N.J. Stat. § 17B:34-5
Whenever any matter is required to be submitted, filed or otherwise presented so that it may be brought to the attention of the commissioner, then, unless a different time is specified in the applicable provision, the same shall be taken to have been approved upon the expiration of 30 days after the filing thereof if no notice of disapproval, or of suspension and inquiry, shall be issued and if the matter is not withdrawn, within such time. The commissioner may extend the 30 day period referred to in the preceding sentence for not more than 30 additional days by giving written notice of such extension before the expiration of the initial 30 day period. In the event of such extension, the provisions of this section, except the provision for extension, relating to the initial 30 day period, shall apply to the extended period instead of such initial 30 day period. Approvals taking effect pursuant to this section may be relied upon by all persons with like effect as though there had been an affirmative written approval, during such a period as may ensue thereafter prior to the making of a subsequent order of disapproval on notice and hearing.
