Contaminated land management guidelines
The Ministry for the Environment has developed a series of contaminated land management guidelines so contaminated land is assessed and managed consistently throughout the country. The guidelines, developed in partnership with regional councils and unitary authorities, are listed below.
- Contaminated Land Management Guidelines No. 1 – Reporting on Contaminated Sites in New Zealand (Revised 2011) details the type and amount of information required in a contaminated site report.
- Contaminated Land Management Guidelines No. 2 – Hierarchy and Application in New Zealand of Environmental Guideline Values (Revised 2011) ensures the consistent selection and application of environmental guideline values.
- Contaminated Land Management Guidelines No. 3 – Risk Screening System describes the Risk Screening System which provides a nationally consistent way to rank sites that are, or are suspected of being, contaminated. The purpose of ranking a site is usually so it may be prioritised for further investigation.
- Contaminated Land Management Guidelines No. 4 – Classification and Information Management Protocols suggests a nationally consistent way to classify, manage and release contaminated site information held on council registers or databases.
