Christchurch Harbour

Warning no longer in force

There is no longer a threat of flooding, though standing water and debris may still remain.
Coastal conditions are expected to improve and no flooding is expected. Tides remain high.
We will continue to monitor the situation and will issue further alerts or warnings if necessary.
If you have been evacuated only return to your property once the emergency services have advised that it is safe to do so. Never drive through flood water, just 30cm of fast flowing water is enough to move your car.
