Savea, one of three changes made by head coach Steve Hansen to the side that crushed South Africa 57-15 in Durban, replaced Waisake Naholo who drops out of the squad.
Aaron Cruden, who is making his comeback from a groin injury, was named on the bench in place of Lima Sopoaga and Malakai Fekitoa was preferred to centre George Moala among the replacements.
"The squad is feeling refreshed and raring to go after our return from South Africa, and we're all looking forward to what we know is a hugely-anticipated test match at Eden Park," Hansen said in a New Zealand Rugby Union statement.
