State Highway One, the main route in and out of Northland could be completely closed at the Brynderwyns for months for maintenance, starving the region of much needed visitors and income. A group of local businesses has already described the state of the roads in the region as an "economic barricade" to its potential. This will be an actual barricade on State Highway One. Waka Kotahi's board will make a decision on the recommended recovery and rebuild work this month but the agency is already planning detours and says it will work around key dates like Waitangi and Easter. Independent research released last month puts the cost of closures on the Brynderwyns at tens of millions of dollars. North Power chief executive, Andrew McLeod, speaks to Lisa Owen. In a statement Waka Kotahi says confirmed detour routes and closure dates will be advised next month following usual internal processes and approvals. It says it will engage with partners, stakeholders and the community to ensure the work is carefully planned to minimise disruptions as much as possible. A business case for long term resilience options is still being considered, alongside the proposed recovery and rebuild works. As this is unfunded, long term resilience options will follow our standard business case processes.
