Flood protection in Bay of Plenty
Major rivers and coastal lowlands mean river, drainage and coastal flooding can interact across the Bay of Plenty. Heavy rain in steep upper catchments may take time to move downstream, so local weather alone does not tell the whole story.

Understanding flood risk in Bay of Plenty
Tauranga, Western Bay, Rotorua, Whakatāne, Kawerau, Ōpōtiki and rural river plains each face different combinations of river, surface-water and coastal risk.
Rangitāiki, Whakatāne, Kaituna and other major river systems
Confirm the site-specific exposure through council mapping, local observations and professional advice where required.
Stopbanks, floodwalls, floodgates, pumps and drainage schemes
Confirm the site-specific exposure through council mapping, local observations and professional advice where required.
Coastal lowlands, estuaries and high-tide interaction
Confirm the site-specific exposure through council mapping, local observations and professional advice where required.
Use the Flood Room and local hazard information together. Check whether a site sits inside or behind a river scheme and whether water could accumulate on the protected side.
Planning for people, places and continuity
Schools and early learning
Account for nearby streams, open drains, coastal access and school transport routes. Make barrier deployment an early, trained action—not a last-minute response.
Iwi, marae and community facilities
For marae and community facilities, protect safe gathering space, kitchens, sanitation, electrical services and culturally important items without obstructing evacuation.
Councils, businesses and organisations
Kiwifruit, forestry, port, retail and public facilities should identify critical operations, hazardous materials and alternate access before forecast heavy rain.
Official Bay of Plenty flood information
Use official warnings first, then regional monitoring and hazard information. Live readings can be provisional or interrupted during severe weather.
Prepare before water reaches the site
Use flood maps, LIM information, past events, drains, contours and site photos.
People first, then critical entrances, services, records, stock, plant and continuity functions.
Choose the forecast, gauge level or on-site observation that starts deployment.
Assign roles, label equipment, time the setup and review after every exercise or event.
Portable flood protection options
A doorway, garage, loading bay and whole-site perimeter do not need the same solution. Expected depth, flow, ground surface, width, corners, storage, deployment time and drainage behind the barrier all influence the choice.
A continuous barrier line can be configured around vulnerable areas.
Dry-weather training helps teams deploy safely and consistently.
Turn Bay of Plenty flood information into a site plan
Send Special Solutions Flood Protection photos, measurements and what you know about how water reaches the property. We can help identify a practical starting point for a home, school, marae, council site or organisation.
