Christchurch City Council has dropped an investigation into allegations of misconduct by a former councillor.
Deon Swiggs was investigated after five youths complained of inappropriate messages and being made to feel uncomfortable - with two found worthy of further investigation.
But chief executive Dawn Baxendale has confirmed in a letter to Swiggs' lawyer that no further investigation will proceed.
In the letter, she said now Swiggs is no longer a councillor, there is no meaningful provision in the Code of Conduct for the Council to take action against him.
Earlier this week, a formal complaint was filed over mayor Lianne Dalziel's handling of the situation - having told complainants in June the process to resolve such complaints was "extremely poor".
