Naivalu doubtful for Bledisloe Cup opener
Naivalu suffered an ankle injury in the 40-29 win against Italy and will be out for up to seven weeks.
Meanwhile, Wallabies captain Stephen Moore lashed Super Rugby franchises for not preparing players for the rigours of Test rugby.
Moore has backed Michael Cheika's comments throughout the June Test series, saying players simply weren't fit enough for the international arena.
"It shouldn't be hard for Super Rugby to produce players that are ready for Test match footy," Moore said.
"I don't know what the issue is there, but we need to make sure the next two months or whatever it is … we can't waste a day.
"There is a gap between Super Rugby and Test rugby, the intensity's up, but that doesn't mean we can't train like we have to play Test footy."
Despite the Wallabies average performances in June, Cheika said he was confident they can pull off a major shock against a team (New Zealand) that beat the British and Irish Lions 30-15 in Auckland on Saturday.
"I know everyone's having a laugh when I say that, but I believe with that clear goal we can go there and do that," he said.
"We've got to work extra hard and we've got to be prepared to work even harder once we come out of Super Rugby for that little [training] block to be ready because it's a key element to staying in the game."
