METSERVICE ISSUES UPDATED WARNING FOR COASTAL PARTS OF DUNEDIN AND WAITAKI.
Alert: 06 Jul 2026
Latest updates and information on: otagocdem.govt.nz
Flooding and snow affect Otago region
A State of Emergency has been declared for Waitaki. Many road closures in Dunedin and Clutha. Snow affecting Central Otago.
Red warning for coastal Dunedin and Clutha
Metservice is advising Otago residents living in low lying coastal areas in Dunedin and Clutha to expect between 80 to 120 mm of rain from noon today until 9am Monday 6 July. Other nearby areas could be impacted too, and snow may complicate the situation.
ORC monitors rainfall, lake levels and river flows. Using MetService forecasts along with our own data and expertise, we model the predicted effects of heavy rainfall.
Lake flooding is typically slower to develop compared to high river flows, meaning we usually have more time to issue updates and warnings.
Our water monitoring sites are automatically updated through the day and night. These are publicly available, and you can view the data.

ORC undertakes monitoring and analysis to forecast how lakes and rivers will respond to heavy rainfall, which enables other agencies like city and district councils, power companies, and (if necessary) civil defence to plan their responses. We have a 24/7 flood duty officer, and a wider flood management team for these situations.
ORC also ensures that pump stations and flood protection schemes are unobstructed and working as intended. ORC’s Lower Clutha flood scheme protects 9,300 hectares of land from inundation in high river flows.
While lake flooding is usually able to be monitored more than flash flooding from rivers, you should still remain prepared for a natural hazard event.
GetReady has helpful information on what you can do to stay safe before, during and after a flood.
