N.J. Stat. § 40:11A-7
An authority shall have right to acquire by the exercise of the power of eminent domain any real property which it may deem necessary for its purposes under this chapter after the adoption by it of a resolution declaring that the acquisition of the real property described therein is necessary for such purposes unless in the resolution or ordinance creating the authority it is provided that no real property shall be acquired in said manner without the consent of the governing body, in which case said power shall not be exercised without said consent. Property already devoted to a public use may be acquired in like manner provided that no real property belonging to a public body or any corporation itself possessing the power of eminent domain may be acquired without its consent.
