New Zealand captain Kane Williamson has backed pace duo Trent Boult and Tim Southee to fire in the opening Test against Bangladesh.
Fresh off a 3-0 Twenty20 international series whitewash, Williamson and the Black Caps head into Thursday's first Test in Wellington with Boult and Southee set to lead the way.
In New Zealand's last Test series, Southee finished with 13 wickets in the 2-0 win over Pakistan in November, while Boult claimed five of his own amid an indifferent run of form.
Williamson, however, is confident the pair can inspire the hosts.
"In recent years they've been looking to get back to that where the ball swung for a long period of time and they bowled quickly," Williamson said on Wednesday.
"They're certainly showing those signs again. Trent in the last T20 might have hit 145 or 146 which is really promising because we know when he's bowling fast and swinging it for a long time he's been one of the best bowlers in the world.
"We'll be hoping for more of that going into a lot of test matches in the next while."
Of Boult, Williamson added: "To be fair he's been bowling really well and he's a world class performer. For a couple of years him and Tim were at the top of their game and they've still been bowling really well even if it hasn't been the best that they've wanted. That's the class of those two and they're certainly getting back to that point."
As for Bangladesh, batting remains an area of concern heading into the unlimited format of cricket.
While the bowlers have contributed, Mushfiqur Rahim's batsmen have struggled and the captain told reporters: "It is time that we prove ourselves in overseas conditions. The batsmen have to take the biggest challenge.
"Some of them like Tamim [Iqbal], Shakib [Al Hasan] and Mahmudullah have done well in tests here in the past but now we need a collective effort from the batsmen, which we failed to do in the ODIs and T20s. We are capable so this is our opportunity to do it."
