The New Zealand cricket captain Daniel Vettori admits his side has been outplayed by Bangladesh in conceding the five-match ODI series.
Bangladesh won the fourth match by nine runs in Dhaka on Thursday night to take an unassailable 3-0 series lead.
It's Bangladesh's first ever series victory over a top-flight nation at full strength (they beat a severely depleted West Indies side 3-0 in the Caribbean last year).
And the loss leaves New Zealand with some serious questions to address ahead of next year's World Cup on the subcontinent.
Vettori says Bangladesh have shown them how to play in those conditions and they should have adapted quicker than they have.
And while Vettori's crediting the Bangladesh effort in the field, he blames his side's batting for the humiliating loss, young Kane Williamson aside.
The Bangladesh captain Shakib Al Hasan smashed 106 off 113 balls as they made 241, he then took three wickets as the Black Caps were dismissed for 232 with three balls to spare.
Williamson scored his maiden century, making 108, but was out in the last over.
Vettori says they must win the last match on Sunday night to restore some pride.
New Zealand tours India next month.
