Campbell Landrebe (12) sang at the Southern Alps Country Music Awards in Timaru for the first time at Easter and took home seven trophies.
He and his sister, Alyssa (9), also won the junior duo category for their performance of Make The World Go Away, by Alison Krauss and Jamey Johnson.
The Landrebes also won the junior runner-up prize.
Campbell, a year 8 Balmacewen Intermediate pupil won prizes in gospel, country rock, solo and the overall junior prize.
''I jumped up and went 'Yes','' Campbell said, recreating a celebratory punch of the air he made at the awards ceremony.
The songs he performed to win included God Bless Texas, by Little Texas, Oklahoma, by Billy Gilman, and Last Train Running, by Whiskey Falls.
His prize haul included a new guitar and $540 prize money.
Alyssa, a year 5 Wakari School pupil, said the two siblings performed to a crowd of about 250 people on the final night.
''It was really cool,'' she said.
Campbell gave $160 of the prize money to his sister, more than the amount she won, because he had enough to buy a pickup for his guitar and to get their names engraved on the trophies.
The sibling's sights were now set on their first performances at the New Zealand Gold Guitar Awards in Gore next month.
