A spokesperson said police had been made aware today of a "potential issue" by a member of the public.
"Immediately upon being made aware of the issue the platform was closed down and we are investigating the matter further," said the spokesperson.
"We have advised the office of the Privacy Commissioner of the potential issue.
"No further information is available at this time."
Deputy Commissioner Mike Clement will speak to media at 2pm about the issue.
The Council of Licenced Firearms Owners issued a statement on the matter.
"COLFO has learned within the past hour of a massive data breach on the police database for firearm hand-in and compensation," said spokeswoman Nicole McKee.
"Information on 70,000 firearm hand-in notifications, the firearms and owner bank account numbers, were accessible to web page users."
"COLFO has sent an urgent email to all members alerting them to the breach."
McKee said the organisation "demands that the web page and whole hand-in application programme is suspended immediately".
"The incident shows precisely why a police firearms register cannot be trusted."

Sums up the competency level of the Police and Government...If the data is misused, then class-action law suits for damages are likely to follow.
The whole law change fiasco was based on misinformation, lies and hysteria from the start. Honest, law abiding firearms owners have been scapegoated, short changed and targeted. Now they have had their personally information leaked, so now they and their families personal safety is at risk from criminal attack.
The people responsible need to be held to account, from the prime minister, the police hierarchy and police association rep', the police minister, down to our local MP's who have been arrogant and dismissive of law abiding firearms owners input and concerns.
People need to resign from the top down.
Good people are getting sick over this.
It needs to stop NOW.
