There's also an issue of the coastal ships themselves. New Zealand only has a few dozen of these ships, and most of them are specialist vessels that carry products like cement from port to port. That takes thousands and thousands of the equivalent truckloads off the road. But it does mean that we are heavily reliant on these ships as part of our supply chain. Some of the companies that provide these shipping services have bought new ships recently, in the past few years. These ships have a 30- to 40-year asset life.
