So there is a question mark over the costs of bringing these systems together. I don't see anywhere a cost-benefit analysis, which the ACT Party would like to ask the Minister in the next section on: what is the Government Statistician going to need to make this happen? What is the IT spend that's needed to integrate this? Maybe we'll hear this in the Budget on Thursday, but I suspect it's a significant amount of money to bring researchers and statisticians into a place where they can actually, with permission from the public, match up data that is relevant.
