Sevens: All Blacks, Black Ferns untroubled in Cape Town openers

New Zealand have cruised through the opening day of the Cape Town Sevens, with both men and women scoring big wins in their opening pool games.

The All Blacks Sevens were way too good for Wales, running out 43-7 winners in the tournament opener.

After five minutes, the Welsh were on even terms at 7-7, but conceded six unanswered tries - including two to second-half replacement Akuila Rokolisoa - as the contest became a rout.

The NZ men face Canada at 12:07am Sunday (NZ time) and wrap up their pool scheduled against Argentina at 6:05am. The Argentinians accounted for their North American rivals 33-21 in their only outing of the day.

In other men's pool games, Fiji bounced back from their early exit in Dubai to trounce United States 28-14, Kenya toppled Samoa 24-19, while Scotland scored in the final seconds to edge England 26-24.

New Zealand would cross over with the pool containing Scotland, England, France and Spain in quarterfinals.

Meanwhile, the Black Ferns began their title defence with a 40-0 romp over hosts South Africa, who are not yet regular participants on the IRB World Series.

Alena Saili scored a brace of tries, with Tyla Nathan-Wong, Shiray Kaka, Gayle Broughton and Mahina Paul also crossing.

The NZ women take on Fiji at 9:35pm Saturday (NZ time) and complete their pool schedule against Russia at 3:25am.

The Fijians prevailed 38-19 over Russia in their tournament opener, while Australia, USA, France and Canada also tasted victory.
