ART ATTACK OVER DAIRY FARM POLICY

The bust of New Zealand Environment Minister Nick Smith, sculpted as a protest by artist Sam Mahon, attracted 112 bids.

Mr Mahon said he made the sculpture to protest at what he considers is Mr Smith's too-soft stance on pollution created by dairy farms.

Mr Mahon gathered cow dung from an organic dairy farm, ground it in a coffee grinder, mixed it with a polymer resin and pressed it into a mould.

He polished the sculpture with beeswax to create a finish that resembles bronze.
