The penalty count was a significant 14-6 in the Boks' favour.
When the All Blacks needed to staunch that first half damage they turned to the lineouts and picked off four of their rivals' throws.
One of the most significant came near the end as the Boks made a play for territory and a possible winning penalty from a lineout drive. Victor Matfield was on the field and set to take delivery from replacement hooker Adriaan Strauss.
Sam Whitelock rose to the same altitude and a touch in front of the Springbok legend. The All Black lock got the vital grab and the impending danger was shut down.
That small piece of skill was a massive sign about why the All Blacks have managed to lead the world for most of the last four years.
They find a way to win when they are battling some misfires. Sketchy possession meant they struggled to find some consistent veins of attack, although they were still good enough to claim two tries to none.
Richie McCaw dunked a clever pass over a defender into Jerome Kaino's touchline drive to the line and Ma'a Nonu drove on and on to leave Beauden Barrett an unimpeded dive for his try.
When they got a few chances the All Blacks played while the Boks, apart from a lively start, lacked much imagination about their tactics. Kick and chase and if that doesn't work, maul a bit, then kick and chase again.
At times the Boks have gone away from that formula and several recent duels with the All Blacks have been matches for the ages. But when the rewards and pressure rose to huge levels, the Springboks ambition shrank, they reverted to type and dragged the All Blacks down to their level.
It took all the All Blacks' concentration to unpick the humdrum and find a few golden corridors to the final.
