The National Party wants to keep dairy cattle away from all waterways and put $100 million towards retiring farmland next to sensitive waterways for use as environmental buffers.
Party leader John Key made the water quality announcement today at Waituna Lagoon in Southland, alongside environment spokeswoman Amy Adams and primary industries spokesman Nathan Guy.
The fund, over 10 years, would be used to buy and retire selected farmland next to important waterways to protect them from excessive dairying. The land could be used for environmental purposes, or community recreation.
National would also introduce a mandatory requirement to exclude dairy cattle from waterways by July 2017.
"New Zealand's water is among the very best in the world and we want to keep it that way. These are the next steps in our considered and sensible plan to continual improvements in freshwater quality," Ms Adams said.
