Hon GRANT ROBERTSON: That is a very, very good question, and I don't have the answer for it today, but it does relate to the way in which the Ministry of Social Development's systems work. There is a very, very large number of people involved, and when we are changing supports, that, in turn, triggers other changes to other assistance that they might be getting as well. So it's complex but it has been one of the issues that, over my time as a Minister, I have sought answers on because I do believe that when Governments make policy changes, we should be able to implement them as soon as possible.
