"Once police are satisfied, the form will then be passed to the dealer by police following verification. This will negate any need for dealers to cross check details - though police will be continuing to audit dealers on a regular basis to make sure the system is working appropriately."
Gun City's millionaire owner David Tipple said he would go ahead with a private prosecution against du Plessis-Allan if a police investigation into the current affairs sting decided against prosecution.
"I'm ready for the battle. She's going down 100 per cent."
Law expert Professor Chris Gallavin, deputy pro vice chancellor at Massey University's College of Humanities and Social Sciences, said it was "likely" that du Plessis-Allan had committed an offence.
"But there is a broader public policy issue here, over whether we want good investigative journalism in New Zealand exposing things that under ordinary circumstances perhaps wouldn't have been brought to either the police or the public's attention. This is one of those cases where discretion should be exercised by police in not prosecuting."
TV3's Story broadcast about the gun purchase came after co-host du Plessis-Allan told Radio Live the .22 rifle had been bought for $300 using a fake name and fake gun licence.
"It wasn't difficult for me to do this. I didn't have to make fake IDs or anything."
MediaWorks journalist Duncan Garner, who interviewed du Plessis-Allen, said the rifle had been bought to test the law and there was a strong "public interest" defence.
A spokeswoman for MediaWorks said: "We believe it is in the public interest that this serious loophole in the gun laws is closed. We support this story and the Story journalists completely."
