New Zealand have regained their form after winning their first three matches at the women's World Rugby Sevens Series in Canada.

Today they got back on track with a 26-7 victory against Russia at Langford's Westhills Stadium.

In their remaining Pool B games, New Zealand thrashed China 45-0, before narrowly defeating England 12-10.

They will face Spain in the quarter-finals.

Australia are also on a winning run, comfortably taking victory in all their Pool A games.

They beat Ireland 33-5, Brazil 43-7 and Canada 29-14.

The United States were dominant in Pool C, easing past Spain 21-12 before defeating Fiji 28-7 and France 12-0.

Australia will play Russia while the US meet Canada.

The quarter-finals, semis and final are scheduled to take place tomorrow.
