The first building to be demolished by implosion in New Zealand has come down this morning in Christchurch's CBD.
The earthquake-damaged Radio Network building hit the floor in seconds when it was imploded at 8am this morning.

Sixty-three kilograms of explosives were detonated by six-year-old Queenstown boy Jayden Halliwell.
He was nominated the honour by the Child Cancer Foundation after eight demolition companies bid $26,000 on TradeMe for the right.
A series of loud bangs could be heard before the 14-storey building came down in a cloud of smoke, watched by hundreds from behind a public exclusion zone.
The Christchurch Earthquake Recovery Authority said if this implosion is successful other buildings may be demolished the same way, because it is faster and cheaper.
