A statement from Mr Findlay on Friday said he regretted his actions and agreed they were wrong.
He also resigned as a board member of Q-topia, a social support group for gay, lesbian, bisexual, transgender and intersex youth aged 14-25 in Canterbury.
The group accepted the resignation.
"We understand that at no time did any interaction progress beyond the online environment,'' Q-topia said in a statement.
"As a board, we have every confidence that Paul's time on the Q-topia board was undertaken with the utmost integrity, and that he maintained the highest standards that are expected of all board members while undertaking Q-topia duties.
"We respect Paul's decision to remove himself from the board, and believe that this decision has been undertaken to ensure that the Q-topia standards are not affected in any way.''
