Two late tries from wingers Julian Savea and Cory Jane gave the All Blacks a 21-5 victory over Argentina in their Rugby Championship match that was disrupted by a power cut in the port area of New Zealand's capital city on Saturday.

Wellington Regional Stadium, which sits on land adjacent to the port, was plunged into darkness during the halftime break because of the outage, which delayed the start of the second half by around 15 minutes.

Flyhalf Aaron Cruden added three penalties and converted Jane's try for the All Blacks, while Rodrigo Roncero scored the Pumas only points with a first-half try.

The All Blacks play South Africa in Dunedin next week, while the Pumas head to the Gold Coast in Australia to meet the Wallabies. - Reuters
