N.J. Stat. § 43:10-18.7
It is the intention of this act that the retirement system herein provided for shall on July first, one thousand nine hundred and forty-three, and thereafter, supersede and take the place of any county retirement system which shall be in operation in such county under and by virtue of the Revised Statutes, as follows:
County employees in counties of the first class (article one of chapter ten of Title 43, of the Revised Statutes);
County detectives in counties of the first, second, third and fifth classes (article two of chapter ten of Title 43, of the Revised Statutes);
Probation officers of counties of over eighty-three thousand inhabitants (article five of chapter ten of Title 43, of the Revised Statutes);
Sheriff's employees in counties of the first and second classes (article six of chapter ten of Title 43, of the Revised Statutes);
Sergeants-at-arms and court criers in counties of the first class (article seven of chapter ten of Title 43 of the Revised Statutes);
County superintendents of weights and measures and assistant superintendents of weights and measures ( "An act providing for the retirement of persons employed in the department of weights and measures of any county in this State, and providing a pension for such persons so retired," filed June twenty-first, one thousand nine hundred and thirty-eight) P.L. 1938, c. 397;
County park police in counties of more than two hundred thousand population (sections 40:37-157 to 40:37-174, inclusive, of the Revised Statutes);
and that such other county retirement systems shall be merged into and become part of the retirement system herein provided for and which shall be construed to be a continuation of such other county retirement systems; provided, however, that prior to such merger becoming effective, all such other county retirement systems shall be administered in accordance with the provisions of their respective statutes. If any of such other county retirement systems, created and maintained under and by virtue of said statutes, shall be in operation in any such county at the time of the adoption of this act, all moneys, appropriated and set aside by the board of chosen freeholders for pension purposes under such systems, securities and other assets of such other systems shall be transferred, on July first, one thousand nine hundred and forty-three, by the trustees of such systems, or the board of chosen freeholders, as the case may be, to the pension commission of the retirement system created by this act, which pension commission is hereby empowered to receive them, and the same shall become the property of and be placed in the retirement system herein provided for, and such other county retirement systems shall then cease to exist as separate retirement systems. If it shall not be possible or practicable for the trustees of any of such other county retirement systems to transfer all moneys, securities and other assets of such systems to the said pension commission on July first, one thousand nine hundred and forty-three, all such moneys, securities and other assets shall be transferred to said pension commission as soon as possible and practicable after such day, and any such transfer shall be made as of such day.
All pensions and other benefits allowed prior to July first, one thousand nine hundred and forty-three, under the statutes governing such other retirement systems shall thereafter be paid by the pension commission herein provided for from the retirement system herein provided for, according to the statute under which such pension or other benefits were allowed.
All claims for pensions or other benefits from such other county retirement systems which are pending or ungranted on July first, one thousand nine hundred and forty-three, shall be allowed or disallowed by the pension commission herein provided for according to the provisions of the statutes governing such other retirement systems, and those which shall be allowed shall be paid from the retirement system herein provided for.
