Crockett replaces Tony Woodcock who suffered a rib injury in Sydney last weekend.
Coach Steve Hansen said that while the All Blacks had been happy with their opening 27-19 win it was expected they would continue to seek an improvement in their performance, which they were also anticipating from Australia.
"Playing in front of our home crowd is always exciting for the All Blacks," Hansen said.
"The fans are important to us and getting the opportunity to play a home Test is one we cherish."
The match kicks off at 8.35am BST on Saturday.
Hansen also announced that Charlie Faumuina, Tamati Ellison and Adam Thomson would be released to play for their provinces in the opening round of the ITM Cup.
