the unbroken second wicket with his captain, struck two fours and the six off left-arm spinner Mohammad Rafique that brought up his 50.

Earlier, Rafique entertained the crowd with some lusty blows that included two sixes off Scott Styris. The left-hander, who was unbeaten on 30 off 36 balls, shared 34 runs with Syed Rasel for the last wicket to give the Bangladesh total some respectability after the Tigers were reduced to 140-9 in 42.3 overs.

A surprise package in the second round, Bangladesh never looked to pose any serious threat against a team they beat in a practice match ahead of the showpiece event.

They lost wickets at regular intervals despite a sedate yet productive 55-run opening stand between Tamim Iqbal and Javed Omar, who replaced out-of-form opener Shahriar Nafees, after New Zealand captain Stephan Fleming sent Bangladesh into bat.

The rot started when left-handed Tamim (29) was smartly stumped by Brendan McCullum in the 16th over. Making his World Cup debut, Javed scored 22 before edging a simple catch behind the wicket.

Aftab Ahmed and Shakib Al Hasan added 43 runs for the third wicket. But Aftab, who was looking good, paid the price for going over the top and was caught at long-on after making 27 off 38 balls that contained three boundaries.

A fast and furious Shane Bond, who conceded only five runs in his first five overs, then returned for his second spell in the 36th over to knock off the stumps of Shakib (25) and wicketkeeper Mushfiqur Rahim (0) that effectively dismissed Bangladesh's chances of posting even a decent total.

Bangladesh captain Habibul Bashar (9) chased a second run only to find himself short of his crease before a direct throw from Jacob Oram broke the stumps.

Mohammad Ashraful (3) tried to run one down the thirdman but only managed to drag the ball on to his stumps.

Oram, who led the New Zealand attack with 3-30, made the initial breakthrough with two top order wickets and a run out before wrapping up the innings with nine balls to spare by bowling last man Rasal. Fellow all-rounder Scott Styris followed up with four for 43.

All the Bangladesh top order made it past 20 but no one was able to press on to a major score.

Bangladesh made two changes from the side with left-arm seamer Syed Rasal coming in for Tapash Baisya.

New Zealand were unchanged from the team that beat hosts the West Indies by seven wickets here Thursday.
