The South Australian government had denied using state websites to collect and track data for the Liberal Party.
Recent media reports suggested people accessing government websites were being redirected through a data harvesting platform called NationBuilder.
But Premier Steven Marshall said on Tuesday there had never been any retention of information.
"No data is being collected or retained when clicking on the links referred to in media reports," Mr Marshall said in a statement.
"As Nationbuilder has confirmed this morning, 'this URL is not redirecting any users to NationBuilder's platform - it is a reference link generated by Mimecast, a website analytics provider and no data is being collected or retained when users click on these links'."
Mr Marshall said it was likely that when parts of media releases were copied and pasted into SA government websites, the original links were still being detected by Mimecast.
The premier said to ensure there was no confusion amongst journalists or members of the public, the government would now use a different system for distributing media releases.
But the Labor opposition called for an independent inquiry into the issue.
Government accountability spokesman Tom Koutsantonis said South Australians turned to government websites for trusted information and had every right to ask what was happening to their personal data.
