While no-one suffered serious injuries in the tense 16-14 win over England at Forsyth Barr Stadium on Saturday night, Thomas Leuluai and Tohu Harris both picked up ''shoulder complaints'', coach Stephen Kearney said.
Leuluai and winger Jason Nightingale also picked up nasty head injuries during the match. However, both passed fitness tests and were able to return to the action.
The Kiwis, who beat Australia 16-12 in the 2010 Four Nations final in Brisbane, have a golden opportunity to avenge last year's humiliating 34-2 loss in the World Cup final this Saturday.
With few international league tests played each year, Kearney is savouring the opportunity to play the decider in front of a home crowd.
''To get an opportunity to play in a final in front of our people will be fantastic,'' he said.
''Our focus is making sure we get ourselves recovered well. We will just prepare the way we have the last three weeks and get ready for the big one.''
The team will also be looking to improve its execution after chances went astray on Saturday night, including Vatuvei and Jason Nightingale dropping the ball near the line, Kearney said.
While the Kiwis are unbeaten heading into the final, they were far from convincing in the two-point wins over Samoa and England.
''We probably haven't played our best footy at times, but at the crucial moments when we need to, we seem to be pulling together and coming up with the right plays,'' captain Simon Mannering said.
The Kiwis thumped the Kangaroos 30-12 in the opening round but that result was meaningless ahead of the final, he said.
''Our focus isn't on what has happened before - it's what we can do throughout the week and what we can put on the field on Saturday night.''
Nightingale, who bagged a double on Saturday night, including a leaping grab via a Shaun Johnson kick, was looking forward to finishing the long season with a chance to hoist the trophy.
''We will take a lot of confidence in the way we have played in the last three weeks,'' Nightingale said.
''We have faced a lot of difficult challenges. We have been tested a lot along the way. I think we are prepared as much as we can for the final.''
The Kiwis arrived in Wellington yesterday to begin preparing for the final.
