The situation is clouded by the fact Mr Simpson's executive assistant Ford Watson helped mayoral candidate Warwick Syers with advice on some of his election statements. Mr Syers said Mr Watson had provided "wordsmithing" in his own time and had permission to do so from Mr Simpson.
After meeting for more than an hour Mr Halse said a committee of three councillors, including himself, but excluding any of the four councillors running for mayor - Mr Syers, Shelley Deeming, Greg Martin and Crichton Christie - had been appointed as a review committee to look into the employment matters raised and report to the full council.
Mr Halse said a suitably qualified independent person with a background in employment law would chair the committee, which would start work once that person was appointed. That could be as early as today and would be given urgency with a result "hopefully" released before the October 12 election.
The CEO was responsible for all council employment matters and as such it was inappropriate for individual councillors and the council as a whole to comment on them.
The review committee would look into the circumstances of Mrs Walters' sacking and Mr Watson's work for Mr Syers.
In June the council set election protocols for its employees saying they should remain politically neutral in their dealings with elected members and the public during the campaign.
