The Government dissolved the BIA (Building Industry Authority, the Government department which was responsible for the oversight and administration of the building sector) on 30 November 2004 and replaced it with DBH (Department of Building and Housing). Some of the Acceptable Solutions to the Building Code were re-written, most notably E2/AS1 External Moisture which covers the detailing of roofs and walls was greatly expanded. The Standard covering durability of timber framing was amended in late 2003 with the publication of NZS 3602: 2003 Timber and Wood-based Products for Use in Building. This revision required a return to the use of treated radiata framing in external walls. Several thousands of homes throughout the country are still awaiting renovation, with a total cost that has been estimated by a PricewaterhouseCoopers report to the Government in 2008 as being around NZ$11.3 billion for a "consensus estimate" of 42,000 buildings. Other building experts estimate the true cost at $23 billion for 89,000 buildings, and accused government of reducing the figure of affected buildings to 42,000 buildings because they were allegedly "unhappy" with the expert prediction. The majority of affected buildings are homes or apartments, but in 2011 the twenty-year-old Ronald McDonald House for children with cancer and their families at Wellington Hospital was demolished as leaky and replaced. The Minister of Education said in 2009 that at least 73 schools were affected, and in 2011 that 157 schools still needed repairs, at an estimated cost of at least $1.5 billion As of 2013 the Ministry of Education was taking action against architects and builders involved with 87 of the 309 schools which have "leakiness" problems. One school in Wellington, Seatoun School, built at a cost of $5.3 million and opened in 2002 is costing $4.5 million to repair. As of mid-2009, plans for an up to NZ$6 billion bailout package shared between government and local authorities are in doubt because the amount could affect New Zealand's international credit rating. In November 2009, the National government decided not to offer a more substantial sharing of costs, and it is now estimated that in most cases, around 64% would have to be borne by the owners, 26% by Councils, and only 10% by government funds, while also forcing homeowners to sign away their rights to sue for more. Prime Minister John Key noted that while claimants did not have to accept the settlement, legal costs for bringing suit could eat up any further money awarded to them.
