N.j. Ct. R. 6:4-5
All proceedings referred to in R. 6:4-3 and R. 6:4-4, including discovery in actions that are cognizable but not pending in the Small Claims Section, except for proceedings under R. 4:22 (request for admissions), shall be completed as to each defendant within 90 days of the date of service of that defendant's answer, unless on motion and notice, and for good cause shown, an order is entered before the expiration of said period enlarging the time for such proceedings to a date specified in the order. In actions transferred to the Special Civil Part pursuant to R. 4:3-4(c), however, the parties shall complete discovery within such time to which they would have been entitled under R. 4:24-1 had the action not been transferred.
