Hon CARMEL SEPULONI: When we talk about medium to long term, generally we're talking about a three- to five-year programme of work, but we also recognise that change and improvements to the welfare system will need to continue to be ongoing. We're not going to get to the end of a work programme and look at our welfare system and think it's perfect. Any Government that's in place will need to continue to improve the way in which we support some of New Zealand's most vulnerable people.
