Government restrictions on where helicopters can fly make it difficult for hunters to find other places to hunt tahr, according to Tahr Foundation chairman Snow Hewetson.
In a statement yesterday, New Zealand Conservation Authority chairman Edward Ellison supported the Department of Conservation's plan to eradicate tahr from the Aoraki/Mt Cook and Westland Tai Poutini National Parks.
Ellison also said the two parks made up "roughly 20 per cent" of the tahr feral range.
"So there is significant alternate opportunity for tahr hunting in New Zealand to continue on public conservation land."
Hewetson described that suggestion as "a bit disingenuous".
