The illegal open-air burning of toxic demolition materials from Northland College has seen two parties receive steep fines.
Auckland-based Yakka Demolition and Kaikohe farmer Jason Robert Bill were sentenced to more than $50,000 in fines and costs for their roles in disposing of the materials more than two years ago.
Material including plywood, medium density fibreboard, treated timber, painted wood, chipboard, plastic, metals and coated wire were dumped and went up in smoke on Bill's land in April 2016 and August 2017.
Both parties pleaded guilty to two charges each laid by the Northland Regional Council in the Environmental Court and were sentenced recently.
In the sentencing notes, Judge JA Smith said Yakka's charges related to burning demolition waste and the discharge of waste containing contaminants. Bill was charged with ''permitting contravention, permitting a discharge of contaminants from open burning'' in August 2017, and permitting the discharge of contaminants on to land.
