N.J. Stat. § 2C:27-9
A public servant commits a crime of the fourth degree if, while performing his official functions on behalf of a governmental entity, the public servant knowingly transacts any business with himself, a member of his immediate family, or a business organization in which the public servant or an immediate family member has an interest. For purposes of this section, an interest in a business organization shall not include aggregate familial ownership or control of one percent or less of an interest in the capital or equity of the business organization. A public servant shall not be guilty of an offense under this section if the public servant's performance of official functions would not affect the public servant, family member or business organization differently than such performance would affect the public generally, or would not affect the public servant, family member or business organization, as a member of a business, profession, occupation or group, differently than such performance would affect any other member of such business, profession, occupation or group.
