MattR: Don't get too excited. I came home one day to find this next to our driveway. It was for new copper :(
I think you could be right there; I may have come to the wrong conclusion. Although there were a couple of Chorus vans, I've since realised that I haven't seen any trucks from the local fibre company (HFS; the company that actually does the physical fibre work). It may indeed just be new copper :(
