6.25pm

New Zealand. World. Test. Champions

With an aerial flick over square leg, Ross Taylor has taken New Zealand to their first world title in cricket 46 years after world championships started in cricket. They have worked hard for this title, and have raced against the dying sun and a high-quality team to get there. I am off to writing the full report. Here is a teaser for you. Please follow our live commentary for reactions.

Even the England weather couldn't summon enough cruelty to break the New Zealand hearts once again. Two years after they lost out on the ODI World Cup without actually losing the final, glorious late-evening sunshine saw New Zealand through to their first world title, the inaugural World Test Championship. It was well past regulation closing time on the reserve day, the sixth of the match, which featured only three-and-a-half days of actual cricket because of bad weather.

But what cricket it was. Two absolutely high-quality sides in extremely difficult conditions for batting combined to produce a thrilling contest of cricket in such little time. New Zealand needed to be highly efficient, consistent and skilful if they were to have a chance of winning this, and they managed it just in time.

6.25pm

Under two an over

It is there. They can touch it if they extend their arms. They need just 14 runs in 10 overs now. It is finally looking easy now. No bad light, no rain, no boundary countback. New Zealand are going to be champions of world Test cricket. At half past five in the morning back home in New Zealand.

6pm

Into the last hour

In the words of the great JR, "We have taken our last break, folks. We are not leaving here till we have a Test champion of the world."

Actually only New Zealand can win from here. But can some miracle deny them 35 runs in the remaining 15 overs? They have eight wickets in hand. It is so close they can smell it. Their first world title 46 years after cricket started the concept of world championships. Their two batting veterans have masterminded this tricky chase. Ross Taylor has taken the odd calculated risk, but Kane Williamson has only just punished errors. Both are striking at 44 per 100 balls, which is enough in this chase.

5.30pm

Pant is back

Rishabh Pant is back on the field. Wriddhiman Saha has left the field. India have separated the two spinners, and Jasprit Bumrah has had a catch dropped at first slip. New Zealand need 54 in 22 overs. Eight wickets still in hand.

5.20pm

Saha on the field

We have no information on what has happened to Rishabh Pant, but Wriddhiman Saha is keeping for India as of the start of the 29th over. Also, quite curiously, India are bowling two spinners in tandem.

That's reporting of facts done. I am not quite sure why India are bowling two spinners, especially when Ravindra Jadeja is not even looking threatening. New Zealand are racing against the dying sun here. If they use up all their 53 overs, it will be close to half past seven in Southampton. There is every chance light might become an issue. But two spinners speeds up the game.

New Zealand 84 for 2 in 30 overs. Need 55 in 23 overs. Jadeja ha bowled two overs for 11.

5.10pm

Halfway there

New Zealand now have 70 runs in a little over half the overs they have given themselves. They are 70 for 2 in 27 overs. This has come with Mohammed Shami perhaps beginning to tire. In two overs he has given away four balls to both Ross Taylor and Kane Williamson. Also Taylor took a calculated risk against R Ashwin to loft him over wide mid-on. Now India have gone to Ishant Sharma and Ravindra Jadeja.

4.45pm

Three an over

Time for a drinks break. The asking rate has now reached an even three an over, which is well above the going scoring rate in this Test. Light permitting, there will be another drinks break in 16 overs, and then the mandatory hour.

The bowling right now is really high quality. Mohammed Shami and R Ashwin are landing the ball where they want it, and sending it there the way they want it to. There is no risk-free run available. New Zealand feel it is too early to take that risk, and it really is. There is no way you want to give India even a sniff at winning this. Only four runs have come off the last six overs.

4.30pm

Ashwin the spanner in New Zealand works

India still have a hand on that mace. New Zealand will have to prise it out inch by inch. R Ashwin has trapped Devon Conway with a drifting offbreak that doesn't turn. This is a genius at work in conditions that are not suited for him. No bad balls from him all match. New Zealand 44 for 2 in 17.2 overs. Still need 95 in 35.4 overs. This is not a pitch where you take your eye off, swing casually, and suddenly you have lost 5 for 30. So New Zealand will want to guard against that before they get adventurous. Maybe go for it once the target is under 50? And that is a long way away.

