About 150 people from across the country are expected to attend Saturday's event in the resort, including the mayor, or a council representative, from each region represented.
Southern regional finalists are: Luma Light Festival Charitable Trust (Queenstown Lakes), Salvation Army (Central Otago), Clutha District Settlement Support Inc (Clutha), South Invercargill Urban Rejuvenation Charitable Trust, South Alive (Invercargill City and Southland), Harbour Street Jazz Inc (Waitaki), Otago Special Olympics Powerlifting (Dunedin).
The awards recognise and reward the efforts of volunteers.
All finalists had been named the supreme winners at regional awards held across New Zealand last year.

Guest judges include Volunteering New Zealand chief executive Scott Miller, TVNZ Good Sorts creator and presenter Haydn Jones and former Supreme Winner Janice Lee, of Koha Kai.
The winner, runner-up and Whetu Mataiata award recipients will be announced at a formal event on Saturday night.
The winner will receive a custom-made trophy by Glenorchy artist Dan Kelly, $4000 prize money, a framed certificate and a $1000 consultancy voucher from Exult, a training provider for the community sector.
The runner-up will receive $2500 prize money, a $500 Exult voucher and a framed certificate, and the Whetu Mataiata Award winner will receive a framed certificate and a consultancy service package from Exult.
