McCaw has called for a repeat in next week's final.
The All Blacks will return to Eden Park to take on France after a comprehensive 20-6 success against the Wallabies.
And McCaw said: "It was awesome, we realised we had to front up and be on the job for 80 minutes. Every single man did their bit, and that's what you've got to do in knockout rugby.
"We've got the job to do next week, but I'm pleased with how the guys fronted up. The intensity of the ball-carriers and at the breakdown was the key."
New Zealand also dominated the scrum and McCaw continued: "One to five have been around a long time, that's been building and it was a pretty good performance tonight, but we need it next week."
The superstar flanker has been nursing a foot injury throughout the tournament, but said: "I'll rest up again and be good to go next week, I'm sure."
Wing Cory Jane was named man of the match after facing up to an aerial buffeting which left him bloodied after a blow to the nose.
On the barrage of high kicks, he told ITV1: "It's my job to catch them, I'd have been in trouble if I'd dropped them.
"My beak took a bit of a battering, it was a hell of a Test match but it's good to get past the semi-final and look forward to a good week and the final."
Jane was joined by Israel Dagg - whose strong run created the only try for centre Ma'a Nonu - and Richard Kahui in a fine display from the All Blacks' back line, and said: "We talked about it during the week, we had to work well together and we managed to do that at times tonight.
"The boys can take confidence from what they've done tonight."
