Who to bowl? Four to go - Steyn has two, Philander, Morkel and Tahir have one apiece, while I doubt we'll see Duminy or De Villiers bowl again. It's leg-spinner Tahir who gets the nod. A Ronchi single is followed by two dot balls - 35 from 21.

Two more singles mean it's 10 off the over. 36 from 24 balls needed, and a lot now rests on Elliott, who has 62 from 60 balls. Can Ronchi stay with him, or will it be the fairytale ending for old man Vettori to come in and hit the winning runs?

Peter Archer: That bad run out miss by De Villiers will be the winning of the semi-final by New Zealand. Pivotal moment in this intriguing match.

Half-tracker, and Elliott launches it over one of the bigger boundaries, into the crowd behind mid-wicket. 38 from 26.

Emmanuel Kamara: A great game. New Zealand vs South Africa. Nerves will definitely go up for the last few overs but guess they can handle it.

Mark Kelly: That wicket helps but it changes nothing. SA still need to take another one otherwise 46 in 30 is do-able.

De Villiers to bowl the last "part-time" over, and Elliott adds a single to bring the new man Luke Ronchi on strike. Wicket-to-wicket from De Villiers, Ronchi steers him down the ground for a single to long-on. 44 from 27 balls.

"You couldn't make it up. 'Wicket this ball,' says Graeme Swann, just before Corey Anderson skies the ball into the Auckland night. 'There was just too much pressure created by that over'."

"A fantastic over from Morkel. A bit of pace, a bit of bounce. Anderson missed a hook the ball before, but all he got was underneath it and the ball went very high."

Scorecard

And South Africa finally break the partnership - having dried up the runs with dot balls, Morkel fires in a bouncer which Anderson sends sailing into the stratosphere and there's snow on it by the time Faf du Plessis takes the catch. Or does he? There's a heart-rending couple of minutes while the umpires look at the replays - did the ball hit the wires of Spidercam? Apparently not - Anderson has to go.

The stadium DJ plays Michael Jackson's "Thriller". 46 from 30 balls? I'd call that a thriller. But it may be "close to midnight" by the time this game finishes...

Andrew Samson
BBC Test Match Special statistician

"The highest successful run chase in any World Cup knockout game is the 289-4 Australia scored to beat New Zealand by six wickets in the quarter-final in Madras in 1996."

Tahir off, Morkel on as the skipper shuffles his front-line bowlers. With the game ebbing and flowing with nearly every delivery, the crowd is silenced after the Kiwis only manage a single off the first half of the over.

"It has been a very good partnership. New Zealand were in all kinds of trouble when Anderson came out to bat. They have worked it methodically to put themselves into this position. I'm enjoying this contest."

ABDV needs to find two more fifth-bowler overs from somewhere - so he comes back on himself. There's an appeal for leg before as Elliott tries to swing across the line - it looked quite high, and South Africa have no reviews left.

De Villiers fervently wipes the ball with a towel between deliveries as New Zealand keep plugging away with singles, but his last ball is too loose down the leg side and Anderson smashes it away for four through fine leg to bring up the century stand. 47 needed from 36 balls. Who's your money on?

"You favour New Zealand slightly just because of the number of wickets they have left."

"I'm very jittery in my seat. The best four teams are playing this week. And we have no idea who is going to win this match. It's still 50-50."

And now it's Elliott's turn to reach his half-century from a slightly slower 53 balls, lofting a four over extra cover. New Zealand are rather getting after Tahir here, and there is a feeling that the pendulum has swung Kiwi-wards. They need 55 from 42 balls.

BBC Radio Test Match Special

On Twitter: Nobody is leaving Eden Park. It is an absolute thriller.

It looks like South Africa want the ball changed - a tactic TMS legend Henry Blofeld refers to as "ballsmanship". After a brief visit from the fourth umpire and his attache-case full of additional spheres, the Proteas are told to get on with it. Imran Tahir back into the attack, but Anderson is in the zone now, smacking Tahir for a four square of the wicket before bringing up his fourth ODI fifty from 47 balls.

"Imran Tahir could break the game. He is such a fierce competitor."
