Changes to the Truth will be rolled out over several months and will include the development of a news website to support the paper, Slater said.
He said the paper would focus on uncovering political dishonesty and scandal.
"We're going to keep the buggers honest. There's no better disinfectant than sunlight."
The first issue of Truth to be edited by Mr Slater is due to come out on November 8. He said he would continue blogging at Whale Oil.
Mr Slater had an extra-marital affair outed in a court judgment issued in June.
He has previously been convicted in the High Court of breaching name suppression orders on criminals.
