Kiwi kings stun India to win World Test Championship

New Zealand have shed their bridesmaid tag by claiming the inaugural World Test Championship (WTC) title with an eight-wicket victory against India in a thrilling final.

Beaten in the finals of the last two 50-overs World Cups, Kane Williamson's team became Test cricket's first official world champions after prevailing in a match plagued by bad weather before a superb finish at the Hampshire Bowl on its reserve day on Wednesday.

All three results looked possible when India resumed the final day on 2-64 in their second innings with captain Virat Kohli and the dour Cheteshwar Pujara in the middle.

Kyle Jamieson had been the wrecker-in-chief in India's first innings and the towering seamer returned to haunt them again on the sixth morning.

The 2.03m-tall bowler dismissed Kohli and Pujara in his successive overs but was denied a third wicket when Tim Southee dropped Rishabh Pant at second slip when he was on five.

It threatened to be a costly reprieve as Pant counter-attacked with a typically aggressive knock of 41.

It took an inspired bowling change by Williamson to end the mayhem with Trent Boult (3-39) removing Pant and Ravichandran Ashwin in the same over.

Southee (4-48) polished off the tail as India, who had managed 217 in the first innings, folded for 170 in the second.

Chasing 139 to win from 53 overs, New Zealand did not find it easy as Ashwin dismissed both openers to inject fresh excitement into the contest.

More drama followed as Williamson, who made 52 not out, was adjudged lbw to Ashwin early in his innings. Williamson immediately reviewed the decision and got it overturned.

He got another life when Jasprit Bumrah dropped a skier as New Zealand closed in on victory.

Ross Taylor, whose 47 not out included the winning boundary, was also dropped by Pujara in the slips when he was on 26.

"Certainly it's a very special feeling. After a couple of close ones (in ICC finals), nice to get one under the belt," Williamson said at the presentation ceremony.

"I've been part of (New Zealand cricket) for a short while, but it's a very special feeling, the first time in our history we've come away with a world title."

The final marked the culmination of a two-year cycle of the WTC, which was launched in 2019 to create Test cricket's pinnacle.

New Zealand's victory was also a fitting farewell for their wicketkeeper BJ Watling who retired after this match.

India captain Virat Kohli blamed his team's batting on the final morning for their defeat.

"The Kiwi bowlers executed their plans to perfection and kept putting us under pressure and did not allow scoring opportunities,” he said.

"I think in the end, we were 30-40 runs short of putting them under serious pressure in the last innings."

Jamieson, who claimed his fifth five-wicket haul in his eighth Test, was adjudged player of the match.

New Zealand took home the ICC Test Championship mace and pocketed $US1.6 million ($A2.1 million).
