Compounding his itchy feet must be the way relative newcomer Charles Piutau has taken his limited opportunities on the wing.
"It is bittersweet. It's awesome seeing the boys excel and take their opportunities and play the way they've been playing but as a footy player and athlete, you want to be playing every single game," Perenara says. "It doesn't matter which team you're in. But I wouldn't change it. I think the environment that I'm in, it's doing nothing but help me grow as a player and as a person. It's challenging.
"The way I look at it, the All Blacks are the best team in the world and it shouldn't be easy to play for them. You shouldn't be picked straight away, you should have to graft your way through. As hard as it is for me to not be playing, it is the best team in the world, they are the best two halfbacks in the world, and I've got to keep trying to be better than them. It's only a good thing for our country and our team.
"I've learned a lot actually, a lot about myself and a lot about footy. I guess not playing, I've learned a lot more about the game.
"I've played a lot of footy and not really thought about the game and the way the game is being played ... about, I guess, the fundamentals of rugby itself."
The willingness of the 21-year-old, a product of Porirua's Mana College, to push himself this season resulted in a stress fracture which he says was also valuable in a way.
"I was trying to push myself further and further ... it was a hard lesson to learn that sometimes I have to listen to my body and get my fitness in other ways."
Which brings us back to Perenara's running game. Seen as someone who will eventually overtake Smith and Kerr-Barlow due to the X-factor he brings to the position, he is not getting ahead of himself.
"It's probably one of the things that got me where I am but it's also a weakness. My core skills of passing and kicking are probably not as good as most other halfbacks.
"The higher you get in your footy, the better the opposition get and the better they can read you. If you don't have anything else, they shut down your running game and then your passing and kicking game is ineffective as well.
"It's one of the things I've been working on a lot over the past four or five months - my core roles of passing, kicking and decision-making. When I get the opportunity to run, that's when I have to take it ... I can't go into a game forcing it."
