These definitions and explanations should provide a comprehensive understanding of key terms related to freshwater management in New Zealand. Keep in mind that the management practices, regulations, and terminology can evolve over time.

National Environmental Standards (NES)Nationally applicable regulations that set standards for specific activities, including those related to water management.
NitrogenDischarge of contaminants into a water body from a single fixed point, such as a pipe or drain (eg, from the likes of sewerage, factory, and dairy shed outfalls). Managing point source discharges involves regulating and treating the release.
Non-point source dischargeNitrogen is a nutrient that can encourage the growth of nuisance aquatic plants. These plants can choke up waterways and out-compete native species. High levels of nitrogen in water can be a result of runoff and leaching from agricultural land. Ideally, total nitrogen levels in waterbodies should be less than 0.5 grams per cubic meter to prevent excessive growth of nuisance plants
National Policy Statement for Freshwater Management (NPS-FM)Diffuse discharge of contaminants from multiple sources, makes it challenging to trace the exact origin. Managing non-point source discharges involves mitigating runoff.
Outstanding freshwater bodyA water body of exceptional ecological, cultural, or recreational significance. Managing outstanding freshwater bodies involves special care and protection.
PermitsAn activity is allowed without requiring a resource consent if it complies with the stipulated conditions, usually because it has minimal environmental impact.
Permitted activitySets out the government’s objectives and policies for managing freshwater resources in New Zealand and provides direction about how local authorities should carry out their responsibilities for managing freshwater.
pHA measure of the acidity or alkalinity of water. A very high or very low pH means that water can be unsuitable for aquatic life. The pH range that is suitable for aquatic plants and animals is 6.5 to 9
PhosphorusPhosphorus is a nutrient that can encourage the growth of nuisance aquatic plants. These plants can choke up waterways and out-compete native species. High levels of phosphorus in water can be a result of runoff from agricultural land. Ideally, total phosphorus levels in water should be less than 0.04 grams per cubic metre to prevent excessive growth of nuisance plants
Point source dischargeDiffuse discharge of contaminants from multiple sources makes it challenging to trace the exact origin. Managing non-point source discharges involves mitigating runoff.
Poorly drained soilsSoils with inadequate natural drainage. Proper management is essential to prevent waterlogging and associated issues.
Profile Available Water (PAW)The amount of water available for plant use in the soil profile. PAW assessments inform water allocation decisions in agricultural settings.
Public notificationThe process of informing the public about resource consent applications. Public notification allows stakeholders to provide input on proposed activities.
QualityThe overall condition of a water body, including its chemical, physical, and biological characteristics. Monitoring and managing water quality is essential for ecosystem health.
QuantityThe amount of water (eg, flow) in a given area or time period. Managing water quantity involves allocation, conservation, and avoiding overuse.
