Flooding is one of the most significant hazards in Waimakariri.
The Waimakariri River, one of New Zealand’s major braided rivers, has a long history of flood events and requires ongoing flood protection and management.
Flooding can occur after prolonged rainfall, river surges, or coastal storm events, affecting low‑lying areas, river terraces, farmland, and residential zones close to waterways.
As our climate changes, we expect to see average temperatures increase. The warmer atmosphere will hold more moisture so rainfall is predicted to increase and we will see more frequent heavy rainfall events.

Flood protection in Canterbury
Regional flood protection includes stopbanks, riverbank strengthening, and ongoing maintenance, but no system can remove all risk.
Environment Canterbury is responsible for reducing the impacts of flooding in Waimakariri.
It’s important for anyone living near rivers, streams, or the coast to understand their local flood zones and be prepared for evacuation during major weather events.
