A staffer for a senior NSW government minister was involved with a neo-Nazi infiltration of the state's National party, the opposition have alleged under parliamentary privilege.
The staffer also took paid leave to campaign for candidates with alt-right links in the US mid-term elections, Labor MP Walt Secord alleged in the NSW upper house on Thursday.
Mr Secord questioned what Roads Minister Melinda Pavey had done to remove the staffer from her office.
"What steps has Minister Pavey taken to remove this individual from her office and limit his influence on her portfolio responsibilities and decisions," Mr Secord asked in the Legislative Council's question time.
AAP understands the staffer took recreational leave to observe the US primaries last month and was not paid by the Republican candidate they spent time with.
Close to 20 NSW Nationals members resigned from the party in October amid an internal investigation into the alt-right infiltration of the party.
Screenshots of members arguing the merits of fascism, or making coded references to Hitler and skinheads on social media, have been seen by AAP.
NSW Nationals state director Ross Cadell defended the staffer and said he had been cleared by an internal investigation.
"We looked at dozens of people that had either a photo, a social network friend, or anything associated with this group and he came up clean in all respects," Mr Cadell told AAP.
A spokesman for Ms Pavey said no government staff, campaign staff, head office staff or members of the central council or executive were implicated in the internal investigation.
