Former NSW Labor Party general secretary Jamie Clements has been charged by the New South Wales Electoral Commission for allegedly improperly accessing the electorate roll, the ABC's 7.30 program has revealed.

Political parties are given special access rights to voters' personal information on the electoral roll but are only allowed to use it for particular purposes.

The NSW Electoral Commission has alleged personal information was disclosed for a purpose not permitted under the Parliamentary Electorates and Elections Act.

Mr Clements has previously denied the allegations.

The NSW Electoral Commission has issued a short statement saying Mr Clements will appear in the Downing Centre Local Court on June 7.

"The NSW Electoral Commission has laid charges against a Central Coast man for disclosing protected information and, using enrolment information that had been provided by the commission for a purpose not permitted under the [Act]," the statement read.

Mr Clements is alleged to have disclosed the protected information in May 2015.

"Also, that in June 2015, the man used the information, that had been lawfully provided by the Electoral Commissioner to a registered party under the Act, for a purpose not permitted under the Act," the commission said.

Mr Clements is facing two charges under sections of the Act, the commission said.

The maximum penalty for each offence is $22,000.

A court appearance by a former senior Labor Party official is likely to be a damaging distraction in the last month of the election campaign.

Mr Clements declined to comment saying the matter was before the courts.
