New Zealand won a tight game with South Africa to continue their good form and extend their lead at the top of the Tri-Nations table.

Although the game finished 19-0 in the All Blacks’ favour, it was only 5-0 heading into the final quarter.

Conrad Smith got the first try early on but it was much later when Dan Carter finally sealed the win, before Keven Mealamu added a third late on.

Carter completed two conversions after missing a host of kicking chances in the first half.
