'It's all about length'

Trent Boult bagged five wickets as Bangladesh were rolled for 126 in reply to New Zealand's mammoth 521 for six declared in the second Test on Monday.

Boult put the difference down to local knowledge.

"That's the beauty of Test cricket, the little subtleties that come with different grounds," he said.

"The wicket obviously offers a little bit of bounce with a bit of grass on it. Pretty good conditions, a little bit of swing, and I thought we used the bounce and pace that was on offer at this beautiful ground quite nicely."

"It's all about the length here, of us getting them on the front foot and encouraging them to drive down the ground ... pitching the ball up and hopefully we can get 10 (wickets) pretty quickly again."

Boult ended with five for 43 while Southee took three for 28.

Boult also became the fourth New Zealand bowler -- after Richard Hadlee, Daniel Vettori and Southee -- to claim 300 Test wickets.

"As a team, we're not about the milestones etcetera but it definitely does feel great to join an elusive club," Boult said.
