N.J. Stat. § 40:41A-30
The grant of powers under this act is intended to be as broad as is consistent with the Constitution of New Jersey and with general law relating to local government. The grant of powers shall be construed as liberally as possible in regard to the county's right to reorganize its own form of government, to reorganize its structure and to alter or abolish its agencies, subject to the general mandate of performing services, whether they be performed by the agency previously established or by a new agency or another department of county government. All county offices, boards, commissions and authorities authorized or established by statute, other than an authority organized under the "municipal and county utilities authorities law," P.L. 1957, c.183 (C.40:14B-1 et seq.), those boards and offices which are subject to the provisions of subsection b. of section 125 of P.L. 1972, c.154 (C.40:41A-125), and other than educational institutions authorized or established pursuant to Title 18A of the New Jersey Statutes, shall be considered to be county agencies for the purposes of this section.
Based on the need to develop effective services to meet problems which cross municipal boundaries and which cannot be met effectively on an individual basis by the municipalities or the State, this act shall be construed as intending to give the county power to establish innovative programs and to perform such regional services as any municipality or the State may determine, in its own best interest, to have the county perform on a contractual basis.
