Taranaki’s Forgotten World Highway and Surf Highway will receive government funding to replace two essential culverts to strengthen the region’s transport links and economic resilience, Regional Development Minister Shane Jones and Transport Minister Chris Bishop say.
A total of $7.5 million from the Regional Infrastructure Fund will go to fixing the Toko Stream Tributary Culvert on SH43 (Forgotten World Highway) and Whenuariki Stream Culvert on SH45 (Surf Highway).
Mr Jones says the investment, of $2.5m for SH43 and $5m for SH45, reflect the Government’s commitment to fix regional infrastructure.
“Culverts may not be sexy, but they are essential to keep our community links intact. The Forgotten World Highway is an important route for regional communities, tourists, and businesses. They need infrastructure that is fit for purpose,” Mr Jones says.
The Toko Stream Tributary Culvert is estimated to have only two years left in it and is so damaged that if it fails, the state highway could be closed, resulting in a 50km diversion.
“Transport infrastructure is critical to the success of our regions. This investment will help ensure communities remain connected and businesses can continue to move people and goods efficiently,” Mr Bishop says.
The century-old, hand-dug Whenuariki Stream Culvert on the Surf Highway has already experienced a partial collapse and erosion is progressing toward the highway. A failure could result in major disruption, with heavy vehicles facing a 133km diversion.
“This project is a good example of why proactive investment matters,” Mr Bishop says.
“The Whenuariki culvert has reached the point where replacement is the most sensible long-term solution. By acting now, we’re reducing the risk of major disruption to road users and ensuring the Surf Highway remains a reliable route for years to come.”
Mr Jones says regional communities need infrastructure that supports economic activity and keeps people connected.
“We know the regions want investment that delivers practical results, and that’s exactly what this project does. Replacing these ageing assets will help improve network resilience, support local businesses and keep those connections throughout coastal Taranaki.”
Design and consenting work on the culverts is expected to begin within six months with construction expected to begin in 2027.
Editors’ note:
The Regional Infrastructure Fund invests in infrastructure that supports economic growth, strengthens resilience, improves regional productivity, and helps unlock investment opportunities across regional New Zealand.
These projects were selected based on delivery readiness, regional need, resilience and safety benefits, and their ability to progress to design and consenting in the next six months.
