It completed a successful weekend for the New Zealand Sevens game as both the men's and women's sides won the titles, a repeat of their recent efforts at the Commonwealth Games on the Gold Coast.
QUICK TAP: BLACK FERNS SEVENS MAKE HISTORY IN SAN FRANCISCO
It was the third time the men had won the world title after they first claimed it in Argentina in 2001.
Scott Curry was named the player of the final while Joe Ravouvou was named the player of the tournament.
Again, it was their set piece dominance that proved the key to the win. But against England it was their lineout success, twice stealing England throws, to claim tries. Earlier, in their semifinal win over Fiji it had been from the scrums that New Zealand launched their winning assault.
Sione Molia scored the first from a lineout when beating two English tackles.
Then after England were pressured into throwing a forward pass in their own 22m area, New Zealand won the scrum and took the play to a goalline ruck when Tim Mikkelson was grounded just short. But Molia, at halfback, grabbed the ball and put it on the goalline for the try.
England came back with a well-constructed try for Mike Ellery to go to the break 7-14 down.

England struck again, this time by running the ball from the restart for Ruaridh McConnochie to get over wide out.
But from the restart substitute Trael Joass provided the set up work and Akuila Rokolisoa did the finishing to put the issue beyond doubt. There was only time for another restart but that gave Joass the chance to beat the defence again for the final try, 1m 41s into injury time.
Veteran Tim Mikkelson, who was player of the tournament at the last World Cup, said the win was massive.
"We knew coming it in was going to be tough, We nearly got knocked out by France but raised it against Fiji. Credit to the coaching staff, coach Clark Laidlaw is big on culture and he brought the guys together. The women put the pressure on us by winning their final.
It was the try that delivered @AllBlacks7s consecutive Rugby World Cup Sevens titles, but will this score from Trael Joass be your @DHLRugby Moment That Delivers for day three of Rugby World Cup Sevens? #RWC7s pic.twitter.com/kfOtqa5zXR— Rugby World Cup Sevens (@WorldRugby7s) July 23, 2018"But credit to England. They are an amazing team and they played some amazing rugby this weekend, we're humbled to get the victory," he said.
Curry said he was proud of the side's effort.
"We had four really tough games and credit to England. But I'm so proud of the boys.
"We have been working really hard for each other on the field and working hard off the ball and I think that showed," he said.
England qualified for the final by knocking over South Africa 29-7 and New Zealand followed with a 22-17 win over Fiji.
South Africa won the playoff for third place by beating Fiji 24-19.
