Thomas Leuluai will send his Wigan team-mate Sam Tomkins a good-luck message before Saturday's Gillette Four Nations match - and then try to ruin his big day.

The Warriors half-back partners will be on opposite sides at Huddersfield's Galpharm Stadium when England take on New Zealand in the final Four Nations group match, with a place in the Elland Road final at stake.

Leuluai, who is being used by the Kiwis as a hooker, wished his club-mate the best of luck before England's match against Australia at Wigan's DW Stadium last Saturday and Tomkins responded with an impressive performance in their second-half fightback as they went down 26-16.

"I talked to him before the game and he was pretty confident," said the Kiwi. "I texted him in the week to see how he was doing and wish him good luck.

"I'll do the same this time. He's a good fella. Obviously I hope we win but I hope he has a good game too."

While England paid the price for a slow start against the Kangaroos, the Kiwis cruised to a 62-12 win over France in Toulouse and are favourites to set up a repeat of the World Cup final.

However, Leuluai is warning his team-mates to expect further improvement from England after they prevented Australia from scoring in the second half at Wigan.

"It was always going to come down to a do-or-die match with England," he said. "It's going to be a difficult game.

"They came back well in the second half against Australia so I suppose they'll take a lot of confidence from that.

"We played pretty good in the first match but started a bit slow against France.

"We've still got some improvement in us, which is a good thing. You don't want to be hitting your form too early. We've still got things to work on."

As the only Super League-based player in the Kiwis squad, Leuluai is perfectly placed to provide last-minute tips on the opposition but he reckons coach Stephen Kearney is already up to speed on the England side.

"Steve does his homework," said Leuluai. "He pretty much knows them all too.

"I'll jump in if there is anything I can add but he's covered pretty much all bases."

Speaking ahead of his side's final training session, Kearney said he has been impressed by the impact made by Tomkins so far in the competition.

"I think I've seen enough of him to know what he's about," he said. "I thought he had a great game against Australia.

"I know he's held in high regard - otherwise he wouldn't be in the squad at such a young age. He's obviously got something to offer the group."

Kearney has spent the last 24 hours studying video tape of England threequarters Peter Fox and Chris Bridge, who will get their first taste of Four Nations action tomorrow.

"Obviously they felt they needed to make those changes," he said. "Young Fox and Bridge are handy replacements to have going in there. I'm sure they will acquit themselves very well.

"I've been very impressed with the way some of those young outside backs of England have been playing. We know what's ahead of us."

The Kiwis' only change to their starting line-up is the addition of 19-year-old Kieran Foran in place of injured centre Steve Matai, and New Zealand captain Benji Marshall revealed today he has been pushing for the call-up.

"I've been one of his biggest supporters throughout this whole campaign," he said. "I've been willing for him to get a game.

"I trained with him in the off season and got to see a bit of him on tour. He's one of the most talented young players I've seen."
