Delayed report shows need for clean water rules
A new report showing the poor health of New Zealand’s lakes demonstrates why we urgently need clean water rules to
protect our waterways, the Green Party said today.
“Almost a third of all lakes in New Zealand are unhealthy, and many are getting worse,” Green Party Co-leader Dr Russel
Norman said.
“New Zealanders love our rivers and lakes, and we want to protect them. Our kids have a birthright to swim and fish in
our waterways, but this legacy is at risk.”
Dr Norman was commenting on Lake Water Quality in New Zealand 2010, a report by the National Institute of Water and Atmospheric Research (NIWA). The report was due to be released by the
Ministry for the Environment last week, but was held back until today.
“One can only speculate about the reasons for the delay,” Dr Norman said.
“It is interesting timing that the report’s release was delayed during the World Dairy Summit in Auckland, when the
report concludes that pastoral land use is associated with the ecological deterioration of our lakes.
“This report is further evidence that we need clean water rules to set standards, limits, and targets for water quality
as soon as possible.”
Based on monitoring of 112 lakes between 2005 and 2009, the report’s authors projected that nearly a third of New
Zealand’s 3820 lakes are unhealthy. They also make clear conclusions about the cause: “The most significant finding from
this study […] is that pastoral land use in New Zealand is associated with eutrophication and ecological deterioration.
Furthermore, the condition of some lakes currently in good condition is declining, likely as a result of nutrient
enrichment from livestock farming.”
Dr Norman said New Zealand’s rivers and lakes were bearing the ill effects of agricultural intensification and
industrial dairying.
“It’s time we took action to turn this around by introducing clear rules for clean water.
“In many areas, the situation is getting worse. Between 2005 and 2009, twice as many lakes were deteriorating as were
improving.
“This report provides yet more evidence that we urgently need clean water rules. The water measurement regulations
announced today are a start, but they are well short of what’s needed.
“Not only did John Key’s Government sit on this report, it’s sitting on a draft National Policy Statement (NPS) on
freshwater management. This is ready to go and would set clear targets and timelines for improving the state of fresh
water in New Zealand.
“The Land and Water Forum reported that we need an NPS, and quickly. This report shows there is no more room for delay.
“We need clean water rules and we need them now,” Dr Norman said.
