Because what we do know from the initial briefings by the Ministry of Social Development (MSD) is that there is an expectation that, as we restrict people going on to New Zealand super, some migrants who need income support will end up going to a main benefit. While that number may be slightly lower, there's higher operational costs to going from New Zealand super to a main benefit, due to just the complexity of the welfare system. I note that the initial briefing by MSD also notes that, in the longer term, the projected savings of this bill to super—and this was before the Supplementary Order Paper was introduced—are likely to be even lower now. It's only 0.3 percent of the projected cost of New Zealand super.
