Junaid Siddique hit a fantastic 85 to help Bangladesh to their first ever ODI win against New Zealand on Thursday.

Siddique had only managed 62 runs in his eight previous ODIs - at an average of just seven - but showed great temperament in compiling a match-winning 85 from 139 balls.

The 20-year-old left-hander fell with his team just seven runs short of New Zealand's target of 201 for nine, leaving captain Mohammad Ashraful (60 not out) to guide his side home to a comfortable seven-wicket win with 27 balls to spare.

The victory was Bangladesh's first against New Zealand in 13 ODIs and was made even more surprising given the tourists were without a number of their first-choice selection after 14 players were ruled ineligible after playing for the Dhaka Warriors in the unsanctioned Indian Champions League earlier this year.

The victory had been set up earlier in the day after the home bowlers restricted New Zealand to their lowest-ever total against Bangladesh - beating their 224 in Chittagong four years ago.

Mashrafe Mortaza was the destroyer-in-chief claiming four wickets, including three as the New Zealand top order crumbled to be 79 for six at one stage.

Jacob Oram (57) and captain Daniel Vettori steadied the ship with a 70-run stand, but it would ultimately not prove to be enough to allow Bangladesh to take a 1-0 lead in the three-game series.

The omens for a successful chase looked good when 19-year-old opener Tamim Iqbal stroked the first ball from Kyle Mills to the mid-off fence.

But Mills soon had his revenge in the fifth over when Iqbal (12) played a rash shot outside off stump to present Scott Styris with a simple chance at slip.

New Zealand had skittled Bangladesh for just 98 when the teams last met in Queenstown late last year, but any thoughts of the new-look hosts succumbing in the same manner were quickly put the bed with a confident 67-run stand between Siddique and Mushfiqur Rahim.

Wicketkeeper-batsman Rahim showed his comfort when stroking promising paceman Tim Southee over the mid-on fence to bring up the Bangladesh 50 from 13 overs.

The duo, both aged 20, had showed patience until the 24th over when, with his score on 30, Rahim skied a chance to Jesse Ryder on the mid-wicket boundary from the bowling of Styris.

Siddique almost followed soon after, but Styris failed to hold onto a return catch.

Siddique and Ashraful then set about taking the game away from the Kiwis in a 109-run stand that was only ended when Mark Gillespie had the left-hander caught by Oram just short of the victory target.

However, it was not long before the victory was sealed, Bangladesh's first in 27 games against Test-playing opposition, when Shakib Al Hasan (six not out) pushed Gillespie for the winning single.

Brendon McCullum had scored a 28-ball 80 when New Zealand took just six overs to beat Bangladesh in Queenstown last time out, and he set about with Ryder to inflict similar damage at the start of the Kiwi innings.

But, after adding 47 from the first eight overs, McCullum (14) fell when he was tempted by a wide delivery from Mortaza which flew to Syed Rasel at third man.

The wicketkeeper-batsman's dismissal would prompt a collapse of six wickets for just 32 runs that left the tourists reeling on 79 for six.

Mortaza did most of the damage as he claimed a further two top-order wickets, removing Ryder (34) and Jamie How (seven), while Abdur Razzak accounted for Styris (four) and Daniel Flynn (six) in quick succession.

It was left to the all-round talents of Oram and Vettori to stop the rot.

The duo used the experience from a combined total of more than 300 ODIs to frustrate Bangladesh and occupy the crease in a 70-run partnership in 19.1 overs.

Vettori fell in the 41st over for 30 when he attempted to sweep Shakib and was caught at fine leg by Naeem Islam.

Oram perished soon after when Abdur Razzak had him caught by Rasel and while Southee provided some late fireworks, hitting 19 off 14 balls, it would not prove nearly enough.
