Environment Southland produced a major report on nitrate pollution in Southland’s groundwater which showed worsening levels at most sites they monitor. The report blames "intensive farming, notably dairying and winter grazing of dairy cattle."
ES sent copies in advance to Fonterra, dairy giant Open Country and DiaryNZ. ES refer to these groups as "stakeholders". Then they tried to bury the report without making any fuss, bunging it in an online portal with no press release.
Luckily, the ODT found it.
Despite nitrate pollution being a major public health issue, ES didn't alert either Te Whatu Ora (Health NZ) or WellSouth because "they did not have any contacts."
Clumsy cover-up... meet gross incompetence.
As @phil_stevens said earlier, Environment Southland is the poster child for regulatory capture in NZ.
