As a duo or in individual male and female sections, they have been prominent in the Kiwi Pro-Am Country Music for years and their dedication to traditional country music will be rewarded in LeMars, Iowa on August 26 (US time).

Hawkins said it was a huge honour for the duo to be inducted into the hall of fame.

Dennis Marsh, the Patumahoe-based builder turned singer, whose iwi affiliations include Ngapuhi and Ngati Hine and is now New Zealand's best selling country musician of all time, is a finalist in the Male Artists of the Year class at the national awards in Hamilton.
