N.J. Stat. § 31:1-1.1
Notwithstanding any provisions of R.S. 31:1-1 to the contrary, the commissioner may by regulation establish a rate of interest which may be charged by any person on loans made by them equal to the rate allowed by Federal law or regulation to be charged by national banking associations at any time when the rate so allowed by Federal law exceeds 8% per annum. Nothing herein shall authorize any person to make any loan which he is not authorized by law to make, nor shall anything in this act apply to loans secured by a first lien on real estate on which there is erected or to be erected a structure containing one, two, three, four, five or six dwelling units, a portion of which structure may also be used for nonresidential purposes.
Where in any other law a rate of interest applicable to loans regulated by this section is referred to as that established by R.S. 31:1-1, the rate applicable shall be as established herein.
