Bay of Plenty Regional Council has spent $1.67 million supporting 259 landowners to put Riparian Management Plans (RMP) in place.
Tauranga catchments manager Sarah Omundsen said money was spent during the 2012/13 and 2013/14 financial years with subsidies still available.
That expenditure meant 356km of river and stream margins were protected and 180ha of erosion-prone land converted to more sustainable use, she said.
The programmes were important to stop erosion and promote healthy waterways.
"Valuable, productive soil generates the best benefits for landowners if it can be retained on the property. Fencing and planting of waterways and steep land traps soil and reduces stream bank erosion so that less sediment and fewer nutrients are washed off the land into local waterways.
