Residents on the Otago Peninsula are being urged to exercise extreme caution on the roads on Friday morning.
Slips and surface flooding have closed Portobello Road and parts of Highcliff Road. Power was reportedly earlier disrupted to about 200 customers.
Three Mile Hill Road between Dunedin and Mosgiel is also closed.
Meanwhile, the Lower Taieri and Silverstream rivers appear to be coping with overnight rainfall.
The Otago Regional Council says they look to be receding.
Both rivers were monitored on Thursday night in case they broke their banks.
The council earlier warned residents in eastern parts of Otago to prepare for possible flooding.
However, it now says rainfall overnight was steady rather than heavy and the level of both rivers looks to be receding.
