Bay of Plenty Civil Defence said river levels in the region were high but none had flooded.
"The ground and river catchments will already be saturated, so the Bay of Plenty Regional Council flood team will be keeping a close eye on things.
"There may be surface flooding in towns - take care driving and make sure kids avoid the rivers- they're pretty wild just now," Civil Defence said.
"We are also expecting more high winds- take care around trees because their root systems may have been weakened by all the rain. Now's a good time to clear leafy gutters and drains around the house and move any outdoor furniture."
