Twyford PhilPHIL TWYFORD (Labour—Te Atatū): Before I was so rudely interrupted I was saying that I think this is a debate worth having because there is clearly a difference between certainly our side and the National Government benches on this question. The Minister for Building and Housing referenced the Productivity Commission he referenced the experience in Christchurch but curiously he did not reference the situation in Auckland where not only are we falling dismally behind in supply and the deficit has accumulated the 42000 dwellings that the independent hearings panel estimates has built up on the Minister's watch not only has supply been such a signal failure but also affordability has been a disaster. We can see that today with the average dwelling in Auckland—not just old Auckland City but across the entire amalgamated city and the Auckland region—now costing $1 million.It is an absolute disaster. There is no affordability. We desperately need more affordable housing and I suspect that the Minister is among the kind of dewy-eyed optimists who think the unitary plan by injecting some greenfield land into the system and upzoning to allow more density in the city is automatically going to deliver big gains in affordability. There is a lot of smart money and a lot of urban land economists and others who are highly sceptical about that contention and do not believe that on its own it is likely to go anywhere near what is needed in terms of increasing the volume of supply. That is why—because urban land markets are so imperfect and because for example there are demand pressures in the real estate market—under this Government's policy settings are unchecked and there are vast amounts of foreign money flooding into the real estate market. There is a whole system of tax policy and incentives that encourage the investment of massive amounts of capital in real estate speculation under this Government.So because those things are all in place because we have this massive accumulated deficit in the number of dwellings that are needed and we will have for a long time to come—in fact the Minister's own officials say that the deficit of dwellings in Auckland will not be eliminated before 2030. That is the advice of Ministry of Business Innovation and Employment officials released to Labour under the Official Information Act. The Minister denies it—I know he does not want to hear because it is bad news for him—but that is the fact and that is why Labour believes that measures like inclusionary zoning and being able to require a percentage of affordable dwellings is the sensible thing to do. If we care about affordability if we care about making homeownership and in fact renting affordable we need to be willing to intervene in the market to market to make that happen. We cannot wait until some great nirvana decades into the future when we have a perfectly functioning urban land market. That is certainly not going to happen on this Minister's watch. People cannot afford to wait.We need affordable housing and that is why I think Metiria Turei has very sensibly put up Supplementary Order Paper 210 which would require a prescribed percentage of affordable dwellings and must include a percentage of dwellings to be available for sale at a price equal to or below the price that is 4 times the median household income in that area." Four times the median household income—I think the Minister would probably agree with that. He would agree that that is a worthy goal. His eyes are going from side to side—I am not quite sure how to interpret that—but I think based on the Minister's previous comments he would agree that four times the median household income is a good thing. That is why my amendment that is on the Table would require that all future special housing areas—and it would be prospective not retrospective—that would be enacted under the 3-year extension in this bill would be required to have a percentage of affordable dwellings.The Minister agreed to that. He agreed to the principle of exclusionary zoning—that is a quota of affordable dwellings. He agreed to that in the sweetheart deal that he negotiated with Auckland iwi in the wake of his vacant Crown land fiasco. If it is good enough to put a quota of affordable homes—"
