"We have always emphasised the need for our funding dollar go as far as possible by having co-funding from funding recipients.
"After eight years it is pleasing to see the wider community match or better the authority's contribution to these important projects."
The authority has this year allocated up to $6m for clean-up projects.
Among the areas the authority has signalled it will be giving increased priority to this year include:
Restoration Strategy: Projects that have been identified as important in the Restoration Strategy will be given funding priority.
Partnerships: A greater level of support for applications that involve strong partnerships and that have the ability to deliver significant outcomes from larger projects.
Iwi Engagement: There will be an increased focus on bigger projects that incorporate iwi in the project delivery.
The projects seeking funding will now undergo a technical evaluation process from an advisory panel with the final funding decisions made by the authority and announced in November.
