- Summary
- Tauranga Harbour is a large, micro-tidal, barrier-enclosed estuarine lagoon, located in the western Bay of Plenty. The harbour comprises multiple headlands, inlets and islands and is protected by a large barrier island, known as Matakana Island. Shorelines throughout the harbour can be broadly classified into three different morphological types: Consolidated cliffs and banks (e.g Motuhoa Island) Unconsolidated shorelines (e.g Pilot Bay) Low-lying estuarine areas (e.g Matua salt marsh). Tonkin & Taylor Ltd (T+T) were commissioned to undertake the coastal erosion hazard assessment and have partnered with the National Institute of Water and Atmospheric Research (NIWA) who have conducted the coastal inundation assessment with hydrodynamic modelling. The coastal erosion assessment provides Coastal Erosion and Instability Hazard Areas (CEIHA) for 32 selected sites around the harbour.
