"We get the feedback from all the other players from the other countries and this is the tournament that they always want to play, so it's awesome."
New Zealand have a healthy lead in the series standings after three legs and victory this weekend would put them on the right track towards another world title.
They're in Pool A with England, the US and Spain and Raikabula said the English, who New Zealand meet first today, would be a huge threat after a disappointing start to the world series where they sit 13th.
"They'll try to get back on the horse at this tournament so we know it's going to be tough," Raikabula said. "We are not looking ahead of the second and third game so we are looking forward to the England game."
The US are a rising power in the sevens game and boast the quickest man on the circuit in Carlin Isles, and Spain are rank outsiders.
Aside from their newcomers to Wellington, New Zealand's squad offers experience in Raikabula, skipper DJ Forbes, pivot Tomasi Cama, Waikato's Tim Mikkelson and Crusaders' outside back Kurt Baker.
France and Kenya open the tournament at 1pm today with the finals tomorrow.
