N.J. Stat. § 30:4-84.3
The transfers as heretofore provided may be temporary or indefinite; if temporary, the status of the individual shall be governed by the statutory provisions covering admission and discharge under which he was receiving care or treatment in the sending institution or service; if indefinite, the status of the individual shall be governed by the statutory provisions applicable to the receiving institution, to which he shall be considered to have been admitted in the same or most comparable class as that under which he was receiving care or treatment in the sending institution or service, unless a new court order shall supervene. Admission to any institution or service on indefinite transfer shall constitute discharge from the sending institution or service.
