A new report shows a Taranaki landfarm, where oil industry waste is disposed of, was being so poorly run the regional council was forced to intervene and the contractor running the landfarm was removed.
The report reveals that during the 2011-13 monitoring period the Waikaikai landfarm was badly mismanaged.
Oil industry waste on the landfarm wasn't being stored correctly and the council was not receiving important information it required from the landfarmer.
Green Party candidate for New Plymouth Sarah Roberts says it's the second damning landfarming report in a month and questions why the practice is allowed to continue.
She says two of the 12 landfarms in Taranaki have been shown to have significant difficulties adhering to consent conditions.
"This is a huge prime agricultural area where we are competing with the oil and gas industry and the dairy industry side by side. We want to protect our clean, green image and this is not the way to go about it."
Last month another report revealed livestock on the Manutahi landfarm were standing in paddocks on top of untreated oil industry waste.
Taranaki Regional Council says it's completely opposed to livestock being exposed to untreated oil industry waste. The Ministry for Primary Industries says it's up to farmers to manage the risks.
At a regional council meeting this week it was disclosed the Manutahi landfarm had again breached its resource consent conditions relating to spreading oil waste.
