His confidence is high, he knows what he has to do to best benefit the team and his execution in those key roles has improved markedly.
Yeah, yeah ... I hear them; Steve Hansen and Ian Foster in unison saying "how many times do we have to tell you Nige, we don't make changes for changes sake".
Well in addition to the "we don't make changes for changes sake" line gentleman, you're pretty fond of "we know what this bloke can do, but we also need to find out if the other blokes can do it too" and you've also collectively spoken about managing workloads in the last fortnight.
Starting Perenara satisfies the first statement because it matches the second as well as the third given Aaron Smith has played a heck of a lot of rugby this season.
He's started all sixteen of his games for the Highlanders, missing only the round 15 clash with the lowly Southern Kings in Port Elizabeth, and averaging 75 minutes per game. (NB - Perenara played all 18 games for the 'Canes at a slightly lower average 71 minutes per outing)
However during the seven All Black internationals this season, all of which he has started; Smith's played an average of 64 minutes per test, while Peranara has played 105 minutes in six tests; under a quarter of Smith's 448 minutes spent on the field.
By the way, I'm not suggesting giving Aaron Smith the week off either.
He clearly possesses the most extraordinarily reservoir of energy and enthusiasm.
So how good would it be have him come hissing off the bench with 25 to 30 to go in Buenos Aires this Sunday morning?
It's not a bad option to have "the best half back in the world" - your words again Steve not mine (though I completely agree with them) - as the back-up.
The other benefit to starting Perenara in tandem with Hurricanes co-hort Beauden Barrett this week would be the selectors could either rest Barrett or use him off the bench next week in Durban whilst pairing up Aaron Smith with his Highlanders running mate Lima Sopoaga.
That's because sometimes "it's about combinations".
You can make cases for giving plenty of incumbents a week off and looking at the next option but for mine, the Smith/Perenara swap is the most compelling of all of them.
