details of the performance and extent of compliance by the Company, this
report also assigns them a rating for their environmental and administrative performance during the period
under review.
Environmental performance is concerned with actual or likely effects on the receiving environment from the
activities during the monitoring year. Administrative performance is concerned with the Company’s
approach to demonstrating consent compliance in site operations and management including the
measures
of the state of biodiversity. Some of these provide assistance in determining progress since the
renewed focus on biodiversity in the late 1990s.
Key conclusions are:
Although the rate of loss of indigenous forests has slowed considerably, it has not stopped
entirely. Between 1996 and 2012, New Zealand lost a further 10,000 hectares of indigenous
forests.
Of the six categories of indigenous vegetation monitored, five declined in area between
1996 and 2012
values, including
proposed changes to the Freshwater Plan.

Relationship between habitat loss and species
loss
The loss of habitat is a forerunner to species
extinction.
Figure 13 shows that with initial decreases in
habitat area (upper right hand curve), the rate of
the rate and daily volume of
the groundwater abstraction might exceed that of the permitted activity (Rule 48).
Rule 49 provides for groundwater abstraction to be undertaken as a controlled
activity, subject to two conditions:
• The abstraction shall cause not more than a 10% lowering of static water-level by
interference with any adjacent bore;
• The abstraction shall not cause the intrusion of saltwater into any fresh water aquifer.
Todd Energy Limited holds water permit 6971-1 to
surrender. Paddock 22 was found to have been landfarmed after a second
sample was collected. This contrasted with the consent holder’s records.
During the year, the consent holder demonstrated a good level of environmental performance and an
improvement is required for administrative performance with their resource consents. An overall good
performance rating was awarded, this was downgraded from a high due to the impact that was noted on
the biological communities. The grading of the

abstractions for the Motukawa HEP scheme. This site requires flow gauging on each
sampling occasion for rating purposes.
Site Mangaoraka Stream at Corbett Road
This site is representative of a northern Taranaki ringplain stream, (but with its
source outside the National Park), draining an agricultural catchment. The site is also
a hydrological recording station. It is located

The most improvement in long term water quality has been illustrated in the Waingongoro River at SH 45,
with significantly improving trends in DRP and total phosphorus, and with reduction in nitrate and total
nitrogen by slightly less than the rate defined as significant. This improvement has been coincident with
land-irrigation of a major industrial (meatworks) discharge since 2001 and the diversion of Eltham’s WWTP
discharge out of the river since 2010.
Significant deteriorations in black disc clarity were recorded at two sites, one of which
reflected historical erosion events in the headwaters.

consent holders to resource management and, ultimately, through the refinement of
methods and considered responsible resource utilisation, to move closer to achieving
sustainable development of the region’s resources.
1.1.4 Evaluation of environmental performance
Besides discussing the various details of the performance and extent of compliance
by the consent holder/s during the period under review, this report also assigns a
rating as to each Company’s
