Contaminated Land


Contaminated land management within New Zealand requires the completion of specific assessment stages conforming to National Standards, namely for Assessing and Managing Contaminants in Soil to Protect Human Health. It is important that these standards are followed as local authorities within New Zealand are obliged to apply them when considering applications for land permits and consents. This may require the undertaking of a HAIL (Hazardous Activities and Industries List) investigation for the land before an application can be approved, to ensure there is no risk to human health or to plan mitigation if contamination is found to exist.

he Ministry for the Environment compiled the HAIL as a list of ‘activities and industries that are considered likely to cause land contamination resulting from hazardous substance use, storage or disposal. The HAIL is intended to identify most situations in New Zealand where hazardous substances could cause, and in many cases have caused, land contamination’. The full list can be found here.

Our Contaminated Land services include the reporting stages as directed by Ministry for the Environments’ Contaminated Land Guidelines, ensuring that councils and local authorities receive the information they need to address the relevant environmental issues for your site. These include:

  • Preliminary Site Investigations
  • Detailed Site Investigations

If contamination is shown to exist on site, we can conduct:

  • Site Remedial Action Plans

And if this remediation has taken place, we can certify remediation and provide ongoing observation through:

  • Site Validation Reports
  • Ongoing Monitoring and Management Plans

Haigh Workman will co-ordinate with relevant local authorities and the client to address and implement a site specific assessment to support the permit or consent, and to provide a cost-effective solution to assist your development.
