"There's a bit of nerves and George and the three are probably nervous. We saw it yesterday at training as we put quite a bit of pressure on the players with a high intensity training run."
Moala's earned his spot with his performances for the Blues and it comes after a season where he's been dealing with his own issues off the field.
"I told my mum and mum started tearing up on the phone. It's a great moment for me and my family.
"Obviously I've been through a lot on the last couple of years but I've left that in the past. I've put my head down and worked hard to be where I am today.
"Coming in and seeing the environment with how the players work as a team, it really helps you. It's more professional and I've really enjoyed it.
"I'm really really excited for the opportunity from Steve Hansen. I'm very grateful. To wear the black jersey is really exciting and I can't wait to get out there and do the task.
"There was a bit of nerves at the start but Steve Hansen and the other coaches and players have really helped me along the way to get me updated with everything."
Moala has impressed the All Blacks coaching staff in training and he said he was prepared for the physical test the Samoans will pose.
Hansen added: "He's adapted quickly and fitted in. He's comfortable on the ball and with the things we need him to do. It's going to be a big test and we need people to be comfortable."
