Federated Farmers is seeking a ''targeted catchment approach'' to addressing water quality, where sustainable economic growth could be achieved alongside environmental goals.
The rural lobby organisation has launched its manifesto before this year's election, challenging political parties to take a sensible, practical and affordable approach to tackling issues of high importance to its members.
It supported a framework for catchment partnerships that co-ordinated community, council and scientific efforts.
''This could involve a range of taxpayer and region-wide rates-based funding to assist in the most cost-effective way to manage our regional waterways.
''This way we can target those hot spots that need immediate attention through applying science-based data, investing resources and funds more wisely, to understand and ultimately alleviate the worst affected areas,'' outgoing national president Dr William Rolleston said in a statement.
