A child with cancer will be the one to push the button and implode Christchurch's Newstalk ZB building.
Seven demolition companies joined forces to bid $26,000 for the right to choose who'd be the one to set off the explosives this Sunday.
They passed the opportunity to the Child Cancer Foundation.
The 14-storey building is expected to take just 7.7 seconds to come down.
