Afghanistan feeling the pressure of big score are commiting suicide by throwing the wickets away.
After the initial quick blows, the minnows lost skipper Nuwroz Mangal, Karim Sadiq and Asghar Stanikzai in matter of 10 balls to put England firmly in control of the match.
Mohammad Shahzad is on his way back to the pavillion as he skied on to Stuart Broad for one.
Shahzad looking to blast Finn out of the ground, got it high on the bat -- too quick for the bumpy batsman.
One ball later Jade Dernbach strikes as he removes Shafiqullah for a duck. Afghans are commiting a suicide here as they are throwing their bat at everything.
Nasir Hossain is showing some intent. A boundary off Southee helps him reach his second half century in T20 internationals.
However, the bowler hit backs two balls later, having Hossain (50) caught by Guptill at long on.
Oram has Mortaza (5) caught by Franklin at short third man. Sunny (5) hits straight to Oram in the final over to give Southee his third wicket for the match.
Bangladesh manage to score only 132 for eight in their stipulated 20 overs to lose by a whopping 59 runs.
This emphatic win all but assures the Black Cap a place in the Super Eights.
After Mills and Southee used the new ball to good effect, Daniel Vettori and Nathan McCullum are doing a good job with the old ball.
The Bangladeshi middle order is finding it difficult to cut loose. However, against the run of play Mahmudullah smashes a six over long on in Vettori's third over.
Oram replaces Vettori (3-0-21-0) in the 14th over and Nasir Hossain greets him with a six followed by a four as 12 runs come off the over.
The 50-run partnership for the fifth wicket is reached in the next over, bowled by McCullum. However, soon after Mahmudullah (15) hits the bowler straight to Williamson at long on.
Bangladesh staring at a heavy defeat at 87 for five after 15 overs.
Tamim Iqbal and Mohammad Ashraful open the batting for Bangladesh and it will be Kyle Mills first up for New Zealand.
Mills strikes with his third ball, having Iqbal caught by Guptill at cover even before Bangladesh had opened their account.
Shakib Al Hasan, the captain, comes out to bat and starts with a fortunate boundary. Ashraful also helps himself to a boundary as Bangladesh reach nine for one after the opening over.
McCullum and Franklin put on 94 runs, off just 71 balls, for the second wicket before Mortaza returns to have the latter caught by Elias Sunny at deep midwicket.
Franklin's almost run-a-ball 35 was inclusive of two boundaries and a six. His captain, Ross Taylor, comes in to the crease.
McCullum is dropped at extra cover when on 92. He goes on to complete his second T20 ton in the same Elias Sunny over.
McCullum's six off Shakib, the second of the New Zealand innings, ahs helped them get past the 50-run mark in the eighth over.
Mahmadullah is introduced into the attack in the ninth over, replacing Shafiul (2-0-19-0), and a till now subdued Franklin welcomes him with a boundary. His opening over costs Bangladesh 13 runs, with McCullum also helping himself to a boundary.
