New Zealand captain Daniel Vettori has admitted that his side was outplayed by Bangladesh in conceding the five-match ODI series 0-3 with one game to go. Bangladesh strung three wins on the trot against top opposition for the first time in their history to clinch the series, leaving New Zealand with some serious questions to address ahead of the World Cup on the subcontinent.

"Bangladesh have played better cricket than us and deserved the victory," Vettori said after the nine-run defeat in the fourth match. "They have shown us how to play in these conditions."

New Zealand began the must-win game well, reducing the hosts to 44 for 3, before Man-of-the-Match Shakib Al Hasan turned the tables with a century, setting a target of 242 in slow and low conditions. Bangladesh's bowlers kept the chase under control and it was down to Kane Williamson, who became the youngest centurion for New Zealand, to give his side a chance. His effort, however, was not enough to take them past the line.

"Kane's hundred is the positive to take out from this game," Vettori said. "We should have adapted quicker than we have. We put ourselves in tough positions with the bat. One game left, must win for us. We must restore some pride in the last game."
