The NSW corruption watchdog is due to submit its report next week from an inquiry that ended former Wagga MP Daryl Maguire's career in 2018.
A statement from the Independent Commission Against Corruption (ICAC) said it would "furnish its Operation Dasha investigation report, concerning the former Canterbury City Council, to the President of the Legislative Council on March 22 at 2:45pm".
The upper house president will decide if the report is made public.
Mr Maguire resigned from Parliament in August 2018, more than three weeks after he first appeared at an ICAC hearing in Sydney.
Operation Dasha was not set up to investigate Mr Maguire directly, but he was caught on intercepted phone calls speaking with Canterbury councillors who had been targeted by ICAC.
ICAC questioned Mr Maguire over him telling a councillor that his "mega big" client with "mega money" would buy projects with planning approval and he wanted a 3 per cent dividend.
Mr Maguire quit the Liberal Party and his parliamentary secretary positions soon after his ICAC appearance.
ICAC then launched Operation Keppel to investigate Mr Maguire and held public hearings late last year.
