Tokyo Olympics: Black Ferns Sevens open Games campaign with comfortable victory over minnows Kenya

Pre-tournament favourites New Zealand flexed their muscles with a comprehensive victory in their opening match in the women's competition of the Olympic Rugby Sevens.

The Black Ferns cruised to a 29-7 victory over physical Kenya in Pool A, with Michaela Blyde scoring twice in a slick performance to open their campaign.

Portia Woodman, Gayle Broughton and Stacey Fluhler also dotted down for the Kiwis. 

Meanwhile, defending champions Australia ran in eight tries as they defeated hosts Japan 48-0 in Pool C, with Emma Tonegato scoring a hat-trick. 

Great Britain survived an almighty scare when captain Abbie Brown scored a try after the hooter at the end of the game to secure a 14-12 victory over ROC (Russian Olympic Committee), and France defeated Fiji 12-5 in a tight opening match in the group.

The teams will be back in action with a second round of pool matches later on Thursday, with New Zealand playing Great Britain at 8pm.
