McCaw: Bledisloe Cup not in the bag

But McCaw implored his side to learn from their mistakes in the June Steinlager Series against Ireland where they narrowly avoided defeat in the second Test.
Having won the opening Test against Ireland 42-10, the All Blacks had to rely on a Dan Carter drop goal in the 80th minute in Christchurch.
"I think history has shown when you play back-to-back Tests, if you don't get your preparation right you trip up," McCaw said.
"We had a lesson like that back when we played Ireland.
"If you don't prepare well and you just turn up expecting it to happen you'll come unstuck.
"So that's our challenge, to get past this game and work out ways that we can turn up and play better, because there's absolutely no doubt the Wallabies will do that."
Coach Steve Hansen added: "It's about going home, staying humble, keep our feet firmly on the ground and not too much back slapping and saying 'right we've got an opportunity here to keep it (the Bledisloe Cup) if we prepare well and make sure we do what we have to do in a genuine fashion'.
"And then if we front up on Saturday night with the right attitude well then we give ourselves plenty of opportunity to do that because we have quite a lot of talent in the team.
"But if we go home and think we've done the job already then that's a recipe for disaster."
But Hansen couldn't resist the chance to take a swipe at the Wallabies when asked if Saturday's loss was a psychological blow for arch rival Robbie Deans' side.
"I think it'll hurt them, no doubt about that," Hansen quipped.
"We've read all week about how they were going to do this and do that and they'll probably be disappointed that they didn't do this and do that."
Hansen concedes the All Blacks weren't at their clinical best in a clash that featured several uncharacteristic errors from both sides.
"It probably was not the most perfect game in the world but when you get two sides coming off the breaks that we've had and playing at the intensity we were playing you're going to get errors," Hansen said.
"I thought both sides hung in there and will both be better for the experience and next week we'll get a ripper of a game.
"So really pleased that we were able to get that win away from home and even more pleased to make sure they didn't get a point as far as the (Investec) Rugby Championship goes, and I thought we had some really good displays from our guys.
"If someone said to me we'd get three points on an away game we'd take it every time, the only thing you'd want more is maybe a bonus point, so we haven't done too bad."
Meanwhile, Hansen confirmed prop Tony Woodcock suffered rib damage in the physical encounter.
"He's got a sore rib, I don't know how bad it is yet," he said.
