New Zealand shut out South Africa 21-0 in the Wellington final to complete one of the great second-day performances at an International Rugby Board world sevens series tournament.
The series defending champions also reclaimed the lead in the nine-leg circuit with four tournaments to play, inching two points ahead of the South Africans, who had won the last two finals.
While the Blitzbokke had beaten New Zealand in both of those deciders - at Port Elizabeth and Las Vegas - they weren't in the contest on Saturday against a home side who won the popular Wellington tournament for the seventh time in 15 editions.
All three converted tries came in the first half, with two to wing Sherwin Stowers giving him a tournament-best eight.
The opener, to Tim Mikkelson, was the first try South Africa conceded for the day after having beaten Australia and Fiji by the same 10-0 scoreline earlier on Saturday.
However, that record didn't stack up against New Zealand's, who scored 76 unanswered points in their three games, beating Canada 24-0 in the quarter-finals and England 31-0 in the semi-finals.
After losing their opening pool match to Fiji 12-7, New Zealand bounced back to score a remarkable 178 points without conceding any.
They adapted best to wet conditions on Saturday, employing a long kicking game and attacking opposition ruck ball effectively.
The speed and sevens nous of players like Mikkelson, Stowers and Gillies Kaka proved the difference in the big games, along with a ferocious team defence.
South Africa spent the last five minutes of the final on attack but couldn't break down a desperate tackling effort led by captain DJ Forbes.
The outcome leaves New Zealand (99 points) and South Africa (97) contesting a two-horse race for the series crown.
Third-placed Fiji (73) beat England (68) 14-7 courtesy of a late try in the playoff for third place.
Australia, climbed one place to fifth overall (59 points) after also scoring a try after the hooter to Ed Jenkins to head off Canada 12-10 in the Plate final.
The sixth leg of the series is in Tokyo on March 22-23.
