Six million dollars is available for people who want to help clean up the Waikato River.
The Waikato River Authority, a co-governance body of the Crown and local iwi, is responsible for administering a clean-up fund of $210 million over 30 years.
Applications for the first round of funding began at the start of October and close on December 16.
The authority says there has been a high interest so far and meetings have been arranged with groups that have ideas for the clean-up.
Authority co-chairmen Tukoroirangi Morgan and John Luxton said they were keen to receive even more applications and wanted to work with those submitting them as closely as possible.
