7. Housing—KiwiBuild Official Advice and SupplyHon MICHAEL WOODHOUSE (National) to the Minister of Housing and Urban DevelopmentHousing—KiwiBuild Official Advice and Supply7. Hon MICHAEL WOODHOUSE (National) to the Minister of Housing and Urban Development: Does he agree with all official advice provided to him on the KiwiBuild programme; if not what advice does he disagree with?Hon PHIL TWYFORD (Minister of Housing and Urban Development): Thank you Mr Speaker. I receive a variety of advice on KiwiBuild some of which I agree with and some of which I don't agree with. It's important that there's a flow of free and frank advice from officials as the Government develops its plans to develop affordable housing for young Kiwi families.Hon Michael Woodhouse: In that case does he disagree with the advice provided to him by the Ministry of Business Innovation and Employment (MBIE) that KiwiBuild despite his modest projections of 16000 over the next three years will at best only deliver 8000 and Treasury's advice that half of that would come from the existing pipeline?Hon PHIL TWYFORD: I do disagree with that.Hon Michael Woodhouse: Why is the Minister so sure that the development sector will be able to respond to his projections of 16000 houses in the next three years when Treasury the Reserve Bank MBIE and a number of independent bank economists can find nothing in Government policies to suggest that that goal is even remotely achievable?Hon PHIL TWYFORD: I have been open that initial advice from Treasury and MBIE didn't tally. I got officials into my office and went through the details of the policy and as a result of that Treasury reported in its half-yearly update a $5.4 billion cumulative investment in residential building over and above the normal investment by the private sector. A programme that is as large and ambitious as KiwiBuild places inevitable pressures on the Public Service and I'm comfortable in allowing them the time necessary to get up to speed with our ambition.Hon Michael Woodhouse: Was that the same update wherein Treasury said that the ramp-up of construction of 10000 houses per annum will be slower than signalled by Government and the net increase in 2022 will be only 4500 because 2700 were already factored in with the Crown building programme and 2800 will be purchased from existing private sector development?Hon PHIL TWYFORD: I disagreed with Treasury's earlier advice that KiwiBuild would deliver only half the number of houses projected in the early years due to offsetting against the private sector because of industry constraints. I don't believe that Treasury at that point adequately took into account our policies designed to alleviate those constraints but by the time of the half-year update Treasury noted in the update that there were policies designed to alleviate those constraints that would include construction work visas to increase labour supply infrastructure funding prefabricated and modular housing designed to increase productivity potentially through the addition of foreign construction firms and buying off the plan to alleviate finance access issues.Hon Michael Woodhouse: Did those discussions with officials include the Minister's promised 12 to 15 developments the size of Hobsonville that will be simultaneously constructed and where and when will those developments take place?Hon PHIL TWYFORD: That will take a little longer.Hon Michael Woodhouse: I seek leave to table two documents—I can do them together or separately. One is an Official Information Act (OIA) response dated 29 January to the National leader's office from the Ministry of Business Innovation and Employment on KiwiBuild numbers and an OIA request response to the National leader's office from Treasury dated 30 January 2018.SPEAKER: Just before I seek the leave I want to check with the Minister whether those papers have followed the proactive approach of release that his colleagues are following. No they haven't. Is there any objection to them being tabled? There appears to be no objection. They can be tabled.Documents by leave laid on the Table of the House.
