The NSW Director of Public Prosecutions would become the first state or territory prosecutor to have an arm dedicated to clamping down on public sector corruption under a set of new promises from the Coalition government.

The so-called Public Sector Prosecutions unit would focus on expediting complex criminal cases referred to the DPP from the Independent Commission Against Corruption, Premier Gladys Berejiklian will announce on Saturday, as well as producing confiscation orders designed to seize the assets of public officials who engage in misconduct.

"I have absolutely no tolerance for corruption," Ms Berejiklian said. "These tough new measures will help ensure that members of Parliament never forget that they have been elected by the community, and always remain accountable to the community."

It forms one of three pledges the Premier made to the electorate on Saturday ahead of the state's election in March. Another is set to extend the requirements for ministers to publish their diaries and overseas travel information to all members of Parliament.

The third will require lobbyists who are connected to foreign states or controlled entities to disclose these links on the public lobbyist register or face being blacklisted from meetings with government officials.
