Kiwis assistant coach Adam Blair urged New Zealand to empty the tank against Australia in the World Cup final.
The former 51-Test Kiwi said it was the season's final game for many players, after about 30 weekends of physical commitment.
"You don't want to come off the field thinking 'what if?' You want to leave everything on the field that you have in the tank, put your body on the line for your brothers and do whatever it takes to win this game."
Blair said giving their best individually and collectively would make the team's effort satisfying, with a win worth celebrating.
He called the opening loss to Australia "most probably one that got away", but said a victory would still have prompted review.
The Kiwis should return to what works, make small improvements and build momentum, he said.
"This game is won on defence," Blair explained.
