N.J. Stat. Ann. § 17:9A-8.12

12. All other powers, rights, and privileges not expressly provided for in this act shall be governed by the laws of this State relating to savings banks. If a capital stock savings bank engages in an activity pursuant to the authority of this act, or any other act, which is governed by a statute originally applicable to mutual savings banks, "manager" shall mean "director." In any case where any power of investment of a mutual savings bank is limited to a percentage of its capital deposits or surplus, any limitation upon a stock savings bank shall be expressed in terms of total capital funds, as defined by the commissioner by regulation.
