Cape Town - A power failure delayed the second half of the Rugby Championship Test between New Zealand and Argentina at Westpac Stadium in Wellington on Saturday.

The All Blacks were leading 6-5 at half-time in a game played in atrocious weather conditions.

Just as the players were ready to head back for the second period the lights faded, leaving the stadium plunged in darkness.

It took organisers about 10 minutes to get the lights back on for play to resume, effectively giving the players a 20-minute half-time break.

Argentinean prop Rodrigo Roncero scored the only try so far in the game, while All Black flyhalf Aaron Cruden kicked two penalties to give his side a slender lead at the break.

The All Blacks currently top the Rugby Championship standings with two wins from two (8 points), while Argentina are in third spot (2 points), with one loss and a draw to South Africa.

South Africa (6) are second, while Australia make up the rear with zero log points. The Boks and the Wallabies clash in Perth (12:35 SA time) later on Saturday.
