Environment Canterbury Chair Deon Swiggs says teams have been working around the clock to monitor conditions and help keep communities safe.
“Events like this are a reminder of the important work that happens behind the scenes to reduce flood risk across Waitaha Canterbury. Our flood protection and drainage network plays a critical role during severe weather, and I’d like to thank our staff and partner agencies who are monitoring conditions and responding where needed.
“For those affected by the weather, please take care, stay up to date with the latest information. Be careful on roads and always avoid driving through floodwater.”
Stay up-to-date with weather warnings and advice
Staff met with MetService, Civil Defence and partner agencies over the weekend and again this morning to share updates on river conditions and flood risk across the region.
People are encouraged to keep an eye on MetService forecasts and information from their local council and Civil Defence, which are the primary sources of emergency information during severe weather events.

River mouths opened naturally in South Canterbury
Despite significant rainfall overnight in the Waimate district, the Waihao, Saltwater Creek and Opihi river mouths opened naturally without the need for mechanical intervention.
Southern Duty flood controller Blair Poulter says teams have been working through the night to monitor conditions and respond where required.
“After a period of heavy rain, the challenge is often what comes next. The ground is already saturated in many areas, so even relatively light rainfall can lead to rapid rises in waterways and localised surface flooding.
“Our teams are monitoring conditions closely, checking key assets and working with partner agencies to understand what’s happening across the catchments.”
