Environment Waikato is to prosecute Tracker Demolition Landfill Ltd following a fire at a Pukemiro landfill in February.

The fire involved a pile of tyres, and a pile of construction and demolition waste next to it, which burned for several weeks. Oil had to be contained from the site, with smoke affecting neighbours for more than a month.

The company is to be charged with discharging contaminants to land, air and water, both in relation to the fire and ongoing waste stockpiling and disposal at the site.
