And after that release of pressure, South Africa turn back to their pace spearhead Dale Steyn (and his mad, staring eyes). Elliott, who's getting a litlte bottled up at times, brings up the fifty partnership with a well-run three to deep extra cover. 99 more needed from 78 balls - 13 overs left, and Steyn can only bowl four.

"Ideally, South Africa want Anderson out. They don't want to have to bowl at him during the powerplay overs."

"How are your nerves? Eden Park is alive once more, awoken by the spirit of Corey Anderson. For the first time in a little while, you feel the momentum is with New Zealand. The Auckland crowd knows it too."

For the first time in this innings, we have spin at both ends as off-spinner JP Duminy returns. A lot of beards on show in this game... While Duminy boosts the score with a wide, his fifth over only yields four singles and a two until a knee-high full toss - shades of Steve Smith's bowling - is hammered for an 82m six over the bowler's head by Anderson. A much better over for the co-hosts.

"Only a couple of batsmen have been able to pick Imran Tahir in this World Cup. He is bowling with so much variety."

Tahir bounces in, Corey Anderson - briefly the holder of the fastest ODI century title - doesn't look like he's dealing too well with the leg-spinner, only four singles are possible from the over - leaving the co-hosts needing 116 from 15 overs (90 balls).

Jay: I'm amazed that people are writing off New Zealand. If they don't lose a wicket for four overs, I can see the South Africans panicking.

The 12th men and the giants drinks bottle flee Eden Park, where South Africa have had a "huddle" and an intense pep-talk from captain AB de Villiers. Philander to bowl his eighth over - under the reduced-overs formula, no-one can bowl more than nine. Grant Elliott - born in South Africa, lest we forget - is getting a little bogged down at times, but waits to thread a four through the covers. A single off the last ball takes him to 25 from 28 balls... but with a required rate of nearly 7.5, he will have to get a shift on at some point.

"It is still in the balance this game, but I think the pendulum is now swinging towards South Africa."

With the pacemen rotated at one end (Philander now with 0-47 from seven), the two spinners have been operating from the other end. Imran Tahir is back on in place of Duminy, he's quickly through his over and puts the brakes on with just a single from it. The players have earned some drinks - New Zealand need 124 from 17 overs.

Mark Pownall: Can't see New Zealand coming back from this now

#RugbyLI: Huge wicket for the Proteas, Taylor gone. Gonna be tough for NZ now from here I reckon.

Anderson, who you can imagine as a burly woodcutter wielding a giant axe, again finds Philander difficult to get away for the first four balls - but then heaves a two towards cow corner, and then one swing of his mighty forearms later, a shorter delivery is hoisted into the crowd behind mid-wicket for six.

We'd normally be at the halfway mark of the innings here - but if you weren't with us for the long rain delay earlier, this is now a 43-over game with Duckworth and Lewis having set New Zealand 298 to win.

"If New Zealand keep their wickets they will win this game."

Richie O'HaraBeamand: With that wicket South Africa become favourites and we can drop the question of 'can they perform under pressure', battled back into this.

Elliott adds a single to bring the left-handed Anderson on strike against Duminy's off-spin. South Africa crowd him with a leg slip and a silly point, but Anderson fluently sweeps for four. A single takes him into double figures. The right-handed Elliott also powerfully sweeps for four, bisecting short fine leg and the man on the square leg boundary. 10 from the over.

Ex-New Zealand captain on BBC Test Match Special

"The run-rate is now over seven, for the first time since New Zealand took guard and McCullum did his pyrotechnic thing. New Zealand are starting to feel the weight on their shoulders a bit.

"Anderson is normally a hitter. Is this situation going to prune that instinct? Pressure does funny things to you. South Africa sense that this game has changed."

Philander finds a bit of movement to discomfort Anderson, but after four dot balls, the beefy left-hander drills a fuller delivery for four back past the non-striker. That's the only scoring stroke from the over.

The Black Caps need 143 from 120 balls, and the required rate is up to over seven. And good news for South Africa - Dale Steyn is back on the field.

Stephan Shemilt

"Is that the ball game? Where once Eden Park was raucous, its hope is now slipping away. The noise is dimmed, there are plenty of orange shirts on seats, looking glum. South Africa are crushing the New Zealand dream."

Thanks, Phil. New Zealand reached the halfway point of their run chase almost exactly halfway through their allocation of overs - but then lost their fourth wicket. South Africa continue to rotate their pace trio at one end - Vernon Philander to bowl.
