New Zealand captain DJ Forbes says playing error-free rugby will be the key to his side’s chances at the Hong Kong Sevens this weekend.

New Zealand have their opening pool match against France tonight and face dangerous Kenya and the United States tomorrow.

Hong Kong remains the glamour event on the calendar and New Zealand enter three-day tournament with a handy lead in the World Series, 23 points clear of second-placed South Africa.

But New Zealand’s success this season has been more about consistency than spectacular play.

This is the sixth stop on the nine-tournament series and already there have been five different winners.

New Zealand, who won the South African leg, are eager for another title in Hong Kong but Forbes warns that this is the most difficult tournament t to win.

"The big teams definitely take it to another level here in Hong Kong," Forbes said.

“A lot of teams target this one and a lot of teams have brought back a few old faces.

“The series is getting more and more competitive and the last five winners are all going to put their hands up here. Anyone could win, it just takes a bounce of the ball.

“Everyone has seen how consistent we are .. we have been in a lot of finals this year.

"For us it is about error-free rugby and we are looking for title number two (of the season), and it would be pretty special to do it here in Hong Kong.

“But every team that meets us, whether it’s a pool match or a final, grow another leg.

“If we play error-free rugby we will be there or thereabouts.”

New Zealand lost last year’s Hong Kong final 35-21 to Fiji.

Brazil, who will host the 2016 Olympics where sevens will debut, are playing in Hong Kong for the first time. Brazil have New Zealanders Chris Neil and Dallas Seymour in their coaching team.
