What we don't want to do is create a system of tradable licences, effectively, where people can relocate a service well away from where it is at the moment; 10 kilometres, if you think about it in the context of the Hutt Valley, that's still quite a large area that a service could relocate within. So that service could relocate from Melling to Naenae, for example, and still be within 10 kilometres—which wouldn't be the intention.
