Contaminated Sites Knowledge Hub
Contaminated sites are a legacy of our past land use and activities. Land contamination has the potential to have adverse effects on people, property and the environment both within source sites and beyond their boundaries as a result of contaminant migration. Our Land 2018 Report confirmed that the overall extent of land contamination in New Zealand is unknown. It has been reported that nearly 20,000 sites nationwide have been identified as HAIL land. However regional councils have estimated that up to three times as many HAIL sites could be identified.
While the government’s current environmental priorities have moved away from a focus on regulatory amendments to the contaminated soils assessment and management regime, issues relating to contaminated sites and their investigation, management and remediation remain highly important given their potential impact and widespread relevance throughout the country.
