Their music might be the soundtrack to many a Kiwi summer, but it's a big leap from that to becoming the first New Zealand band to headline Western Springs.
So did Six60 live up to the daunting task?
You bet they did.
In front of a sold-out, 50,000 strong crowd, the band produced a slick, energetic romp that showed they deserved their moment in the country's music history.
And from the moment they walked out on stage, you could tell how much it meant to them.
Lead singer Matiu Walters put his hand on his heart as he took in the roaring crowd, rolled his shoulders, took a deep breath, and then launched into the band's hit summer single, Vibes.
From there, it was all go.
But they clearly haven't forgotten their roots (sorry, it had to be done).
They paid homage to their Dunedin origins with images of their namesake Castle St flat on the big screens on either side of the stage.
They also turned the catwalk into a Scarfie flat-like setting for a few songs, complete with dodgy couches and slightly depressing beige lamps.
The nostalgia-heavy start to the show almost veered from sweet to overdone, but they pulled it back just in time, belting out some brand new tunes that already seem destined to be hits.
He's not a flashy frontman, but the gig proved Walters' voice was made for stadium shows.
His impressive range was on full display in songs like Purple, their first big hit Rise Up, and Lost.
Lost also provided one of the most memorable moments, as Walters made his way to a small stage in the middle of the crowd to belt out the ballad while tens of thousands of phone torches lit up the sky.
After Workman told the crowd at the start of the show it was "just Six60, and their choir of 50,000 strong", the band brought out an actual choir for their encore, including a rousing version of Mother's Eyes.
As they walked off stage to the crowd's deafening cheers, the five-strong band appeared knackered but elated.
They'd got the job done, and looked like they had a great time doing it.
Those planning to head along to their homecoming show in Dunedin on March 9 will not be disappointed.
