Gisborne Civil Defence is advising Tolaga Bay residents to avoid the coastline, with swells expected to rise to up to 4.5m around the area.
Boat users are advised to stay off the water and residents are being warned to stay away from Tolaga Bay wharf with waves reported to be crashing over it.
Civil defence said high swells were also causing minor coastal erosion in and around the Tairāwhiti region.
The high swells are expected to continue tomorrow with waves potentially reaching 6m.
