The team's only current Black Fern, the Spirit No8 and captain has had another standout season and is ``fizzing'' before today's Farah Palmer Cup Championship final against Bay of Plenty in Tauranga.
The season has been a successful one for the team and it comes into the final on the back of a 39-12 win in last week's semifinal against North Harbour.
Despite a loss in its previous meeting against Bay of Plenty, Sisifa is confident the Spirit is capable of lifting the trophy this afternoon.
That confidence has the team riding high and, while plenty has been achieved regardless of today's result, it is a game she knows the team could win.
``I think there's two parts to it,'' the 27-year-old said.
``Win or lose we have had a really successful year just with the growth and the learning of the girls.
``Just being able to be a bit more professional with the way they come to trainings and come to games, I think we've moved mountains in that respect.
``But also I know that we can win this.
``On its own that's a separate entity in itself.
``It'd be a success to win this because everyone knows that we can as a group and everyone believes that we can do it and we've got the goods to do it.''
Discipline had been a problem in the loss to Bay of Plenty and she said the side had been working on that.
If it could keep that in check, as well as execute its game plan, she felt it was capable of getting a win.
Originally from New Plymouth, Sisifa arrived in Dunedin in 2008 to complete a physical education degree at the University of Otago.
Despite that, it was not until 2011 that the Spirit was able to call on her services, as she recovered from ACL surgery in her first two years, while there was no women's NPC in 2010.
She has more than made up for lost time since then though, staying in the South after finishing her degree and working with disabled children as a support worker.
Rugby had been a big part of that decision to stay and she said the Spirit had been a good stepping stone to the Black Ferns.
A skilful loose forward who is dangerous in the open field as well as getting through plenty of work and bringing physicality in closer, she has since earned seven caps for the national team.
While that enabled her to offer suggestions for different ways to do things, she said the biggest key to the side's success was its attitude.
``Mostly, I'm just impressed with the professionalism at trainings and games, the commitment the girls have put in.
``You don't need international experience for that; it's just whether you've bought into the team or not.
``It's taken probably the last three or four years, it's got better and better and this year has been the best from what I've experienced.
``So I think step by step everyone's gotten better by the year.''
