New Jersey Statutes Title 11A. Civil Service 11A § 4-3

If it appears that an eligible list is not likely to provide full certification for existing or anticipated vacancies from among qualified residents of this State, or of political subdivisions where required by law, the commission may admit other qualified nonresident applicants. Where residency preference is provided pursuant to any other statute, the commission may limit applicants to such classes as are necessary to establish a sufficient pool of eligibles.
