Just over 25 per cent of the island’s main ring road, from Pokoinu to Rutaki, will be involved in the scheduled programme, which will involve trench excavation, cable laying, and road reinstatement.
Trench excavation will be conducted down the lagoon side of the main road.
There are also significant stretches where digging in the road lane will be required due to the nature of side-paving and paths.
“TAU’s project is a necessary one and is being coordinated and scheduled in advance of the anticipated road upgrade planned for Puaikura - attempting to minimise disruption to services, businesses, residents and public,” a spokesman for the electricity utility said.
In January the road through Muri was excavated before Christmas as part of TAU’s cable-laying programme. The trenches were backfilled after the work was complete but bad weather caused potholes and left the carriageway almost impassable in places, prompting TAU to apologise.
The wet weather then gave way to hot and dry conditions, causing a dust problem.
There were also complaints that a section of the back road at Muri had been damaged by a traffic detour.
