Any member who, having elected to receive a deferred retirement allowance, again becomes an employee covered by the retirement system while under the age of 60 or, if that person became a member of the retirement system on or after the effective date of P.L. 2008, c. 89, while under the age of 62, shall thereupon be reenrolled. If he had discontinued his service for more than two consecutive years, subsequent contributions shall be at a rate applicable to the age resulting from the subtraction of his years of creditable service at the time of his last discontinuance of contributing membership from his age at the time of his return to service. He shall be credited with all service as a member standing to his credit at the time of his election to receive a deferred retirement allowance.
