Australian folk singer Fanny Lumsden and Invercargill singer Suzanne Prentice are headlining the week-long festival.
Southland-based acts Ron and Jenny Mitchell, Kayla Mahon, the Mitchell Twins, Jeff Rea and others will be joining the action, too.
Festival organisers have partnered with Allied Press to host the ODT Tussock Stage, which will feature songwriters Mel Parsons, Sam Bartells, Katie Thompson, the Mitchell Twins, Kayla Mahon, the Dollys and Maia Pereiha-Fletcher across four shows.
The stage will provide a platform for New Zealand musicians to present their original music.
The MLT NZ Gold Guitar Awards, Tussock Country Ute Muster and Freeze Ya Bits Off Busking will all return.
However, there will be an event exclusive to this year’s festival.
The world premiere of Capital of Country Music, a documentary chronicling the 50-year history of the Gore Country Music Club, will be shown.
More than 60 events will take place at the festival, which runs from May 24 to June 2.
