N.J. Stat. § 43:7-15: Suspension or discharge

If any such prison officer shall be suspended, resigned, dropped or discharged from his employment after having paid the aforesaid assessments for a period over one year, and whose suspension or discharge shall continue for a period longer than two years, he shall be entitled to the return of such moneys as he shall have paid into such pension fund by reason of the assessments aforesaid, but such person shall not thereafter be eligible for a pension under this act unless upon a re-employment by the State he shall repay to such fund the amount of any rebate made to him. The obligation to refund payments made to the pension association shall not apply to any pension officer suspended or discharged for causes which bar him from eligibility to reappointment under the civil service rules. No other refund of assessments collected from the salaries of such pension officers shall be made.
