Kohimarama Beach seawall protection

Auckland City Council has completed the $6 million project to return Kohimarama Beach to its pristine best. The beach now features an 800m strip of sand 5m to 15m in width at high tide.

Nearly 50,000 cubic metres of imported sand now provides beach goers with recreation space at all tides, and guarantees the seawall's protection. The once sandy strip of beach was gradually depleted over the last few decades, exposing the seawall protecting Tamaki Drive. The seawall suffered substantial structural failure.

The long-term solution selected to address the problem was to replenish the beach with imported sand. This provided separation between the high tide and the seawall. The sand was dredged from at least three kilometres off the Pakiri coastline, then transported by barge to Kohimarama where it was pumped onto the beach. Disruption to traffic along Tamaki Drive was minimal for this project as all sand was moved via a sea route and pumped ashore.

In addition to the sand replenishment:

new headland structures constructed on the west and east ends of the beach contain the sand and divert stormwater away from the beach
combined and extended stormwater pipes and outlets under the beach now ensure the safe discharge of stormwater
the boat ramp opposite Neligan Avenue is extended and vastly improved.

Physical works began in late February 2004 and were completed in September 2004.

The new beach was officially opened on Saturday 18 September 2004.
