High Quality Content by WIKIPEDIA articles! The implosion of Radio Network House on 5 August 2012 was New Zealand`s first ever controlled building demolition by explosives. Like most other buildings in the Christchurch Central City, Radio Network House was damaged beyond repair in the 22 February 2011 Christchurch earthquake, and the Canterbury Earthquake Recovery Authority (CERA) added it to the demolition list in August 2011. In July 2012, it was announced that the building was going to be imploded, involving a specialist company from America with a large track record for this type of work. The right to push the button for the implosion was put up for auction on the TradeMe website, and became the auction with the third highest page views ever. The winning bid of NZ$26,000 was made by a consortium of demolition contractors, who allowed the Child Cancer Foundation to nominate a six-year-old boy from Queenstown to trigger the event. The implosion, which was carefully monitored to assess the suitability of this approach for potential future applications, went without any problems and it is anticipated that this will have paved the way for many more implosions in New Zealand in general, and in Christchurch in particular.
