Kiwis coach Stephen Kearney says the Kangaroos being hit by a virus ahead of Saturday’s Four Nations rugby league final holds little relevance for New Zealand.

As many as five Kangaroos players have been quarantined as team officials strive to ensure a fully fit team for the decider against New Zealand at Wellington’s Westpac Stadium.

But Kearney says the Kiwis remain focused on their own build-up as they look to back up their upset 30-12 win over the Kangaroos in Brisbane three weeks ago.

“Our focus from the start of the tournament has been making sure our preparation is right, and it’s no different this week,” Kearney said.

“I’m sure they’ll be ready to play, whoever it is, but our focus is purely on us.”

Kangaroos coach Tim Sheens brushed aside concerns that his illness-hit team wouldn’t be ready for Saturday’s showdown, saying no one was in danger of missing the game.

The Kiwis completed a light training run on Wednesday morning, and although halfback Shaun Johnson pulled up early, Kearney had no concerns around his playmaker’s fitness.

“He just had a little bit of a tweak, which those prime athletes do sometimes, but he’s fine,” he said.

“The Ferraris you’ve got to look after a bit better – the old Volkswagens in the middle of the park, the forwards, they don’t need too much tinkering around with.”

Kearney said the Kiwis had long put their opening Four Nations win over the Kangaroos behind them and it was obvious the Australians had regrouped with strong performances in beating England and Samoa.

The New Zealanders have also refocused after being pushed hard by England in Dunedin last week, holding on for a 16-14 win.

“We’ve identified areas we need to improve on from last week’s game, and we’ve worked on those in the last couple of days,” Kearney said.

The Kiwis’ up-tempo play and ability to offload played a big part in the win over Australia, and Kearney is looking to build on that in Saturday’s final.

“We’ve focused on creating platforms for those opportunities to happen, and we want to be able to take that opportunity away from the opposition.

“It works both ways. Unless you’re laying a platform and building momentum, then those opportunities are pretty rare.”
