Stock Exclusion Regulations

The overall Stock Exclusion Regulations came into effect on 3 September 2020, but the rules contained within it will come into effect over a period of time up until 1 July 2025 depending on the stock type and slope of land.

The Stock Exclusion Regulations outline national rules that apply to the exclusion of stock from waterways.

Dairy, dairy support and beef cattle, pigs and deer must be excluded from wetlands, lakes and rivers with a bed greater than or equal to one metre wide.

Minimum setbacks of three metres between stock and the bed of a lake or river will be required, except where permanent fences or riparian planting is already in place to exclude stock. Setbacks from wetlands are not defined in the stock exclusion regulations but should take wetland requirements in the NES-FW into consideration, including controls on land disturbance and vegetation clearance within 10m of a wetland.

For farmers considering wider setbacks to provide for more riparian values, the Landcare Research report ‘Riparian setback distances from water bodies for high-risk land uses and activities’ (2020 - link below) provides guidance on recommended setbacks based on different functions of riparian areas, including for sediment and nutrient management, improving bank stability, and improving water quality and biodiversity values/

Dairy, dairy support and beef cattle, and pigs must not cross lakes and rivers more than twice per month unless by way of a dedicated bridge or culvert (except for where this in impracticable due to a highly mobile bed). Where stock are crossing waterways (in accordance with the rules) they must be actively driven through the water.

Dates for compliance vary according to stock type and terrain.

Stock Exclusion from rivers and lakes:
  • 3 September 2020 – for dairy, dairy support and beef cattle, pigs and deer in new pastoral systems (where the grazing of the pastoral system commenced from/after 3 September 2020)
  • 1 July 2023 – for dairy cattle and pigs on all slopes, and for beef cattle and deer break feeding, grazing annual forage crops or irrigated pastures.
  • 1 July 2025 – for dairy support cattle on all slopes, beef cattle and deer on low slope land. See the interactive map for stock exclusion(external link)
Exclusion from wetlands (applies to all dairy, dairy support and beef cattle, pigs and deer):
  • 3 September 2020 – for dairy, dairy support and beef cattle, pigs and deer in new pastoral systems (where the grazing of the pastoral system commenced from/after 3 September 2020)
  • 1 July 2023 – exclusion from natural wetlands identified in an operative regional plan, district plan or regional policy statement as at 3 September 2020
  • 1 July 2025 – exclusion from natural wetlands more than 500m2 in area on low slope land or any natural wetlands that support a population of threatened species. Councils are required to map these wetlands under the National Policy Statement – Freshwater Management.
Use of bridges/culverts for stock crossings (applies to dairy and dairy support cattle, and pigs):
  • 1 July 2023 – for dairy cattle and pigs
  • 1 July 2025 – for dairy support cattle
