A major boost for the All Blacks Sevens in their quest to win the World Series' end-of-season championship next weekend in Madrid

Akuila Rokolisoa is back after missing three tournaments, while Scott Curry, Sam Dickson and Joe Webber also return from injury.

The Black Ferns Sevens welcome back Tenika Willison, who replaces Shiray Kaka... whose Olympics hopes have been dashed after an ACL injury in Singapore.

Former Wallabies captain Michael Hooper's Olympics dream could be over too... he's been left out of the Australian men's squad for the Madrid tournament.

Hooper will now have to overcome various niggling injuries and prove himself in training, if he's to make the final cut for the Paris Games.
