Hartcher tendered his resignation on Wednesday following the issue of a search warrant against him by the ICAC.
“I am confident I will be cleared of any wrong doing,” he said.
“This is the first contact I have had with the ICAC and given that their investigations have thus far had an unknown timeframe, it is appropriate that I resign.
“I will continue to serve as Member for Terrigal while I await the outcome.”
