Canterbury Regional Council warns farmland could be flooded if foothills and alpine rivers rise today.
It said erosion from recent flooding had weakened some river areas and high currents today were likely to cause further damage.
The Ashburton River may overflow, although the Opihi is expected to remain within its capacity.
The council said it would monitor vulnerable areas.
In Auckland, dozens of flights have been canceled or delayed due to fog for the third morning in a row.
