High entry numbers had caused a few "minor" logistical problems, but earlier-than-usual, 8am starts for auditions in many classes had kept things running on time, he said.
Quantity had been matched by quality throughout.
"What's remarkable is how the overall calibre of entrants just keeps improving year on year. I think audiences were particularly impressed with Saturday's junior and intermediate finalists, which is great news for the future of New Zealand country."
A panel of nine judges also had their work cut out to pick senior winners at the Gore Town & Country Club Stadium last night, Geary said.
Competitors had every incentive to pull out all the stops, as 2017 Gold Guitar winner Jenny Mitchell emerged a victorious Tui winner at this year's Gore-hosted New Zealand Country Music Awards on Thursday.
"We've watched Jenny come through from the juniors at 5 or 6, to her success at the highest level this week. She's a great ambassador for country music in New Zealand. We're very proud of her."
Gold Guitars intermediate overall winner was Ocean Waitokia (16), of Ashburton; junior overall winner was Caleb Croy (12), of Mosgiel.
