The increase in the proportion of farmland used for dairying was most pronounced in
Canterbury and Southland.
The report notes that climate change is already affecting New Zealand’s land systems and
that we can expect ‘severe effects on land and human systems from long-term changes and
increased frequency of intense rainfall events.’ Some of the effects noted in the report include
changes to the suitability of land for horticulture and
potential that during rainfall runoff will pick up small amounts of hydrocarbons
and silt due to the nature of the activities on site;
• Stormwater which collects in the area surrounding the drilling platform and
ancillary drilling equipment. This stormwater has a higher likelihood of contact
with potential contaminants, particularly drilling mud;
• Produced water which flows from the producing formation and is separated
from the gas and liquid phase at the surface; and
• Drill cuttings,
kōura (freshwater crayfish) were a
staple harvest with large numbers of kahawai and pātiki (flounder) also caught on the river mouths along the
Taranaki Iwi coastline. Although access to many of the age old fishing spots for piharau has become a
challenge, many are still caught in the months of June, July and August by Taranaki Iwi families.
Relatively high rainfall up on the mountain quickly drains through these river systems, contributing to high water

Council’s Director-
Environment Quality, Gary Bedford. “The coastal sites look
even better.”
He says that while the word ‘swimmability’ rolls easily off
the tongue, the concept is fraught with complications and
questions. “A river in full flood and laden with debris after
heavy rainfall could never be sensibly regarded as
swimmable, no matter what the bacteria levels may be.”
He also says it’s important to note that E. coli are simply an
indicator of a potential risk

Well worth pond-ering
The dry start to 2015, followed by a brief spell of intense rainfall in
early February, highlighted the importance of sound dairy effluent
management practices.
“We’re finding a few common pitfalls that can lead to non-compliance
with dairy effluent discharge consent conditions during abnormally dry
or wet weather,” says the Taranaki Regional Council’s Compliance

Uncertainty is a component of any freshwater monitoring or modelling. For example, river flows and levels
fluctuate throughout the day, and nutrient levels will vary depending on how much rainfall and runoff is
occurring. Pathogens and algae will grow in response to a range of factors, such as temperature, light and
river flow. This uncertainty is described in terms of ‘confidence’. For example, how certain it is that water
quality is
