Vettori remains concerned about New Zealand's batting

New Zealand completed their rout of Bangladesh on the third morning of the second Test, winning by an innings and 137 runs to clinch the series 2-0.

Bangladesh started the third day at 51-5 and the Test ended just before lunch with the tourists all out for 113, Tamim Iqbal unable to bat.

Former captain Stephen Fleming was unimpressed by New Zealand's execution, with a series against England next.

"We've dominated but I don't think we'll get too carried away," he said.

"If we're to compete we have to be more skilled."

"The nature of some of the outs [dismissals] was sloppy, mine included."

New Zealand captain Daniel Vettori was also at a loss to explain the batting shortcomings, with the hosts failing to reach 400 in two completed innings in the series.

"Why can't we bat long periods of time? It's a hard one to answer," said Vettori.

"We all know we have to get better at it."

This series has exposed the void there is between the top four or five sides and Bangladesh Jamie Siddons Bangladesh coach

On Monday only the final wicket pairing of Saqibul Hasan and Mashrafe Mortaza offered any substantial resistance.

They added 30 before a diving catch by Kyle Mills at point gave Jacob Oram the wicket of Mortaza for six.

Saqibul was left unbeaten on 41, the highest score by a Bangladeshi batsman in the Test.

Man of the match Chris Martin, who took five wickets in the first innings, was again the pick of the New Zealand bowlers with 2-35, while Mills, Oram and Iain O'Brien also took two wickets apiece.

O'Brien could have enjoyed a much better return had he not had four chances dropped off his bowling, all by Matthew Bell in the slips.

Bell's bout of butterfingers was part of a general malaise which saw the Test descend at times to the mediocre.

"This series has exposed the void there is between the top four or five sides and Bangladesh," said defeated coach Jamie Siddons.

England arrive in New Zealand on 28 January, playing two Twenty20 internationals and a five-match one-day series before three back-to-back Tests.
