"I use a semi-automatic in the high country because there's just so many pests there and they move so fast. Semi-automatics reload and allow further shots fast.
"My concern is that semi-automatics and military-style weapons will be lumped together as one in a possible law reform. Semi-automatics could be blanket banned which would hurt the farming community and those who have a legitimate purpose for having these guns," said the hunter who has an e-category endorsement.
That means he is licensed to own military-style weapons but he sees no legitimate reason why any New Zealander should own such weapons.
His comments come as Trade Me faces scrutiny for continuing to sell semi-automatic weapons on its site.
In response to criticism, Trade Me said it would "consider" making interim changes to the sale of hundreds of weapons on its site.
This also comes as retailer Gun City prepares to address the media in a press conference today.
Earlier, Gun City also came under fire over "poor taste" billboards spotted in Christchurch and Wellington. The store advertisement shows a man teaching two children how to aim at a target, with the quote "Get the family outside".
Guns are big business in New Zealand, with an estimated 1.2 million guns registered across the country.