4.05pm

Four, four, four, then a wicket

New Zealand have finally broken the shackles 20 minutes into the final session with three fours in Jasprit Bumrah's over, the 13th of the innings. In the 14th, though, R Ashwin has Tom Latham stumped as he looks to take another liberty. This is tense stuff. New Zealand 33 for 1 in 13.3 overs. Latham gone for 9 off 41.

New Zealand now need 106 in a possible 39.3 overs. The over-rate will be an issue, but from what we are hearing we are staying right here until a result is achieved or the overs are bowled. Provided the light remains good. And today we have a clear day, two days after the longest day of the year. That sunset is a long time away.

3.25pm

Last tea of this WTC

New Zealand have had to face eight testing overs, especially the four bowled by Mohammed Shami, which suggests forcing the pace will not be easy. New Zealand just can't afford any bad light here because it will be 3.45pm when we come back and they will probably need all of the 45 overs still remaining in the match. The sun is shining right now. They need 120 in the last session. The openers are unseparated. Come back for a massive last session.

2.45pm

In minutes starts the chase

New Zealand have made this team out of being calm and consistent. Can they keep their nerves in this last mile? Mind you, against this Indian bowling unit, this last mile could be more than just that. However, New Zealand will know they just need to bat normally for a while, rule out a defeat, and then hope the light stays long enough to get them the 53 overs. There have been so many near misses. And this is no cake walk. Scoring over two an over has been difficult in this Test. How are those palms yet?

India now know they need wickets. Not to win, but just to force a draw. They can't keep this run rate down without getting wickets. Not unless they can get the asking rate to fives and sixes for more 15 overs or so.

2.35pm

A tryst with destiny

With some great captaincy, New Zealand limit the damage India's tail intends to do. Mohammed Shami edges one over the slips for four, the lead is getting dangerous, and Kane Williamson sends out a fly slip. Shami swings again, and the man doesn't have to move. Jasprit Bumrah soon completes his pair. India bowled out for 170. New Zealand need 139 in a possible 53 overs. What a glorious finish in store. The sun is staying with us.

2.20pm

Matter of time

R Ashwin thinks he needs to throw his bat now that e has only nine, ten and Jack for company. He tries an almighty drive, and edges Trent Boult to first slip. India 156 for 8, leading by 124. Ashwin gone for 7 off 19. A possible 58.2 overs in the game.

2.15pm

Nicholls takes a stunner

Kapil Dev taking Viv Richards to set up India's first World Cup. Has Henry Nicholls done that with Rishabh Pant for their first World Cup? Pant has finally played one crazy shot too many and run out of luck. Skips at Trent Boult, and skies one (cue crucification comments), but this one goes up miles and is swirling. And suddenly if you see fielders running back and you look at Pant's luck in this innings, you think he might get away with this. The the camera focuses on Nicholls, who is assured in how much he has to run and is ready to watch it over his shoulder, which is the most difficult catch in the game. Yet you look at how steady it is, and you see he has it covered. In the end he has to put in a small dive, but he has it covered.

India 156 for 7, leading by 124. Pant gone for 41 off 88. A possible 58.4 overs in the game.

1.45pm

Wagner hour

Oh we are into the crazies. Neil Wagner is running in with a field set for the short ball, and has peppered both Rishabh Pant and Ravindra Jadeja before getting him nicking a length ball. The angle he creates from round the wicket is so good it needs to be checked for a no-ball. That's what makes New Zealand. When the pitch is not doing much for them, when things are not happening, they have Neil Wagner. What this barrage has done is stem the flow of runs first and then take the wicket too. And he has done this in the 10th over of his current spell, bowled either side of lunch.

India 142 for 6 in 62.5 overs. Leading by 110.

1.40pm

Rishabh Pant, an absolute original

After dancing down the wicket to almost everyone, now he is trying to counter Neil Wagner's short-ball barrage by trying to ramp-pull and reverse-pull. The second of those he pulled off too, keeping it down, and taking a single to third man. There might be some in the future, but there never hasn't been any like him in the past. While all this is happening, he has nearly run himself out trying to steal a single and being surprised by a kick-throw from Devon Conway.

