Environment Southland Tightens Flood Bank Grazing Controls

Environment Southland has adopted new rules requiring farmers to get approval before grazing stock on flood banks during winter months.

The new Flood Control and Drainage Management Bylaw introduces stricter controls on stock grazing between June 1 and August 31, when wet conditions increase the risk of damage to flood protection infrastructure.

Environment Southland Chair Jeremy McPhail said the winter grazing change reflects the increased risk of damage to flood banks during the wetter months.

"Flood banks and floodways are part of our region's essential flood infrastructure network. In winter, when the ground is softer, stock can cause pugging and track damage. This weakens these community assets over time. Requiring prior approval between June and August will help manage that risk while still working with landowners on practical solutions," Chair McPhail said.

Grazing would still be possible during winter months, but farmers must seek approval first.

"This is about making sure flood protection works are in the best condition possible ahead of heavy rain events. Where grazing can be done without compromising a flood bank, we want to enable that in a way that's clear and consistent," he said.

The bylaw also clarifies Environment Southland's ability to carry out urgent maintenance and emergency repairs without prior authority, and establishes clearer mapping of council-owned flood control works.

Other changes include setting 20 working days as the standard timeframe for processing applications, creating a public register of approved activities, and restricting tree planting, building construction and material storage within floodways.

Farmers needing approval can contact Environment Southland or find application forms at es.govt.nz. The bylaw takes effect from Monday, May 11.

Seventeen submissions were received during public consultation earlier this year, with 14 submitters speaking at hearings in March and April.
