A Christchurch building owner is contemplating seeking an injunction for the implosion of Radio Network House - but officials say his concerns are unfounded.
The 14-storey building will be taken down with explosives next Sunday unless the owner of the Westende building stops the proceedings.
He's worried about air pollutants and seismic movement.
However, Ceres operations manager Mark Frame says it's not going to be an issue.
"It's the same amount of dust pollution that would come off any demolition, including the building demolition that's happened about a metre away or right next door to the building that's been going on for a few months."
Mr Frame says the land movement would be similar to a large truck driving past the building.
Meanwhile the auction to press the detonation button on Radio Network House has soared to $30,000.
The TradeMe auction to sell the rights to press the button was set up as a fundraiser as part of the Isaac Theatre rebuild - with the Government promising to match the final figure for the Christchurch Heritage fund.
A Canterbury trader known only as 'roloff' has the top bid.
The auction finishes next Wednesday at 6:05pm
