Rugby Sevens: NZ women keep Vancouver title hopes alive with semi-final win over France

Black Ferns Sevens have kept their quest for a fourth straight tournament victory alive, overcoming France for a spot in the final at the Vancouver world series event.

The NZ women will face archrivals Australia, after their dominant 36-7 win over the French in the semis.

Leading 17-0 at halftime, Michaela Blyde made the contest safe with a length-of-the-field try, converted by Tyla Nathan-Wong, immediately after the restart, before France pulled on back through Jade Ulutule.

Speedster Stacey Waaka grabbed her second try, before Jazmin Felix-Hotham broke through to put the seal on their performance.

New Zealand were almost upset by Canada in the quarter-finals, where they emerged 10-5 winners in a tense finish.

Meanwhile, the All Blacks Sevens have cemented a fifth-place finish, after a 50-7 demolition of United States.

After overwhelming them 52-0 in poolplay, the win was their second of the tournament against the Americans, with Joe Webber running in a hat-trick of tries.

Their hopes of a third consecutive tournament victory ended with defeat to Australia in the quarter-finals, but they bounced back against the British, with Roderick Solo scored a trying double en route to a 19-5 win.

Their lead atop the overall series standings has been reduced to 12 points over nearest rivals Argentina, who beat France 33-21 in the final.
