New Jersey Statutes Title 43. Pensions and Retirement and Unemployment Compensation 43 § 16A-3.4

a. Any member elected to public office may continue to be a member during the time he remains in such public office. The member's rate of contribution to the retirement system as applied to his salary as an elected official shall be the same rate, established pursuant to section 15 of P.L.1944, c. 255 (C. 43:16A-15), he paid prior to assuming elective office. The employer of the elected official shall make the employer's normal contribution and any accrued liability contribution to the retirement system on the basis of the member's salary as an elected official as provided in section 15 of P.L.1944, c. 255 (C. 43:16A-15) for so long as such member holds elective office and remains a member of the retirement system.

b. Any member of the retirement system who on the effective date of this amendatory act is an elected official and whose membership in the retirement system has been continued pursuant to the provisions of the act of which this act is amendatory shall have his rate of contribution thereto adjusted in accordance with the provisions of subsection a. of this section. The employer of the elected official shall make contributions to the retirement system on behalf of the member as provided in subsection a. of this section. No member who realizes a reduction in his rate of contribution as a result of subsection a. of this section shall be entitled to a refund of any contributions made to the retirement system prior to the effective date of this amendatory act which exceed the amount he would have contributed had his rate of contribution as an elected official enrolled in the retirement system been the same as provided by this amendatory act.
