Coastal management

We have several action plans in place for different areas of coastline around the Coromandel.

We're lucky to have some of the most beautiful and pristine beaches in New Zealand, if not the world, on the Coromandel Peninsula, that's why we've adopted an ambitious programme to work with all stakeholders to manage the effects of climate change.

Our beaches are one of the major reasons for people coming to visit and live here. But keeping them in such magnificent condition comes at a cost, given the effects of climate change, storm events and other natural processes.
In 2018, our Council adopted the Coastal Management Strategy, which sets out a range of initiatives we will be taking over the coming years to better manage our coastal assets and understand the risk of coastal inundation and coastal erosion. The 2018-2028 Long Term Plan includes $2.6 million over three years to help us implement this strategy. You can read more about our Coastal Management Strategy below.

Shoreline Management Plans - help us with our journey towards sustainable coastal communities

Following on from the adoption of our Coastal Management Strategy and Coastal Hazards Policy in 2018, our Council is now developing Shoreline Management Plans (SMPs). This is a three-year project to  define the flooding and erosion risks to people and the social, cultural, economic and natural environment across all parts of our coastline over the next century and beyond.

As we develop these plans, we have a valuable opportunity to understand our coastal environment more holistically, including the connections between people, catchments and waterways, landscapes, estuaries and beaches.

Coastal Management Strategy

In 2018, our Council adopted the Coastal Management Strategy, which sets out a range of initiatives we will be taking over the coming years to better manage our coastal assets and understand the risk of coastal inundation and coastal erosion. The 2018-2028 Long Term Plan includes $2.6 million over three years to help us implement this strategy. 

This approach to coastal management activity ensures a district-wide approach, allowing us to better-manage our coastline from a holistic and long-term perspective. We work together public and private organisations such as the Waikato Regional Council, New Zealand Transport Agency (NZTA), the Department of Conservation, iwi and community groups with an interest in coastal protection.

‘Coastal management’ encompasses a wide range of projects to identify hazards and risks and develop Shoreline Management Plans to combat these, with a view to building ‘resilient’ coastal communities.

The CMS was adopted by Council in June 2018. You can download the strategy on the top right-hand-side of this page.

Council adopts revised climate change assumption for Long Term Plan

In February 2018, our Council adopted the Government's revised climate change guidance based on forecasting assumptions the Ministry for the Environment published in December 2017.This means a potential sea-level rise of up to 1.88m by 2150 will be taken into account for all major infrastructure projects adopted as part of our Council's 2018-2028 Long Term Plan. You can read more about this here.The document 'Coastal Hazards and Climate Change Guidance' for Local Government 2017 is available from the Ministry for the Environment website.

Coastal Hazards Policy

Our Council adopted the Coastal Hazard Policy on August 7, 2018. This policy sets out our approach to sustainably managing the effects of coastal hazards on our district's coastal foreshore.

Coastal project updates

We’ve been underway with several high-priority, reactive coastal projects over the last few months of 2018. Brief updates on these are provided below.

Thornton and Ngarimu Bays
The Thornton and Ngarimu Bay coastlines, damaged by erosion during the January 2018 storm, have been re-instated using sand push-ups from the beach. We are working with NZTA to explore ideas for the longevity of the Thames Coast Road in this area, and there is community interest in Thornton for improving the carpark and surrounding area ahead of this summer.  We will continue to engage with community groups with a view to finding a mutually-acceptable solution.

Thames Town Coastline
Damage occurred along our Shortland Wharf to Moanataiari walkway has been re-instated. Thames is one of the strategic locations in our District that would benefit greatly from Shoreline Management Plan (SMP) along a 'Dynamic Adaptive Pathway Planning (DAPP) action plan.

• Tararu
Recovery from the January storm continues in this community.

Works have been completed at Wilson St and are planned for Robert St to re-instate coastline damage from the storm. We have worked with the Tararu South Flood Protection Group to facilitate the repair between the two streets which has now been completed.  We continue to meet with the community as part of the SMP development. The Group is very active and has been for about 20 years, and is currently fund-raising for proposed rock revetment works on their private frontage. It is a fantastic example of how the local community, in liaison with our Council, is on the 'journey to become a resilient community' from coastal hazards.

• Flaxmill Bay and Cooks Beach
A combination of king tides and an extreme weather event in July caused significant erosion at Flaxmill Bay and Cooks Beach. Appropriate coastal protection management structures, hard and soft engineering options, are being considered. Environmental changes have raised the community’s awareness of the need for careful management of the coastline, and in particular our foreshore, a series of public drop-in meetings and workshops have been held to share information with residents.

November-December 2018: Our coastal engineer discussed options to curb beach erosion at Flaxmill Bay with approximately 40 Mercury Bay south residents. TCDC had already lodged a resource consent application with Waikato Regional Council for a rock wall that will transition to a backstop wall and, ultimately, into a soft option (dune plantings) to curb the erosion. Our Council will also be lodging an application for a trial groyne to be constructed at Flaxmill Bay, with the exact location and material to be determined.  All going to plan, construction of the rock wall/backstop wall and the groyne should start by early 2019.

November 2018 - an aerial survey was undertaken of the Thames Coast to help in management of this shoreline. We engaged a contractor to undertake drone photography in this area, using Council reserves for taking off and landing. The contractor was required to comply with all Civil Aviation Authority rules and has completed the work. Further aerial surveys for other coastlines is likely to be carried out during 2019.

June 2018: Our Council adopted its Coastal Management Strategy. You can find out more about this here
