This section provides links to the New Zealand Waste List (L-Code). The L-Code was adapted from international lists and has been modified to reflect typical waste streams in New Zealand. The L-Code provides guidance on identifying wastes in a consistent manner and serves as the basis for record-keeping systems, particularly for hazardous wastes.
The specific waste streams for the industry you are seeking are listed below. Note that each waste is assigned a unique 6-digit code (L-Code). Wastes marked with an asterisk (*) after their L-Code should be treated as hazardous.
