Upbeat New Zealand back same squad to deliver against Sri Lanka

New Zealand selectors have backed the same squad that held a rampaging England to a 1-1 draw to beat Sri Lanka in the two-test series starting in Christchurch next week.

They saw no need to tinker after New Zealand pulled off an incredible one-run win in the second test in Wellington on Tuesday after being asked to follow on by England captain Ben Stokes, coach Gary Stead said.

Opener Devon Conway was nursing a groin strain at the Basin Reserve and paceman Matt Henry had tightness in his back, but both were expected to be fit and available for Christchurch.

Faith in the playing group has been restored quickly, with Stead admitting after the 267-run defeat in the first test in Mount Maunganui that New Zealand were down on confidence.

"We felt that the 13 that we have here is the right 13 to go forward," he told reporters on Wednesday. "I think when you have a win like that (in Wellington), whether you win or lose, your confidence will improve."

Having won the inaugural World Test Championship (WTC) in 2021, New Zealand's title defence is already over, but the Sri Lanka series has ramifications for this year's championship.

Sri Lanka could sneak into the WTC final if they whitewash New Zealand and if Australia are swept by India in the ongoing four-test series.

Kane Williamson scored a century in a welcome return to form while wicketkeeper Tom Blundell had a terrific test with the bat and behind the stumps.

New Zealand's main concerns lie in
