CARDIFF, Nov 7 (Reuters) - New Zealand repelled a frenzied late challenge at the Millennium Stadium on Saturday to defeat Wales 19-12 and extinguish the home side's hopes of a first victory over the All Blacks since 1953.

In the final 10 minutes, with New Zealand leading 19-6, man-of-the-match Dan Carter pulled down replacement scrumhalf Martin Roberts with a tackle the crowd thought was clearly too high following a sizzling break by Shane Williams.

Alun Wyn Jones then galloped into empty territory after intercepting a pass from Jimmy Cowan but with the defence racing back desperately his attempted pass was knocked to the ground.

Two late penalties by Stephen Jones narrowed the gap but the final score was a fair reflection of the match although Wales coach Warren Gatland was unhappy that flyhalf Carter escaped punishment for his high tackle on Roberts.

"It was a hard, high tackle and a swinging arm. It should have been three points and a yellow card," he told a news conference.
