Clean-waterways advocate Millan Ruka says there is "too much hui but little doey" when it come to keeping farm stock out of waterways.
In response to concerns about faecal contamination in the popular swimming hole at Whangarei Falls, Mr Ruka, from Environment River Patrol Aotearoa, said effluent from cows fouling Waitaua Stream would take less than two hours to flow downstream to the Falls.
Mr Ruka said he recently notified Northland Regional Council (NRC) and supplied photos of cows grazing the banks and getting into Waitaua Stream 2.5km up from the Falls, where a permanent Whangarei District Council health warning about faecal contamination is posted. Despite the health warning, the spot remains a popular swimming area.
Mr Ruka's February report to the NRC included notification of a sheep carcass upstream from the Falls which was removed some days later. He said he had made three reports regarding contamination by dairy cows and cattle at the same site since November 2013.
"But I do see some activity with a trough and pond going in. Maybe a fence will come later," he said.
