Rugby Sevens: Tabletopping Black Ferns, All Black Sevens open account at Hong Kong world series stopover

World Series leaders New Zealand have shown little mercy towards women debutants Hong Kong China, pounding the home team 50-0 in their opening pool game at the Hong Kong Sevens.

Speedster Stacey Waaka grabbed a first-half try double, the first within the opening minute, and grabbed a third after the interval, as the Black Ferns Sevens extended their winning run to 25 games, since they lost the Dubai final to Australia last December.

Veteran Portia Woodman-Wickliffe added a try double to her growing record, while Hong Kong China were unable to trouble the tryline in their first appearance at this level. 

Later in the evening, New Zealand were almost as dominate against Great Britain, prevailing 43-0 to clinch a spot in the quarter-finals, with Shiray Kaka and Risi Pour-Lane scoring try doubles.

They face Canada to complete poolplay on Saturday.

After a three-year absence from the world series during the COVID-19 pandemic, the Hong Kong tournament has been expanded to feature a women's world series event for the first time.

Meanwhile, teenage rookie Cody Vai had his first try on the circuit, as the All Blacks Sevens have accounted for Kenya 29-5 in their opening match.

"Just amazing," said Vai. "I'm very surprised to be here, but still happy.

"Coaches have trusted me in this process and thanks to them as well."

Series tryscoring leader Akuila Rokolisoa added two more to his tally, as the Kiwis kept their rivals scoreless over the second half, after leading 19-5 at the break.

They take on South Africa and Ireland on Saturday in poolplay.
