Thames-Coromandel District Council's chief executive Rob Williams is leaving the council which has appointed Governance and Strategy group manager Rex Capil as interim CE.
Capil will take on the responsibilities effective immediately until a new, permanent chief executive has been appointed.
Williams has been in his position since 2016 after having been Taupo District Council's CEO for nine years.
The recruitment process to find a permanent replacement is under way and the council says it is expecting to fill the position by mid-year.
