In a repeat of the 2013 final in Moscow, which New Zealand won 33-0, the Kiwis got the perfect start.

Sione Molia broke through two England tackles to sprint 40m to the line in the second minute. Kurt Baker's conversion gave New Zealand a 7-0 lead.

Molia grabbed his second try when he flopped over from a ruck after more concerted pressure by New Zealand, who had a penalty advantage.

Baker's conversion gave them a 14-0 lead.

England did not get over the halfway line until the final minute of the first half.

Mikkelson stopped their momentum with a spot tackle on Dan Norton, but the English kept the ball alive to allow Mike Ellery to cross for their first try.

Captain Tom Mitchell's conversion cut the halftime lead to 14-7.

England began brightly in the second half but blew it by conceding a penalty for holding onto the ball at a breakdown under pressure from Baker.

That gave New Zealand the field territory needed for Joe Ravouvou to race over for his sixth try of the tournament after beating his man and showing deft footwork to stay infield as he hurtled down the left-hand sideline to give the Kiwis a 19-7 lead.

That margin proved shortlived.

Burly Ruaridh McConnochie swatted away a Kiwi tackler to power over for a try down England's left edge.But Mitchell could not convert, leaving England trailing 19-12.

New Zealand substitute Akuila Rokoliso sealed victory with a breakaway try in the final minute, allowing Baker to add the extras and Trael Joass completed the rout in added time.

Veteran Scott Curry, who had a terrific game on defence, was adjudged player of the final.

Rouvovou, who finished as joint top-try scorer, won the Mark of Excellence award for the tournament's most influential player.

South Africa beat Fiji 24-19 in the third-fourth playoff to claim their first World Cup bronze medal.

SEMIFINAL WIN

New Zealand beat two-time champions Fiji 22-17 in the semifinal.

They started strongly with an early try to Ravouvou.

But Fiji struck back through former NRL rugby league star Semi Radrada.

Fiji were penalised for a ruck offence, allowing New Zealand to spread the ball wide for Dylan Collier to score his first try of the tournament.

The Fijians went ahead 12-10 with a controversial try after the match officials ruled Amenoni Nasilasila's heel was not in touch after a desperation tackle by Collier.

But New Zealand scored the all-important first try of the second half through Regan Ware, who sped 60m past Radrada for a 15-12 lead after a superb wide pass from Mikkelson.

Collier made a crucial tackle to snuff out a dangerous Fijian attack.

Ravouvou put the result beyond doubt with his second try with just two minutes remaining after a brilliant offload by Jona Nareki.

The Kiwis shut out Fiji with disciplined defence until the Fijians added a late consolation try to Alosio Naduva.

England, seeking their first World Cup win since the inaugural tournament in 1993, trailed after a converted try to South Africa's Selvyn Davids.

But, inspired by captain Tom Mitchell, they ran in five unanswered tries to make their second successive final.
