N.J. Stat. § 40A:4-20
In addition to temporary appropriations necessary for the period prior to the adoption of the budget and regular appropriations, the governing body may, by resolution adopted by a 2/3 vote of the full membership thereof, make emergency temporary appropriations for any purposes for which appropriations may lawfully be made for the period between the beginning of the current fiscal year and the date of the adoption of the budget for said year. The amount of such emergency temporary appropriations shall be included under the correct headings in the budget as adopted. If they are adopted after the introduction and approval of the budget and were not included in the budget as approved, they shall be included by amendment in the budget as adopted, except that no public advertisement or public hearings shall be required as to their adoption as amendments.
A copy of each resolution making such emergency temporary appropriations shall be filed forthwith with the director.
