"I was dumbfounded by it a wee bit initially, the selection," Hansen said. "I thought, 'Why would he do that?' I came to the conclusion that maybe Ewen doesn't trust him [Foley] to be able to do what he wants against us. Or if you really think about it, the other guy [Beale] is under contract and league are chasing him so you might start to think maybe the ARU has told him he's got to pick him.
"At the end of the day it doesn't matter why he has. Both of them are very good rugby players and Kurtley is certainly a guy who loves to do things differently. He will throw a lot of inside balls to runners so we're going to have to make sure we look after that part of the park, particularly from second- and third-phase play when guys are struggling to get into position. He'll be dangerous.
"He's not as good a goalkicker as Foley but I guess he'll bring Foley on late in the game and if they need a goalkicker."
Asked if he would select a player if the New Zealand Rugby Union told him to, Hansen replied: "No."
Pressed on his "assertion" regarding McKenzie following orders, Hansen said it was an "assumption".
"One guy has played there all year, the other guy has played seven tests at most in his whole career at first-five, so why would you change that? It was just a thought that came through my head and I'm sure it came through a few other people's."
Asked if the All Blacks would try to rattle Beale, he said: "If we're going to win the game we're going to have to rattle a few of them better than they rattle us."
Warming to his task, Hansen added: "There's been a lot of talk [that] because they have won the Super Rugby they will win the Bledisloe Cup but that's rubbish. There's [no] correlation at all."
Hansen found it amusing that Australia were putting pressure on themselves by talking about this being "their year", in the wake of the Waratahs' triumph.
"I find that interesting. It's no different to any other year. There's two teams... one of them will win it and one of them will lose it."
Hansen said the decision to select Ben Smith at fullback ahead of Israel Dagg, a minor surprise of his own, was down to Smith's form, particularly on the counterattack. He said lock Patrick Tuipulotu was unavailable with a high ankle sprain and prop Charlie Faumuina had strep throat.
