All the action from the first quarter-final in Melbourne.
80mins: The final whistle is blown after Ali Williams is brought down inches from the line.
78mins: Spencer releases Howlett with a sublime pass that is adjudged marginally forward, much to the chagrin of the crowd.
76mins: Brad Thorne gets his hands on the ball and instantly makes good yardage upfield as Joost van der Westhuizen leaves the field in a Springbok shirt for the last time.
74mins: Richie McCaw goes to the floor with what looks like a nasty cut to the head. The number seven is finally led off as both sides make numerous changes.
72mins: The third try finally arrives - with Spencer again involved - as the fly-half flips the ball through his legs to Rokocoko who simply dives over in the corner. MacDonald's kick goes wide.
New Zealand 29-9 South Africa
71mins: Two steps from Spencer starts a great move with Collins and Melamu driving forward, but the ball is knocked on with the line beckoning.
69mins: The game becomes a scrappy affair as the Springboks attempt to run everything and, more often than not, knock on.
68mins: MacDonald slots a straightforward penalty to push his side 15 points ahead with 12 minutes to go.
New Zealand 24-9 South Africa
62mins: Christo Bezuidenhout is picked up and carried into touch inches from the line by Justin Marshall and Joe Rokocoko.
61mins: Schalk Burger comes on for Danie Rossouw as the Boks kick for the corner after earning a penalty.

New Zealand 21-9 South Africa
55mins: Mauger knocks on after a heavy tackle and Jaco van der Westhuyzen runs the ball out of defence only to find a lock, a prop and a hooker outside him. Unsurprisingly, the move fails to reach the halfway line.
54mins: Justin Marshall is forced out into the corner after some intense pressure - but South Africa will not take a backward step on their own line.
53mins: Kiwi number eight Collins charges downfield after a powerful hand-off . Spencer comes close with two dance-like steps to wrongfoot the defence, yards from the line.
50mins: Hougaard 's attempted break on the 22 earns a well deserved penalty for the Boks. The Blue Bulls fly-half trebles his tally.
New Zealand 16-9 South Africa
48mins: Springbok hooker John Smit is involved in an impressive passage of running rugby by the Boks - as the All Blacks knock on. Kees Meeuws replaces Dave Hewett for the Kiwis as a blood replacement.

New Zealand 13-6 South Africa
37mins: South Africa earn their best field position so far - with a scrum inside the 22. Number eight Juan Smith and Joost van der Westhuizen combine well - but the scrum-half is forced out near the corner flag.
34mins: The Springboks have a clear overlap but needlessly spill the ball - and they continue to kick what little possession they have, away.
32mins: After half an hour, the Boks finally secure some ball and attempt to spread it wide. But De Wet Barry is stopped and the Kiwis win a penalty for offside. MacDonald adds his third kick of the night.
New Zealand 13-3 South Africa
28mins: Hougaard again finds himself clearing from behind his own line as the pressure builds. The omens do not look good for South Africa who simply cannot get their hands on the ball.
26mins: Aaron Mauger glides through the Springbok defence but Corne Krige brings him down with a captain's tackle to save a certain try.
25mins: Spencer's second drop goal - this time from directly in front of the sticks - again goes wide, as the crowd jeer the decision not to keep the ball in hand.

18mins: Hougaard attempts a long-range drop goal but the ball flies wide.
17mins: Carlos Spencer jinks through two tackles and outflanks four more with a burst of pace just outside his 22, to release MacDonald who touches over with ease. The centre adds the extras.
New Zealand 10-3 South Africa
15mins: All Black number eight Jerry Collins mysteriously runs the ball into touch without a hand being laid on him.
14mins: South Africa earns a penalty chance directly from the re-start when Mealamu is penalised for holding on, on the floor. Derick Hougaard brings the scores level.
New Zealand 3-3 South Africa
13mins: A superb drive from the pack pushes South Africa back onto their own, thanks to some powerful work from Chris Jack and hooker Keven Mealamu. Leon MacDonald's kicks sails through.
