Update: 1:54PM NEW Zealand wrapped up their 12th world series rugby sevens title in 15 years despite losing to England on the first day of the London sevens tournament at Twickenham.
The All Blacks Sevens needed only to qualify for the quarter-finals in London, the final leg of this season's series, to secure the overall title.
They are now assured of winning the nine-tournament competition, currently sitting at the top of the table with 158 points, ahead of South Africa (139) and Fiji (129).
New Zealand won their two opening pool matches, downing Wales 49-0 win and Argentina 40-10 but tripped up against England, who won the third pool A match 15-12 with a late penalty from skipper Tom Mitchell.
The All Blacks Sevens finish second in Pool A and will meet South Africa in the quarter-finals late on Sunday (NZT).
Evergreen playmaker Tomasi Cama returned to the All Blacks Sevens in the Argentina match, becoming the second player in the history of the tournament to score 2000 points when he converted Akira Ioane's second-half try.
New Zealand captain DJ Forbes said although it was pleasing to have the overall title wrapped up, losing to England in front of a record 75,000-strong crowd was disappointing.
"A few things didn't go our way - I think that was easily our game, but we left England off the hook," he said.
"But they played well, they played some smart rugby. We've joined the hard side of the draw, we're always facing the big guns.
"We've won the world series, but a bonus would be winning here in London to top it off."
