Mr Heckler said Otago Fish and Game used to co-ordinate, organise and contribute to the culls, but then "walked away, and left landowners [and] dam operators with the problem they had arguably created".
The geese were now culled "from time to time" because there were so many of them, Mr Heckler said.
"They badly foul the water, pasture and crops, not only in the area adjacent to the water body."
All the shot birds were collected and buried, he said.
Otago Fish and Game chief executive Ian Hadland confirmed Fish and Game no longer managed Canada geese as a gamebird.
"The Minister of Conservation changed their legal status under the Wildlife Act from a 'gamebird' to 'not protected' in 2011 after significant lobbying by Federated Farmers to have their protective status removed.
"This ended decades of hunter- funded management of the species through a South Island Management plan which had set limits on numbers.
"Since 2011 there has been an expansion of the range of [the] Canada Goose and in some places, increases in numbers. Nuisance populations of geese are now being culled by landowners, often by helicopter, at their own expense."
