Sh-Boom! Kiwi lads smash blind auditions on The Voice Australia with brilliant performance of classic

Meet the three Kiwi fellas joining a group of ex-pat New Zealanders looking to smash Australians at their own talent show, again.

The Koi Boys entertainment group, made up of Kiwi crooners Nuz Ngatai, Kevin Keepa and Danny Faifai, are the first ever trio to appear on The Voice Australia - and they nailed their blind audition.

Their audition was so bang-on, they managed to make all four judges - pop musicians Ronan Keating and Jessie J, Australian singer Delta Goodrem and American pop-rock brothers Joel and Benji Madden - turn their chairs.

The group has been singing together for almost 10 years, according to Channel Nine.

And it was their energetic and pitch-perfect performance of The Chords' 1954 doo-wop hit 'Sh-Boom' that had everyone buzzing.

Jessie J called it "the best vocal audition we've had tonight".

Judge Joel Madden even said the Kiwis were already contenders to win the show.

In the end, Jessie J's promise of being all about the harmonies was enough to secure The Koi Boys for her team.
