There will be celebration on and off the field in Hamilton this afternoon.

The Kiwis will be facing Tonga at the FMG Stadium as part of Rugby League World Cup, and spectators are expected to flock in.

The Business Association in Hamilton have found a unique way to celebrate the two cultures coming together.

An Island Celebration is being held before the match at Garden Place on Victoria Street today.

General Manager at the Hamilton Central Business Association Vanessa Williams said they are hoping hundreds of people will turn up - as long as the weather plays fair.

Williams said it is everything you would want leading up to a World Cup game.

"Well we've got everybody from Kapa Haka groups, Tongan dancing groups, Russian dancing groups, singing groups. We've even got Moana the Pacific Princess coming down."

Williams hopes that hundreds will turn out to show their support of the event.

"We want it to be recognised as wide as it can be. So having something in the central city before down at the stadium just seemed like a really good way to support."

There will be an extra police presence on the Hamilton streets tomorrow after violent celebrations erupted following games last weekend.
