Greg Eastwood could play for all but one of the teams in the Four Nations series but will leave no doubt over his allegiance when he faces England at the Galpharm Stadium on Saturday.

The 22-year-old back row forward was a member of New Zealand's World Cup-winning team last November and will be leading from the front as the Kiwis bid to reach the Four Nations final at England's expense.

A proud Kiwi, Eastwood's pasty complexion gives away his English heritage and defies a decade spent in Australia's sunshine state of Queensland.

Eastwood is preparing to set up home in his father's native country after signing a three-year contract with Super League champions Leeds Rhinos and will this week pay a trip to Huddersfield, venue for Saturday's crunch match, to update his family tree.

"My father was born in Huddersfield," he says. "All his family moved to New Zealand when he was 13 but there are still a few relatives here.

"They've been on Facebook to make sure I go and visit them. It will be good to see my dad's side of the family."

Eastwood, who was born in Auckland to a Kiwi mother, moved to Brisbane as a youngster and made his name playing for the Broncos but cherishes his New Zealand roots.

There will, therefore, be no quarter asked or given when he comes up against his new club captain Kevin Sinfield and up to four more of his prospective team-mates in Saturday's do-or-die clash.

"Kevin's our club captain but he won't take it easy on me, so I'm not going to hold anything back," he says.

"I'm getting ready for a battle. I might have a few words with them after the match but it's war on the field when you're playing for your country.

"It's exciting. This will be a big one for us. I want to do my country proud."

Eastwood's signing for the Rhinos - as a replacement for Gareth Ellis - was announced more than a year ago but the move was put in jeopardy when he was refused a visa due to speeding convictions.

The Broncos had no room left on the salary cap but Canterbury Bulldogs came to his rescue and he enjoyed a successful season under NRL coach of the year Kevin Moore.

He remained committed to Leeds, however, and, after winning his appeal against his visa rejection earlier this year, he is looking forward to finally getting the chance to ply his trade in Super League.

"It was a bit frustrating last year but I'm looking forward to it now," he says. "I can't wait to get over and start with a new club.

"Bluey (Leeds coach Brian McClennan) was calling me every fortnight to see how I was going and tell me what they're doing.

"It was good to keep in touch and I watched a few of their games. They did well this year, I'm happy to be at a good club."

Eastwood will return to Brisbane at the end of the Four Nations but does not anticipate experiencing the difficulties that have hit so many overseas players' plans to come to England.

"I've got my passport with my visa in it so I think I'm secure," he says.

"I'll go back to Aussie for a bit and then come back just before Christmas with my partner.

"I'll say goodbye to my mum and dad, I probably won't see them for a year or two.

"It is a bit daunting but I've got (New Zealand team-mate) Thomas (Leuluai) here, he says I can go visit him any time I want if I get homesick."
