Queenstown Lakes District Council chief executive Adam Feeley has called it quits.
A statement today from Mayor Vanessa van Uden said Mr Feeley would leave in late February.
He had told staff he was staying in the district and "looking forward to enjoying the outdoor lifestyle more while pursuing other opportunities''.
"We wish Adam well and thank him for what he has achieved in his three years with us.''
She would discuss the resignation with councillors at the earliest opportunity, and expected recruitment of a replacement to begin "swiftly''.
