The Bay of Plenty Regional Council is nearing the end of a recruitment process to find a new chief executive.
Council chairman Doug Leeder said chief executive Mary-Anne Macleod's contract came up for renewal in March and she "elected not to express an interest in renewing it".
The council had since been working through a confidential recruitment process with a consultant.
Leeder said Macleod had been with the organisation for 11 years, the last seven as chief executive.
She had not been in the top job long when the Rena wrecked on Astrolabe Reef, a major issue she had to deal with.
