The Liquid and Hazardous Waste Code of Practice was originally published in 2003 and this document is its first revision.

The Code was developed to improve operating standards within the liquid and hazardous waste industry, enabling the establishment of the Liquid and Hazardous Waste Operators Certification Council who oversee a national audit and certification scheme. The aim of the Certification Council and the Code is to promote good practice across all levels of the industry.

The Code does not have its own statutory force. However, it is used by local authorities to support their trade waste bylaws and in the preparation of plans, policy statements and granting of resource consents under the Resource Management Act 1991.

The Certification Council can certify operators as ‘code compliant’. The Certification Council can also revoke this certification if a company fails to meet the requirements of the Code.

It is intended that the Code shall be revised and updated to reflect changes in regulations and improvements in operating practices.

The Code provides liquid and hazardous waste operators and the regulators and assessors of waste contracting services with practical advice on how to comply with legal requirements. These requirements include, but are not limited to, the RMA, the Land Transport Act 1998 (LTA), the Health and Safety in Employment Act 1992 (HSE Act), the Hazardous Substances and New Organisms Act 1996 (HSNO), and the New Zealand Waste Strategy 2010.
