Mayor Mufi Hannemann today named Kirk Caldwell his new managing director, the city's highest appointed post.

Caldwell is an attorney and former state legislator.

Hannemann praised Caldwell for his work on the recent Rail Transit campaign and said he looked forward to working with a man of his experience.

Caldwell said he was "honored" to be given this opportunity. He said infrastructure will be among his priorities as managing director.

Caldwell replaces Wayne Hashiro, who resigned earlier this month and has since accepted a position with the Board of Water Supply.

Caldwell begins his duties immediately. City spokesman Bill Brennan said Caldwell will serve as acting managing director pending City Council confirmation.
