N.C. Gen. Stat. § 65-54.1
Records, papers, and other documents containing information collected or compiled by the Commission, its members, or employees as a result of a complaint, investigation, inquiry, or interview in connection with an application for license, or in connection with a license holder's professional ethics and conduct, shall not be considered public records within the meaning of Chapter 132 of the General Statutes. Any notice or statement of charges against a license holder or applicant, or any notice to a license holder or applicant of a hearing to be held by the Commission, is a public record even though it may contain information collected and compiled as a result of a complaint, investigation, inquiry, or interview conducted by the Commission. If any record, paper, or other document containing information collected and compiled by the Commission is admitted into evidence in a hearing held by the Commission, it shall then be a public record within the meaning of Chapter 132 of the General Statutes.
