New Jersey Statutes Title 19. Elections 19 § 32-34

The superintendent, his chief deputy or assistants, shall have the power, when in his or their judgment it is deemed necessary at any election, upon the completion of the counting and canvassing of the ballots by any district board, to enter any place containing ballot boxes for the purpose of taking possession and sealing any ballot box or boxes with a seal to be adopted by the superintendent. When any ballot box shall be so sealed it may be removed to a vault or other place of security by the superintendent, his chief deputy or assistants, but shall not be opened and the seal thereof destroyed or affected without an order first had and obtained from a judge of the Superior Court assigned to the county. Taping or any other mechanical device may be used to make such sealing secure.
