Perenara, a player with a more powerful running game than Smith, has worked hard on his passing, especially in the off-season - and the results are clear to see - but being in the same team as Smith, as well as Tawera Kerr-Barlow, is nothing but good for the Hurricanes halfback.

"It's very good," Perenara said. "He [Smith] is obviously a very good passer of the ball and having that competitiveness we both share - with Tawera as well - just trying to be better than each other and better ourselves day to day... it's good to have people there with quality in their skillset and are just as competitive."
He added: "Day to day and year to year I'd like to be improving my game. A big part of our team [Hurricanes'] success this year was up front we did a very good job and that allowed our backs to play better footy. A skillset for a halfback is key and that [passing] is something I worked on a lot in the off season.
"Throughout my career passing has been a big work-on for me. I played a lot of footy out of position [first-five] growing up and running was a part of the game I enjoyed and probably passing wasn't a part of the game I enjoyed so much."
As much as he downplayed it in London today ahead of the All Blacks' first game of the World Cup in just over a week, a big part of the Huricanes' journey to the final this year was down to Perenara's work behind the scrum. His passing game continues to be a focus, just as it is with any halfback, but it's no longer a weakness - his own hard work in toiling for hours by himself in the summer, plus the work he, Smith and Kerr-Barlow, do together has seen to that.
There can be comfort in hard work and there is a feeling among all the team in London that proper rugby training can't come soon enough, but as they continue to settle into the capital and recover from their long haul flight, mixing with the numerous supporters here has its own rewards.
Fans flocked to a promotion on the south bank of the Thames today and Perenara was left in no doubt as to their levels of enthusiasm at seeing the team.
"They're pretty excited about the challenge we have ahead of us and they take it on their shoulders to play as much of a part as we do so it's awesome to have that support over here."
Asked if any senior players had talked to him about the World Cup experience, Perenara, who has yet to play in one, said: "As a group we've never done something like this before so we've talked about the uniqueness of this World Cup and the uniqueness of this team. We have a challenge in front of us that we want to achieve as a team but ... we've just talked about taking one game at a time.
"Things are different. Teams are here obviously for one common goal and that's striving to be there at the end. You can't get too caught up with what's happening two or three weeks down the track."
