Quade Cooper will only "enhance" the Wallabies' chances after his shock selection at fly half for Saturday's second Bledisloe Cup Test in Wellington, All Blacks coach Steve Hansen says.

Cooper has been thrown into the number 10 jersey for his first match at international level since last year's World Cup, replacing Bernard Foley, who moves to inside centre to replace Matt Giteau (ankle).

The 28-year-old has a patchy record in New Zealand, where he has been booed mercilessly by local supporters and targeted by the All Blacks as a weak link in defence.

Squad Wallabies (15-1): Israel Folau; Adam Ashley-Cooper, Samu Kerevi, Bernard Foley, Dane Haylett-Petty; Quade Cooper, Will Genia; David Pocock, Michael Hooper, Scott Fardy; Adam Coleman, Kane Douglas; Sekope Kepu, Stephen Moore (capt), Scott Sio. Replacements: Tatafu Polota-Nau, James Slipper, Allan Ala'alatoa, Will Skelton, Dean Mumm, Nick Phipps, Tevita Kuridrani, Reece Hodge.

But Hansen offered something of a defence of Cooper when asked for his view of the selection.

"Quade's a good player. He gets maligned a wee bit over here because of a few incidents with Richie (McCaw)," Hansen told reporters.

"We're not too forgiving of people who pick on Rich — I'm talking about the fans.

"Within the team he's well respected. He'll enhance them, I think."

Hansen — who, along with McCaw, called for New Zealand fans to get over their hatred of Cooper last year — said he expected the Wallabies to look to kick more and play a territory game as a result of his selection.

All Blacks five-eighth Beauden Barrett hopes a sold-out Wellington Stadium takes it easy on Cooper.

"He's a good bloke and he deserves to be treated like anyone else," Barrett said.

"I haven't seen him play for a while but what we remember of him is his skills, his fast feet, he's a really good stepper. We'll analyse his kicking."

The Wallabies have not won in New Zealand since 2001 and are the biggest outsiders in Bledisloe Cup history this week, but Hansen is bracing for the "kitchen sink" to be thrown their way.

"If we don't have an attitude that we want to go and put two hands on the cup by taking it, if we wait and sit back, Australia will smack us," he said.

"Then we'll be in trouble."
