The approval for the extension of world-first anti-erosion technology for southern Wairarapa has been labelled a “magic bullet” to maintain crucial road connection on the isolated coast.
The newly approved resource consent by Greater Wellington Regional Council would allow South Wairarapa District Council to extend its EcoReef along the South Wairarapa coast.
Constructed out of interlocking hexagonal blocks filled with aggregate, it replaced boulders that frequently washed away.
The council applied for the consent last year after the May 2025 storm devastated the road at Whatarangi.
Since its initial trial in 2022, EcoReef had reduced damage from erosion along the Cape Palliser coastal road from severe swells, the council said.
The first two trial EcoReefs were placed at Whatarangi and Turners Bay.
Two new structures would be built at Pūtangirua Pinnacles and Te Kopi.
EcoReef reduced damage from erosion along the Cape Palliser coastal road from swells and severe weather.
South Wairarapa councillor and Infrastructure Committee chair Colin Olds said he hoped the extensions would provide strong protection against rough sea conditions along Cape Palliser Road.
“This road is enormously important to the local community and wider region for cultural, economic, and social reasons.
“It is crucial we do what we can to protect the road so residents and visitors can continue accessing and appreciating this significant and spectacular corner of Aotearoa.”
Olds said that some sections of the road to Cape Palliser were prone to 4-metre swells, as well as sea level rise.
“EcoReef will be, hopefully, the magic bullet that solves the problem so that communities out there can maintain transport to and from Cape Palliser.”