India 142 for 5 in 62 overs. Leading by 110 with three-and-a-half regulation hours or 66 overs remaining.

1.10pm

Slight chaos

But chaos is also a ladder. New Zealand's official handle tweeted BJ Watling, in his last Test, was being substituted by Tom Blundell after he dislocated his finger in the first session. It appears there has been a late change of mind and Watling it is on the field. Anyway, what a session coming up. Watling will hope this is his last on the field. That India are not batting in the next session nor does Watling have to bat himself in that final session.

12.30pm

Final lunch of this WTC

Had you offered New Zealand the wickets of India's big three before this session, New Zealand would have taken it eyes closed, but that dropped catch and the subsequent quick runs might disappoint them a little. Twenty-five overs have gone for 66 runs and three wickets with Rishabh Pant dropped early and now unbeaten on 28 and in an unbroken 30-ball 21-run stand with Ravindra Jadeja. India lead by 98, have five wickets in hand, and they believe it is not about time but runs. The conditions, though, are not that difficult. The sun has been out, and relatively speaking, this is the best time to bat out there. Can't wait for the defining session coming up. See you soon.

12.15pm

Rishabh Pant, eh?

There will be more than a handful disapproving raises of eyebrows at the way Rishabh Pant has been batting here. Charging at Neil Wagner, swinging away, taking a lot of risks. He has been in control of two of every three balls he has faced. I am not going to go either way about his approach/method here, but I will just remind you his batting against Nathan Lyon at SCG was filled with more risk than what he has been doing here. Pant has not changed the way he bats. He got crucified for it before he was lionised for it, and you know what will happen if he skies one here. India 121 for 5 in 52 overs, leading 89, looking for quick runs.

12.05pm

New Zealand finally get a break

This partnership has been full of plays and misses and highly risky adventure, but in the end a nothing delivery down the leg side takes the glove from Ajinkya Rahane. Second leg-side strangle for Trent Boult this Test. Cricket, you bewitching sport. India 109 for 5. Leading by 77. Rahane gone for 15 off 40.

Noon

Pant, Rahane, stayin' alive

The way Rishabh Pant and Ajinkya Rahane have batted since that dropped catch, one thing is certain: they don't think just batting time is going to be enough to stop New Zealand. There has been much more attacking intent from them. These are the batters who like to attack when in doubt. Rahane has been beaten three times outside off by Trent Boult when hitting away from the body. Pant has been charging at Neil Wagner, and has managed to survive edges and plays and misses while hitting two boundaries too. The control percentage in this partnership hangs around 75, but India have put together 37 quickish runs.

11.30am

One hour gone

New Zealand have taken 2 for 25 in the first hour in 13 overs. They will have taken this if you had offered them at the start of the day, but on a day that, you'd imagine, New Zealand can't afford a mistake, how much will that drop of Rishabh Pant cost New Zealand? We might see a new form of attack post drinks. Neil Wagner to go short to Ajinkya Rahane again? He got him that way in New Zealand too and also in the first innings here. India 89 for 4 in 43 overs. Practically 57 for 4.

Andrew Miller sums up all the craziness of that hour here

It's accepted wisdom that India's stunning victory at Kolkata in 2000-01 changed forever the attitude of Test teams to the follow-on. The same could arguably be said about Adelaide 2006-07 and the third innings.

Even in the annals of English Ashes misery, Adelaide holds an especially hideous allure. But what transpired that final day has arguably informed the attitudes towards what is possible today in the World Test Championship final - even in a contest that has seemed a nailed-on draw all week.

Who in their right mind could look at a scoreline of 64 for 2 in the third innings after the week that we have endured, and genuinely believe that a contest could yet erupt? Pretty much everyone it turns out, not least Kyle Jamieson.

But, to dig back into the horrors of that December day, 15 years ago, a chasm of possibilities opened up beneath England's innings after an inopportune start to their day, much as India's batters will be feeling right now. Stick or twist? Hang tough or cut loose? Die wondering, or die hard?

