The All Blacks are back in Auckland without two loose forwards who'll be in Christchurch with team doctor Deb Robinson to have injuries scanned.
The first choice number eight Kieran Read has a high ankle strain and backup flanker Adam Thomson an elbow injury.
Read lasted only eight minutes in Brisbane, where Australia won 25-20 to claim the Tri-Nations for the first time in 10 years, and Thomson went off late in the first half.
Head coach Graham Henry says Thomson's injury doesn't look good but he's more optimistic about Read's chances of playing in the World Cup.
And while admitting that the experiment of taking an understrength team to South Africa and bringing rested players to Brisbane didn't gel, Henry says there's no blueprint that says winning a Tri-Nations is the recipe for winning a World Cup
New Zealand won the Tri-Nations in 1999, 2003 and 2007 but then made premature exits from the World Cup and Henry says if there was any complacency in his squad, there isn't now.
