Asked whether New Zealand's long list of excellent No 7s - Graham Mourie, Michael Jones, Josh Kronfeld, McCaw et al - compounded the pressure and expectation, Cane said: "You put your own expectations on yourself and there are high expectations in this All Black environment so nothing really changes."
Hansen said of Cane, who has played only nine tests: "He's ready. He's been around the environment for quite some time now.
"He's a good athlete [and] mentally he's able to put things in perspective... [which is] not an easy job coming in and following a guy like McCaw because you're compared to him all the time. He's just got to be his own man and do his own things that he does really well.
"How does he cope? We've got to do a job in the tight five and if we don't ... then their loose forwards as a trio will dominate."
Cane's Chiefs' teammate Liam Messam's return from a hamstring injury will add more of a defensive element to the pack, with No 8 and skipper Kieran Read a crucial element to the All Blacks in rounding out the home team's loose trio.
Cane recognises both the responsibility placed on his shoulders and the opportunity.
Having made his test debut against Ireland last year, he started all three tests against France in June when McCaw was having his sabbatical.
He said: "It's good to be starting. After a warm-up with the All Blacks and the atmosphere you're always ready to go anyway so it will be good not having to wait."
