Country Rock Festival patron Dennis Marsh was surprised during a show in Paihia with a platinum album award for his 2011 CD, Maori Songbook.
Marsh's performance was interrupted by festival organiser Shirley May, of Pakaraka, who sprang the surprise on behalf of Rajon Records.
The Patumahoe-based builder turned singer, whose iwi affiliations include Ngapuhi and Ngati Hine, is now New Zealand's best selling country musician of all time.
His Maori Songbook CD hit number one in the national charts last year and outsold 2011 releases by international stars Lady Gaga, Katy Perry and Adele in New Zealand.
Mrs May said other highlights of the May 10-12 festival included "voice in a million" Eddie Low of Christchurch and New Zealand's best female country artist of 2010 and 2011, Tami Neilson. Australia's Royden Donohue and Aaron Jury of Kaitangata had also "gone down amazingly well".
