• Introduced new sections 6B and 6C of the Arms Act. New sections detailed new conditions for dealers manufacturing and what happens if conditions are breached.
• Amended section 12 of the Arms Act. This replaced the dealer book recording requirements for dealers, enabling dealers to record their transactions electronically and to replace their hard copy books with electronic versions. 
• Section 109 of the Arms Act introduced. This section detailed technical and language amendments to the Arms Regulations, which included changes to reflect the new five year licence period for first time applicants and revoked regulations 7(9) and (10) of the Arms Regulations.
