Sorry, wasn't intending to hide anything. James Hardie was behind one of the crap systems of cladding I believe. Poorly treated timber from Carter Holt has been fingered, and a multitude of building development companies that created new legal entities for each new development, then folded them at the end of each job and vanished into the night. This was a standard practice. And of course, the government (starting with Nationals Bolger, and subsequent governments too) through weakening regulation, and local government who failed to ensure that even the weakened laws were followed. Like all good mistakes - everyone had a hand in it, and no one group was entirely responsible.
Edit: On further thought, I see I've been slightly misleading/unclear. When I started taking about the manufacturers of the problems, I wasn't meaning just the building materials that have failed, I also meant the regulatory systems and practices that were poor.
