Pocock is relishing the prospect of one last opportunity to take on 34-year-old McCaw, who is considered one of - if not the - best number seven in the history of the game.

"He's a player who's been at the top of his game for a long time and he's someone who's proven that he can perform to that level over lots and lots of Tests," he told reporters on Tuesday.

"So it's always a challenge and I'm really looking forward to it."
