Another stoppage now as Flip van der Merwe receives some treatment.
du Plessis has another two minutes in the bin and there are 15 minutes left in the first half.
Nonu takes on the South African midfield now and he makes his way over the half way line. Eventually the ball is turned over and Kirchner sends a monster kick downfield.
Boks with the net gain after that kick-fest. Now they spread the ball across the ABs 22.
But the ball has been knocked on. And du Plessis is back on. So one bad, one good there for South Africa.
ABs scrum on their own 22. 14 minutes left in the half.
33 MINS - ALL BLACKS 14 SOUTH AFRICA 10
Nonu very nearly gets an interception, but it wouldn't have counted anyway due to an earlier knock on. SA scrum.
It would be nice to get through a scrum. Everyone so far has ended with a whistle.
Everytime the Boks work there way into a decent try scoring position, they cough the ball up. Whether it's by knock-on, or a misplaced pass it just isn't clicking in that final third.
But they have another chance now. Boks lineout from 10m out.
They set up the rolling maul, over the 5m line they go. TRY SOUTH AFRICA.
And it's Bismarck du Plessis who gets the ball down. What a half for the South African No.2.
They got set early from the lineout and pushed over from 10m out. Great ball security, belief and confidence from the Boks pack.
Steyn judges the conversion perfectly. ABs 14 SA 10.
Penalty All Blacks. Barrett sends one over from 25 metres after the Boks were penalised for an illegal block from a clearance kick.
47 MINS - ALL BLACKS 24 SOUTH AFRICA 10
Five minutes left in the first half? Who has juice left in the tank, it's been a bruising, bloody first half.
ABs knock it on, Boks now 10m out and running at the line strongly.
Steyn brougth down 6m short.
Big All Blacks defence. du Plessis is smashed in a tackle.
All Blacks turn it over. Great defence and eventually Conrad Smith belts the ball away down field.
Just over two minutes to play in the first half and Messam has the ball deep in the ABs half.
Barrett clears into touch on halfway and everyone takes a breath. The Boks just had a series of powerful raids on the ABs line from close range, but the home side stood so strong. A real highlight for Steve Hansen there.
The halftime siren sounds now as the ABs swing the ball wide for one last crack at the line.
But the ball goes down and the halftime whistle sounds. What a cracking half.
