The Dunedin City Council has spent $36,000 sending chief executive Dr Sue Bidrose to leadership training courses at England's prestigious Oxford University.
Details of the four trips - which were supported by Mayor Dave Cull - were confirmed by Dr Bidrose last week, in response to Otago Daily Times questions.
Mayor Cull said it was important for the city, the council and its ratepayers that Dr Bidrose and other council staff were "as good as they can be".
Dr Bidrose, in an interview, said the trips came after she turned down a $15,000 annual pay rise late last year, and instead asked for the money to be put towards her own professional development.
The suggestion was approved by the council's seven-person chief executive performance review subcommittee, comprising Mr Cull, as chairman, and the heads of council committees.
