Irrigation NZ welcomes policy statement for freshwater

Irrigation New Zealand (INZ) generally welcomes the government's National Policy Statement for Freshwater Management (NPS) and National Objectives Framework (NOF). INZ agrees that New Zealand's fresh water needs nationally consistent, better, more direct and clearer policy to ensure it is sustainably and effectively managed for the benefit of all.

"By having national bottom lines and allowing for regional and local circumstances, the NPS and NOF will prevent situations where unrealistic conditions are set on water quality for irrigation schemes," says Andrew Curtis, INZ CEO. "Having everyone work off the same page will mean that resource consent processes will be less onerous and less time and money will be wasted reaching acceptable outcomes."

INZ is pleased that the updated NPS seems to have broadened its measures of water quality and now requires a fuller understanding of issues which impact a body of water before setting limits. "The NPS now suggests that biotic indicators such as the Macro-invertebrate Community Index (MCI), should be included as performance measures - this is a good thing," says Mr Curtis.

INZ believes that if community freshwater values, as now set out in Appendix 1, are to be realised, attention needs to be paid to an inclusive range of factors such as pest management, habitat restoration, sediment loads, as well as nutrients, to maintain and improve river health. "There are many examples around the country which show how habitat restoration alongside stock exclusion and phosphate management have created thriving rivers - despite relatively high nitrate levels - such as the Wakakahi stream in south Canterbury," says Mr Curtis. "New Zealanders need to understand maintaining and improving water quality is complex and can be achieved in many different ways - sticking a number on it and regulating everyone to this does not achieve outcomes," he says. Additionally, INZ believes that the exceptions provisions may pose a future risk and looks forward to greater clarification. "Healthy waterways are the responsibility of both urban as well as rural New Zealand, and we must face New Zealand's water quality challenges as a nation. Farmers are not solely responsible for issues with waterways and should not be picked on to solve these problems on their own."

INZ is committed to finding a way for New Zealand to develop sustainably managed irrigation schemes within acceptable environmental limits. "Water is our most valuable renewable resource and we believe that irrigation in New Zealand is essential to protect against climatic variations and to enhance the country's ability to feed its population and to contribute to feeding the world," says Mr Curtis.
