"However, several hundred dairy and beef cattle are unfenced to the waterways of the Hatea Catchment and there is a Code Red issued at the Whangarei Falls where all these streams feed to."
Mr Ruka said many dairy farmers now fenced off waterways because Fonterra would not collect suppliers' milk if they contravened a clean-water accord, but no accord applied to drystock.
He described the NRC's new 10-year policy review of the Regional Water and Soil Plan as "a nonsense" that had been hijacked by commercial interests.
"The NRC showed their existing policy on cattle on unfenced waterways and it was less than half a page. I pointed out that Whangarei District Council had 22 pages on by-laws for parking your car in this city and yet you can park 400 head of cattle on a riverbank and it's all okay."
Mr Ruka said he will continue to campaign for "quality over quantity" regarding water use, to have drystock included in stock-exclusion fencing rules, and for a tougher stance on non-compliant effluent ponds.
"Where is the independent balance to keep this all in check? We have all sorts of agencies for noise control, dog rangers, parking wardens, etc, but no independent waterway patrols for the combined $23 billion dairy and beef industry," he said.
"Instead, we spend hundreds of millions of dollars monitoring how bad it's getting. Everyone wants to study it, there's a lot of hui but little doey."
