To help improve catchment areas, $12 million has been set aside, with the first share of funding earmarked for cleaning up the Kaipara Harbour in Northland.
Prime Minister Jacinda Ardern said estuaries like Kaipara are clogged with sediment and mangroves. Kaipara is the country's largest estuary.
Actions in the area would include riparian planting and wetland preservation and development; fencing streams to prevent livestock trampling at waterway margins; and using the best science to locate sediment hotspots and measure sediment flows.
"The direction of travel is clear: we need to reduce the pollution - nitrogen, sediment, E coli and other contaminants - from flowing through our cities and farms and into our waterways," Ms Ardern said.
Ms Ardern praised farmers working to improve water quality.
She said the owners, who had fenced streams and wetlands, are showing the sort of leadership needed to clean up the rivers that flow into the Kaipara harbour.
It was very clear at the time of the election that everyone wants to be able to swim in their local river without getting sick, she said.
The first tranche of the funding will go to the Kaipara Harbour Management Group - which includes farmers, councils, hapū and schools.
However Ms Ardern was not able to say at this stage how much that would be.

Environment Minister David Parker said the government was working with the Kaipara community to help understand what can make the biggest difference, before deciding what action to take - such as where to build and restore wetlands, or where more hillside planting is required to stabilise steep land.
"Volunteers, iwi, local government, farmers and school students are all working together to improve the quality of the water flowing into the Kaipara harbour," Mr Parker said.
"Those lessons from 'exemplar' catchments like Kaipara will be passed on to others."
Mr Parker said the work is much needed.
"I think it's fair to say some of our estuaries are in a crisis. They've suffered the consequences of some very intensive farm practices following forests being cleared a long, long time ago and then in recent decades more intensive forms of farming have increased the loads of sediment and nutrients that are clogging them up."
Mr Parker said more catchments would be identified in coming months.

This year's budget included $229m to help improve land use and waterways.
The Labour-led government had promised to stop the degradation of waterways, reverse the damage and make measurable improvements within five years.
