Waitaki District Council (WDC) ) intends to release a procurement opportunity for the fabrication and placement of concrete tetrapods along the seaward face of the Oamaru Harbour Breakwater. This initiative is part of Council’s long-term strategy to protect critical coastal infrastructure and heritage assets from escalating erosion and wave damage.

The project will involve the production of tetrapods at the former South Hill landfill site, selected for its proximity to the harbour and suitability for heavy equipment operations. The installation of these structures will:
• Dissipate wave energy
• Stabilize existing rock armouring
• Slow ongoing erosion and degradation

This work builds on previous successful installations and aims to enhance the breakwater’s resilience, reduce long-term maintenance costs, and safeguard the harbour’s operational and cultural value.
