It is the start of a three-match series and another step on the journey to a World Cup defence, however, McCaw the focus had solely been on a one-off performance against Stuart Lancaster's men, the last team to beat the All Blacks when they stunned them at Twickenham at the end of 2012.
"We understand the challenge that's in front of us. Test footy is different to what we've been doing for the last two or three months so we're going to have to make sure we're quick to get up to speed with that and the intensity that comes from it," McCaw said.
He said the debutants in the team, Malakai Fekitoa and Patrick Tuipulotu, appeared quietly excited about the challenge ahead, with another "rookie", the returning Jerome Kaino, also maintaining a quiet intensity. McCaw said Kaino's form for the Blues on his return from Japan was no surprise to him.
"We all knew he was a classy player before he left. They must have taken it pretty easy on him in Japan - he's fresh and ready to go."
