So when Scott and Jordie were named on the All Blacks squad to tour Europe at the end of this year, it was an emotional reuniting for Beauden.
"It was just amazing," he told Newstalk ZB's Tony Veitch. "I hadn't spent that much time with those two since I was a kid growing up with them back in primary school.
"It was really special, and a good opportunity for me to get to know them."
While Beauden has made a home with the Hurricanes, and brought them their first Super Rugby title in 2016, his brothers ply their trade down in Canterbury - though Jordie will be joining his brother in Wellington next season.
The distance, and indeed the demands of a professional sporting career, makes keeping track a little more difficult, so seeing his brothers in the same dressing room made for something pretty extraordinary.
"Obviously they're down in Christchurch doing their thing, going through a lot of changes, they're growing up," Beauden said.
"So it was pretty cool."
But more than anything, Beauden was just happy to know his brothers were doing well and making something of their talents.
"To see Scott kick on in the way he did, I was really proud of him for that," he said.
"Also Jordie, the leaps and bounds he's made this year, I'm pretty excited for next year."
The thought of two Barrett brothers in one team is scary enough, but come next year's Lions tour, they could make up a fifth of the All Blacks starting 15.
