Firearm owners say a "prohibited persons register" should be created to stop "unfit" people from getting firearm's licences.
The call from the Council of Licenced Firearms Owners (COLFO) comes after a coroner's inquest into the deaths of Constable Len Snee and gunman Jan Molenaar during a Napier siege last year.
Molenaar, 51, shot and killed Mr Snee and wounded senior constables Grant Diver and Bruce Miller, after the officers tried to carry out a cannabis search warrant on May 7. Molenaar eventually turned his gun on himself, ending the three-day siege.
Molenaar had shown he was not a "fit and proper" person to hold a firearms licence before the siege and should not have been allowed to hold one, COLFO chairman, Michael Dowling said.
While New Zealand had some of the best gun laws in the world, the Napier siege showed there needed to be better mechanisms to identify whether people were fit enough to hold a licence, Mr Dowling said.
"We need to empower professionals, friends and family to raise red flags around individuals who should not have or no longer have access to firearms," he said.
Responding to the coroner's call for the Government to review the Arms Act, Mr Dowling said it was important that any review be balanced and not "hijacked by emotion".
"While it is understandable for people to look to others or inanimate objects to blame in cases like this, we believe the answer lies not in more firearms laws for those who adhere to them but in ensuring clear guidelines for legitimate users," he said.
