After both Pacific Islands sides lost their opening matches of the tournament, a defeat in east Yorkshire would seriously dent any hopes of progression from Group B.
He said, “Obviously we were a bit disappointed with the result against France but there are still a lot of positives to take out of that game.
“It means we go into training with a bit of confidence and we know the areas that we need to improve. For us it has been so far, so good.”
Also missing are stand-off Rene Maitua and new Bradford signing Frank Winterstein, who has undergone an operation that will keep him out for the rest of the tournament.
“It is really good over here,” said Taufua. “For a lot of us it is our first time in England and we are all really enjoying it.
“In a tournament like this, every game is like a semi-final and hopefully we can stay a bit longer than what a lot of people have had us down for.”
