N.J. Stat. § 54:1-33

The commissioner shall annually, after receiving from the county boards of taxation the abstracts of ratables as last certified by such boards, inquire into and determine the general ratio or percentage of full value at which the real property within each county is assessed and listed for taxation, and shall prepare a state equalization table of county ratables, showing the assessed valuation of real and personal property in each county, the ratio or percentage, if any, by which the assessed valuation of real property of each county should be increased or decreased to correspond to true value, and the true valuation of real property as determined by him. A copy of the table shall be mailed to the county board of taxation and director of the board of freeholders of each county, and to the state comptroller, and posted at the state house, at least ten days before the hearing provided for in section 54:1-34 of this title.
