I see in this article that Optus is considering the installation of a DSL based video-on-demand delivery network, because the incumbent, Telstra, is not moving along.
This sort of pressure on the roll-out of services can only happen with an unbundled local loop!
It's taking the newcomers a little while to get up and running, but it shows the lie of the NZ Telecom argument that unbundling doesn't add much in the way of choice. ("Only a small percentage of lines are affected").
It obviously adds competition, and even if Optus don't go ahead, the threat will be enough to get Telstra moving.
