Captain Sergio Parisse, full-back Andrew Masi and Tommaso Benvenuti all played in the 32-6 loss to Australia.
Benvenuti, though, will switch from wing to outside centre for Tuesday's match against the Bears in Nelson - with Mallett full of praise of the 20-year-old.
"He is our fastest player and is as comfortable in the centres as he is on the wing," Mallett said.
"He has played there a lot for Treviso, notably against Leicester and Perpignan, and knows what to do there. He is important to our decision-making."
