Forest & Bird says efforts by farmers to protect our waterways aren't up to scratch.
The conservation group says our wetlands are still suffering under the strain of dairy.
A new three-year progress report reveals almost all dairy cattle are now fenced off from waterways, and 83 percent
farmers are getting information on nitrogen to help them farm more responsibly.
Forest & Bird advocacy manager Kevin Hackwell told Rachel Smalley some farmers still aren't pulling their weight.
"Yes, they've fenced an awful lot of the streams, but those are the biggest streams, what about the smaller ones where actually most of the pollution enters."
