Anti-gun lobbyists fear the new Government will erode firearms safeguards they gained after the Christchurch massacre.
ACT campaigned on dumping the firearms register and its MP Nicole McKee - the new Associate Minister of Firearms Reform - will launch a review next year and cut red tape from joining clubs and going to ranges.
It was less than a week after the March 15 massacre when the Labour-led Government announced a crackdown on guns, especially semi-automatics.
Nicole McKee led the charge against the legislation as the spokesperson for the Council of Licensed Firearms Owners.
Four years later, she's ACT's Cabinet minister in charge of firearms and is promising to rewrite the Arms Act.
"It's about making our communities safer and about having to have a regime where the firearms that are in circulation are in the hands of fit and proper law-abiding people," McKee said.
"We'll see what they propose but the indicators are they want to remove what is safe legislation," said Aliya Danzeisen, the national coordinator of the Islamic Women's Council.
McKee also wants an immediate repeal of tough restrictions on clubs and ranges, where they insist the focus is on teaching safety with guns.
"There were a lot of clubs that were in a lot of jeopardy, that the amount of compliance costs and paperwork that was going to be involved with being registered as a firearms club. There are some ranges that have closed or did not go through with the process because they just couldn't make it work," said Trevor Gratton, from the Hutt Valley Deerstalkers Association.
And while the Christchurch shooter was a member of a club in Dunedin, McKee said other club members put up red flags about him that weren't followed up.
McKee also wants to dump the firearms registry - a contentious move.
"Registering everything is not going to help keep New Zealand safe and actually ends up making criminals out of law-abiding people," McKee said.
But others say there's no room for error.
"We're edging on $2 billion just because of one shooter in Christchurch. $2b has cost this nation," Danzeisen said.
And for so many other reasons New Zealand can't afford another massacre.
