The seat on Whangārei District Council vacated by former councillor Stu Bell will remain empty until the local body elections later this year.
Bell resigned as a councillor at the beginning of this month.
At the time he said: "Local government should in my opinion operate with the legislative framework it is bound by and be open, transparent and respectful to view of the communities it serves."
Bell said "too many things" had happened recently, mostly under the cover of confidentiality, that he believed indicated the council had forgotten that.
He said he had for the most part enjoyed the debates with other councillors when making decisions and working with council staff to deliver positive outcomes.
