Fiji captain Osea Kolinisau is hoping his team can begin 2015 with a win at round four of the HSBC Sevens World Series in Wellington.

Having won the opening tournament in Australia, Kolinisau and his side have seen South Africa win rounds two and three in Dubai and Port Elizbaeth to sit on top of the standings as qualification for the Olympics heats up.

But with current sevens player of the year and leading try scorer last season Samisoni Viriviri returning to Ben Ryan's side, the Fiji captain believes his side have enough to win their second title of the season and their first in Wellington since 2010.

"We want to kick off our year in style with a win and try to catch up with South Africa," said the current leading points scorer this season Kolinisau.

"We were disappointed with our performances and let ourselves down in Dubai and Port Elizabeth but we know the biggest opponent is ourselves. We went away and worked on our mistakes in the break and now with the team we have we are confident we will have a good outing in Wellington.

"To have Sami (Viriviri) back in the team is a great boost as you can't buy that experience. His experience and extra pace out wide will be something we look to utilise this weekend."

WELLINGTON AND VEGAS IMPORTANT PART OF SERIES

With a third of the series already gone, and the top four teams qualifying automatically for Rio at the end of the ninth round in London, the next two tournaments are vital for those knocking on the door like Argentina and England to break into those spots, or those looking to cement their place at the top.

"These two tournaments are an important part of the series, especially with the Olympic qualification" added Kolinisau.

"We know we need points and there is an opportunity for us to stay in touch with or overtake South Africa in the series standings but also take a step closer to achieving qualification. Getting off to a winning start is important but so is the consistency to back it up in Las Vegas too."

Head coach Ben Ryan, who has made five changes to the side that competed in Port Elizabeth, where Fiji lost to USA in the Plate final, echoes Kolinsau's beliefs on the importance of rounds four and five.

"History shows that after these two tournaments there is not too much change with the standings and those after London, so our performances are important," said Ryan, who won the Wellington tournament with England in 2013.

"But we've a great team here and I'm looking forward to having some fun this weekend and looking to challenge South Africa, a side we're yet to meet."
