Applying for a licence to transport or collect waste

The Council issues licences for companies collecting and transporting liquid waste.

To get a licence, you:

  • will be audited by the Council who will check that the waste you pick up is disposed of correctly
  • should comply with the WasteMINZ Liquid and Hazardous Wastes Code of Practice.

The Liquid and Hazardous Wastes Code of Practice was updated in 2012:
Liquid and Hazardous Wastes Code of Practice (2nd Edition) - WasteMINZ

To apply for a licence, call the Council and ask to speak to the Trade Waste Officer.

The Officer will arrange a time to check your control systems including waste types, mixing, volume and disposal to approved sites.
