Rugby World Cup: Sevens heartbreak fuelling Sarah Hirini's Black Ferns desire

Black Ferns Sevens captain Sarah Hirini has her eyes on World Cup redemption, after heartbreak in South Africa just over a week ago.

New Zealand were stunned by Australia 24-22 in the final of the Sevens World Cup final at Cape Town.

A self-confessed bad loser, Hirini has taken time away from social media to digest the agonising loss, but is now raring to go for the Black Ferns 15-a-side team.

With the World Cup beginning on October 8, the Black Ferns play Japan in a warm-up match at Eden Park on Saturday and Hirini has her sights firmly set on what's ahead.

"I think that's why I took a bit of time off social media, not to forget about it, but to know that it's there and move on," she said.

"I knew I had to move on quite quickly. I don't want to come into this environment and act like a sad sack, and bring whatever happened last week into it.

"I knew I had to come in here with a new energy and new excitement. I had to learn a lot and there's been a lot that I've had to know the last couple days and the test match this weekend.

"It's kind of move on pretty quickly and we've got something else to focus on."

Hirini is far from a newcomer to the 15s game, previously turning out for New Zealand at the 2017 World Cup, but she's made a name for herself in sevens, where she debuted in 2013 and is now regarded as one of the best players in the world.

She admits the transition back to the traditional format has been tough, but relishes the challenge and appreciates the support she's received from her teammates.

"I texted my husband this morning and said, 'It's been really nice to actually get up before training and learn stuff'," she said.

"I'm not saying I don't learn in sevens, but there's so much I have to know before Saturday and it's no excuse that I'm new, hich has been cool. I've had four girls come up to me and say, 'If you need anything, I'm here, if I can help with anything'.

"There's plenty of amazing people that I know are going to help me - I think even relearning the haka will be pretty scary as well."
