Road workers are shoring up the coastal road in Vaimaanga to prevent it eroding into the sea.


Infrastructure Cook Islands and private contractors are building a coastal protection wall where the road, particularly in front of the Sheraton, has been flooded by big waves.

Project manager Robert Heather Junior said this would protect vulnerable underground utility services, as well as private properties and the main road itself. They have all been affected by erosion related to storms and high seas.

Heather promised “a robust, safer and more resilient road network to assist with the … social and economic development of Rarotonga and the Cook Islands”.

During this work, motorists can expected road disruptions. Heather says temporary speed restrictions and lane closures will be put in place as part of required site safety and traffic management.

“We appreciate the public’s understanding during this time.”

The Environment Impact Assessment on the project has been approved with conditions the project team has to adhere to, says Heather.

Seventy metres of rock wall was completed in April/May this year, and a further 50-metre extension of the rock wall is to be completed this month.
