The Horizons Regional Council emergency management team will keep a close eye on the weather over the long weekend.
The staff met on Friday to discuss the weather warning in place for parts of the region.
While Horizons' river modelling does not forecast any significant flood events in the major catchments, staff are ready to respond if required.
Horizons chief executive Michael McCartney said he appreciated that those who experienced flooding prior to Christmas might feel anxious with rain on the way.
