"It’s a visual feast and I’m thrilled with the number of entries," show co-ordinator Stuart Brown said.
Canadian judge Anne Kenney said the variety of dahlias on show was "amazing and it’s great to see New Zealand [bred] ones".
In the end, Waikouaiti couple Donna and Wayne Burgess took out the Champion of Champions accolade for their large semi-cactus variety "Light Accord". They also won numerous other awards, including best vase for a beautifully matched trio of miniature ball "Amy Cave".
"We’re ecstatic. It’s a great result for us and the Dunedin Dahlia Circle, achieving this on our own ground."
