Episode Details

The Awakino Gorge on State Highway 3 that connects Waikato to Taranaki will be closed for nine nights as of tonight. Every time there's a major storm it seems Karangahake Gorge between Paeroa and Waihi is closed. It was closed for five days this month. The Waiwera Gorge is open, then closed, then open, then closed. The Brynderwyns are a constant worry. Is it time to revisit our national highways and accept that what might have worked in 1923 —widening a dray track into a road— is not really fit for purpose in 2026?  

Sticks of gelignite blasting away through the Karangahake Gorge worked fine in 1875, but if you've driven through the gorge recently, looking like a goldfish with one eye out the side looking at the rock face, praying it stays up, the other goldfish eye looking out at the river and the road and hoping there's no landslip, you wonder how long these gorges are going to be drivable and whether it's worth patching them up, opening them, patching them up, opening them, patching them up, opening them. Round and round and round we go. We don't seem to be advancing. It's just spending hundreds of millions to stay in place.  

Transporting New Zealand says we have to start thinking about plan B when it comes to the transport network. They say when the Awakino Gorge is closed, it costs the sector up to a million dollars per day in additional travel time, fuel consumption, and vehicle operating costs. Transporting New Zealand, in the case of the Awakino Gorge, has suggested developing a 20km windy metal road, and suggested a one way route north for a couple of hours, then opening it for a couple of hours to the south. Which sounds like it would have been a brilliant thing to do in 1952, but in 2026, is that really the way to go when we're trying to connect two major provinces, two major exporting provinces, Taranaki and Waikato? I wouldn't have thought so. The New Plymouth mayor says he would sue NZTA if he could for their successive failures over the years, which have cost the people of his region millions and millions of dollars.  

Are our road networks still fit for purpose? Does it make sense to keep going over the same roads that were initially, in many cases, horse tracks, then dray roads, then roads for the old Model Ts? It worked back then. They made it work. And back then it was rip, shit and bust, hoots wahay, let's just blast our way through, and the quickest way to get anywhere is in a straight line between two points. Given the precarious state of the climate, given that the extremes are becoming the norm when it comes to the storms, the landslips, the torrential rain, do we need to redraw the map rather than keep retracing over existing lines?
