N.J. Stat. Ann. § 54:50-30

2. All sales, transfers or assignments of indebtedness and liens represented by certificates of debt shall be to the highest bidder after public advertisement for bids therefor. Specifications and invitations for bids shall permit such full and free competition as is consistent with what will be most advantageous to the State based upon a present value analysis taking into account the likelihood of the State collecting the indebtedness within a reasonable time and other factors as the State Treasurer may determine. Notice for bids shall be in such manner selected by the State Treasurer as will best give notice thereof to bidders and shall be sufficiently in advance of the sales, transfers or assignment to promote competitive bidding. Any or all bids may be rejected if the State Treasurer determines that it is in the public interest to do so.
