Preservation arguments are raging in Christchurch right now, which makes this very interesting clip from the documentary Hometown Boomtown from NZ On Screen all the more pertinent. It examines the major changes to Wellington's cityscape (many of them made in the name of earthquake strengthening) in the 1970s and 1980s, includes interviews with many of the major players of the time (including Bob Jones and then-mayor Sir Michael Fowler), and has heaps of amazing demolition footage. Worth a look!
