Rugby Sevens: Payton Spencer scores twice on All Blacks Sevens debut at Sydney

Payton Spencer needed just three minutes to score on his All Blacks Sevens debut, showing his electric pace with a try-double in New Zealand's 45-7 win over Uruguay at Sydney.

Spencer, son of former All Blacks first-five Carlos, was handed a run-on debut after being named in Clare Laidlaw's squad for the Australian leg of the world series.

He wasted no time introducing himself, touching down inside the opening minutes with a brilliant break from the halfway line.

Che Clarke, Sam Dickson, Leroy Carter and Brady Rush all crossed for five-pointers, before Spencer grabbed his double shortly before fulltime.

After receiving the ball from a standing start just inside the Uruguay half, Spencer stepped his opposite, before beating him with strength and pace to score his second.

Akuila Rokolisoa scored after the hooter to give the All Blacks a resounding first-up win in Pool B, before they play South Africa and Kenya on day two.

Meanwhile, the Black Ferns Sevens have also made a perfect start at Sydney, as they chase their third straight title following their triumph at Hamilton last week.

New Zealand kicked-off their campaign with a dominant win over invitational side Papua New Guinea to sit atop Pool A after day one.

Tyla Nathan-Wong grabbed two tries, with six of her teammates also getting on the scoresheet, as the Black Ferns ran out 48-0 winners over the rugby sevens newcomers.

Try-scorer Jorja Miller praised the veterans in the side, and the returning Black Ferns from their World Cup triumph last year.

"It's pretty amazing, obviously growing up, all these legends are who you watch and [now] standing on the field beside them - it's a pretty cool feeling," she told Sky Sport post-match.

"So much, they bring so much knowledge from fifteens and experience and just little things we can implement into our game and take us to that next step, which is awesome.

"Just looking to go have fun with the girls, do my job and hopefully everything falls into place from there.

The Black Ferns Sevens will play France later on Friday, before tackling Japan on day two to determine the quarter-final matches.
