Appearing briefly in Newcastle Local Court on Thursday afternoon via audiovisual link from the Metropolitan Remand and Reception Centre, Bjorn Johnson pleaded guilty to one count of resisting arrest.
Legal Aid defence lawyer Matthew Kilkeary told the court separate charges involving the painting of a swastika in a public place had yet to be resolved.
Mr Kilkeary said police had provided him with some photographs from the brief of evidence but not everything had been handed over by investigators.
Magistrate Caleb Franklin agreed to adjourn the case to March 13.
At a previous court appearance in January, Johnson, 47, of Wadalba on the Central Coast, indicated he planned to plead not guilty to charges of knowingly displaying in public a Nazi symbol without excuse and marking a premises without excuse.
Johnson, who had been on parole for assault at the time, faces a maximum penalty of 12 months' jail and $11,000 fine if convicted.
Police claimed Johnson painted the Nazi symbol on the side wall of a chemist's shop in the Newcastle suburb of Hamilton some time after 7.30am on January 12.
Johnson was arrested nearby a few hours later. He spent four nights in custody refusing to talk to anyone after his arrest.
He was granted bail in January with strict conditions, including reporting daily to Wyong police and not entering Hamilton. But the magistrate ordered Johnson, who lived on his own, not to be released until he could provide a character witness to confirm they knew him and could vouch for him as a responsible person who would comply with his bail.
He remains in custody.
