N.J. Stat. § 17:9A-23.52
Whenever the officers of a bank are of the opinion that an emergency exists which affects one or more or all the bank's offices, they shall have authority to close one or more or all such offices even though the commissioner has not issued and does not issue a proclamation of emergency, and they may, but need not, provide that the business normally transacted at a closed office will be transacted at another office designated by the bank until further notice. The office or offices so closed shall remain closed until the commissioner proclaims that the emergency has ended, or until such earlier time as the officers of the bank determine that one or more offices, theretofore closed because of the emergency, should reopen, or, if the commissioner has issued no proclamation of emergency, until the officers of the bank determine that such office or offices should reopen. The discretion of the officers in acting pursuant to this section, when exercised in good faith, shall not be questioned in any court or place.
