Environmental pollution

Updated 30 March 2020 3:22pm

During the COVID-19 Lockdown we have changed our response to pollution incidents, in line with government guidelines, to reduce the likelihood of spreading the virus and of our staff becoming infected.

We still have a 24/7 environmental hotline 0800 496 734 which you can report any incidents to. Our officers are triaging all incidents which come in. We will only physically respond to the most significant incidents where there are immediate and serious adverse environmental effects (in particular if there is risk to human health).

All other incidents will be responded to in other ways. If you leave your name and number when contacting us we will get back to you as soon as practical.

See below for a list of the types of environmental incidents which fall within Greater Wellington Regional Council remit:

  • Water pollution (discharges to streams, rivers, lakes, aquifers and the coastal marine area)
  • Land pollution (dumping and spillage of materials that contaminate land)
  • Air pollution (dust, smells/odours, smoke from outdoor fires where hazardous materials (including plastic, treated timber and metal) are being burnt)
  • Taking water (groundwater, surface water and draining wetlands)
  • River works (channel/river mouth cutting, vegetation removal, diversions, excavations, gravel extractions, deposition and disturbance)
  • Earthworks (large scale vegetation clearance, earth moving, tracking, cut and fill etc)
  • Buildings and structures in rivers/stream and the coastal marine area (construction, demolition, maintenance etc)
  • Noise originating from the coastal marine area (from boats and ships etc)
  • Animals in rivers, streams and the coastal marine area (discharges, disturbance, carcasses etc)
  • Hazardous substances (discharges into water or land)


Under the Resource Management Act 1991 (the Act), Greater Wellington Regional Council has a regulatory responsibility to monitor, gather information, and keep records. More...
