The Black Ferns Sevens played South Africa, who were taking part by invitation, 40-0.

Tyla Nathan-Wong, Shiray Kaka and Gayle Broughton also scored tries.
A feature of the women's day was Fiji's upset win over Russia. Fiji had raced out to a 12-0 lead only for Russia to come back to lead 19-12. However, a strong second half saw Fiji win 38-19.
In other results, Australia was too strong for England winning 32-0, the USA beat Ireland 38-0, France beat Spain 36-12 and Canada beat Brazil 32-0.

Andrew Knewstubb sold a big dummy to the Welsh defenders to open New Zealand's scoring. Wales responded immediately but then the All Blacks Sevens went into overdrive as Regan Ware, Joe Webber, Tim Mikkelson, Akuila Rokolisoa (two) and Ngarohi McGarvey-Black all cross for tries.
New Zealand play Canada at 12.07 on Sunday morning and Argentina at 6.05am on Sunday.
