Bangladesh secured a stunning pre-World Cup warm-up victory over New Zealand at the 3Ws Stadium on Tuesday.

Set 227 for victory, the rank outsiders made it with two wickets in hand after tail-ender Mashrafe Mortaza blasted two successive sixes off James Franklin in the penultimate over.

Bangladesh had looked behind the clock for most of their run-chase after Jacob Oram, nursing a broken finger, had battered 88 in the New Zealanders' 226 all out.

They started in style with 17-year-old Tamim Iqbal tearing apart the Kiwi attack with a quickfire 46 from 48 balls including a huge six off Daniel Vettori.

His fellow opener Javed Omar weighed in with 45 but after those two had departed the Bangladesh innings lacked momentum until the late assault from fast bowler Mortaza.

He hit 30 from 14 balls including three sixes, one of which came off the bowling of New Zealand spearhead Shane Bond.

Mortaza had also shone with the ball, claiming four for 44.

Earlier, the hefty 28-year-old Oram had repaired the New Zealand innings at 75 for six when he and Brendon McCullum blasted a seventh-wicket 105-run partnership.
