Invercargill Mayor Nobby Clark is scheduled to undergo heart surgery next week, after suffering a minor heart attack on Wednesday.
Clark was taken to Southland Hospital and stayed overnight as a precaution after the incident on December 27, the council said.
He was then transferred to Dunedin Hospital for more tests yesterday.
