Button batteries

This product safety policy statement provides guidance for manufacturers and suppliers of button batteries to help reduce the risks associated with these items.

In 2023 the Ministry of Business, Innovation & Employment (MBIE) reviewed the policy statement and the Minister of Commerce and Consumer Affairs agreed to continue it. MBIE will review the statement again by 2 March 2028.
