Federated Farmers has called for Rotorua's regional authorities to come up with practical solutions to help farmers improve water quality in local lakes rather than imposing strict regulations.
Sewage and nutrient leaching from farms have damaged water quality, and resulted in toxic algal booms in the region's lakes.
The Government has committed $72 million towards cleaning up the four worst-polluted lakes. Measures will also be needed to improve Lakes Rotorua, Rotoiti, Rotoehu and Okareka.
Federated Farmers spokesperson Lachlan McKenzie says farmers enjoy using the lakes for recreational purposes, and are committed to improving water quality.
But Mr McKenzie says some real solutions need to be found before any regulation is rushed through.
