Environment Canterbury flood managers are monitoring the current heavy rainfall.

The agency said it is “reasonably confident that while there will be surface flooding in low areas, it doesn’t expect out-of-river flooding from this weather.”

Adjacent landowners are advised to monitor the rivers and consider shifting stock stock from vulnerable areas.
