A latest EcoReef® coastal protection structure has been successfully completed at Te Awanga, designed to help safeguard the lagoon and nearby infrastructure from erosion and storm damage. The structure was installed in just five weeks, placing up to 65 blocks per day – even with tidal challenges. The EcoReef® system now spans 210 metres along the beach, directly in front of the lagoon – an area that plays a key role in Hastings District Council’s stormwater network.
The need for a resilient solution became clear during Cyclone Gabrielle, when the coastline came within three metres of breaching the lagoon. Hastings Mayor Sandra Hazlehurst acknowledged the importance of the project, describing the EcoReef® system as a practical response to a growing environmental challenge.
The structure is comprised of 1,385 hexagonal EcoReef® blocks, designed to interlock and hold natural beach material in place. Most of the time, it’s barely visible – buried beneath the sand and gravel – but during storm events, the lower layers are exposed, helping to absorb wave energy and prevent erosion.
Local resident Roy Boonen, who helped pitch the EcoReef® concept to Council, said the community was thrilled with the outcome. “Everyone is delighted that action has been taken and that we have such a cool, unique structure that works with nature to provide the protection that’s needed,” he said.
Manufactured locally by Lattey Group and installed using materials sourced from the site, the project aimed to reduce transport emissions, while maintaining beach access and keeping disruption to a minimum for the popular local surfing and dog walking spot.