At Adelaide, for rain, read runs - reams of them. Paul Collingwood made a double century, Kevin Pietersen made 158. Ricky Ponting responded with a monster of own, as both teams posted 500-plus first innings to leave the denouement an apparent formality. But then, at 59 for 1 on the final morning - a lead of 97 that was vastly more comfortable than India's overnight advantage of 32 - the doubts began to swirl. Andrew Strauss got a shocker, and Ian Bell lost his head. Pietersen, hours after declaring he'd mastered Shane Warne's leg-stump line, was bowled round his legs on the sweep.

And so it came down to the big question. Where now from here? Collingwood opted for dead-body attrition - clinging to the life-raft for 22 not out from 119 balls, but none of his team-mates dared to come out of their shells before they had been picked off by Warne, Brett Lee and Glenn McGrath. A slow, strung-out death ensued over the course of a mesmerising afternoon, until Australia were left with a 168-run victory gallop in the final session.

And so at drinks, India are 57 runs to the good, with six wickets liable to be lost before the close. Stick or twist? Rishabh Pant, his mind arguably made up following his tentative reprieve at slip, tends to know only one way. It may be his team's best option from here.

11.20am

Slippery Southee

There has been some excellent slip catching displayed by New Zealand this summer. Not just this summer but this WTC cycle and beyond. However, Tim Southee, who took a lovely low catch for the firs wicket of the match, has now dropped two. Rishabh Pant nearly provided an action replay of his first-innings dismissal off Kyle Jamieson, Southee went in front of first slip, had it at a comfortable catching height, but spilled it. This one was easier than his drop of Ravindra Jadeja in the first innings. Can New Zealand keep producing enough opportunities to make up for this?

India 85 for 4 in 41 overs, leading by 53.

11.05am

His Highness Kyle Jamieson

In the most batting-friendly conditions of this Test, against one of the best batters of all time, Kyle Jamieson works out a wicket when things did begin to look flat. Virat Kohli will of course not be happy with the dismissal but Jamieson has also set this dismissal up.

Seamers all over keep looking to drag Kohli across and then bowl the lbw ball, which is how Jamieson got him in the first innings. Here, though, there hasn't been enough seam movement available. So Jamieson has gone both ways: bowl an outswinger, then go wide on the crease looking for the lbw. The outswinger missed the edge, the one from wide of the crease did too much. Then he also went into the locker for bounce from short of a length. Kohli left one alone, but with this eventual one, he just pushed, which is the half-way thing that used to get him out in 2014. Neither going hard nor leaving it alone. Tall bowlers who have shown previously they can bring it in tend to do that to you. Kohli gone for 13 off 29. Jamieson to Kohli in Test cricket: 84 balls, 30 runs, three wickets.

And while I type it out, Jamieson has done the same to Cheteshwar Pujara. He has these batters looking for the ball coming in. Pujara is worried about it, moves forward to a length ball and tries to cover that movement, but the ball holds its line for an edge through to first slip. Pujara gone for 15 off 80. India 72 for 4, having added just 8 runs in 35 minutes. India lead by 40.

Last dance with MaryJane

And so it has come to this. Final day of the Test, the reserve day, to decide who takes the World Test Championship. It would appear India's best shot now is to share it with New Zealand but stranger things have happened in cricket. How many overs do New Zealand realistically need to bat to win? If they can tie India up, they could even win this in 45, meaning they need to take the remaining eight Indian wicket in 50 overs. If they bowl economically, that is.

There will be a lot of discussion on how these sides will approach this final day, but I think they will just play their normal cricket. Cheteshwar Pujara won't suddenly try to set up a declaration, and Virat Kohli won't suddenly shut shop. Don't forget that batting time is not the only route available to India. Scoring runs also plays New Zealand out.

New Zealand, too, will look to bowl normally. Keep the runs down, bowl good balls, and create about 80-90 false responses. They have five seam bowlers. They will just hope for more help from the pitch than they got in the evening session.

The weather, as if to tease us, is glorious finally. Is it too late? Or do we have a glorious final session still left? Drawing and sharing the trophy is all well and good, but nothing is quite the same as winning it outright. Does a side have enough skill, luck and time? We will start finding out in half an hour.
