Wales proved New Zealand's nemesis once again, knocking the No.1 seeds out of the rugby World Cup Sevens in the quarter-finals in Dubai on Saturday.

The fired-up Welsh, who upset New Zealand at the Wellington tournament last month, won a pulsating match 15-14.

Zar Lawrence got New Zealand off to a flying start with a try in the first minute, but Wales hit straight back through the elusive Lee Williams who took the ball from the back of a breakdown deep in the New Zealand half and darted down the wing to score.

Wales kept New Zealand pinned in their own half for the rest of the first spell and went into a 10-7 halftime lead when Richie Pugh dotted down in the last act before the break.

The game see-sawed back in New Zealand's favour when Viliam Waqaseduadua beat two defenders to set up Lote Raikabula for a try. But then Waqaseduadua butchered another scoring chance, when with the line at his mercy he spilled the ball forward.

The mistake put Wales back on the offensive and a sweeping movement upfield ended with Tom Isaacs toeing the ball forward and scoring the winning try.

Australia's men failed to progress to the quarter-finals, finishing second to Samoa in their group.
