Hawke's Bay drainage firm Santo Drainage and Contracting Ltd has been fined $12,555 for illegally burning plastic waste in Hastings.
It's the largest fine handed down for illegal burning in the region in a case brought by the Hawke's Bay Regional Council.
A charge was laid under the Resource Management Act 1991, after the large fire was lit on Lyndhurst Rd, Frimley, on May 1.
Court documents show an employee started a large fire and burned treated timber, plastic pipe, general plastic products, plastic hose, cement culverts, wire and coated metals including a galvanised flue.
The "clean-up" fire was instigated at the direction of the company and its director, Terrance Santo.
