Hometown hero Lima Sopoaga is yet to play his second Test for the All Blacks, however an injury to Aaron Cruden last night could mean the Highlanders first-give gets a nod.
New All Blacks Damian McKenzie and Elliot Dixon are also eager to get their international careers underway.
"You gotta find out about them, and the best way to find out about them is to chuck them in," Fox said.
"A few tweaks, yes. But there certainly won't be wholesale changes."
A start for McKenzie is highly unlikely considering the return to form of Israel Dagg, who scored the opening try in his 50th Test last night.
Fox said Dagg's energy in the dressing room before the game was infectious and his performance was superb.
"I thought he was excellent," Fox said.
"All the boys in the dressing room afterwards were really pleased for him."
