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 environmental and administrative performance.
Environmental performance is concerned with actual or likely effects on the receiving
environment from the activities during the monitoring year. Administrative

A 20 year timeframe provides the required certainty to
enable the upgrades to be investigated and undertaken
over time.
The proposed plant upgrades are aimed at improving the
effluent quality while remaining cost effective for the
rate payers. There is no requirement for upgrading the
plant capacity.
The timeframe of the upgrade stages are based on
economic considerations. The upgrades proposed are:

Electricity
There are two levels of connectivity for the Taranaki
electricity network:
The high voltage national electrical transmission
system that covers both North and South Islands.
This system connects generation sources to local
substations and is operated by Transpower. The
Taranaki region connects at Stratford to the
National Grid through 220 kV circuits that run north
to Huntly and south-east to
determined using the p value (p < 0.05 = significant).
When multiple correlations are undertaken, there is a chance that some will be found
to be significant purely by chance. In order to deal with this potential problem, the
Benjamini-Hochberg False Discovery Rate (FDR) method was applied to the results
of the Man-Kendall test. Further justification for this statistical approach can be
found in Stark and Fowles (2006).

1.1.4 Evaluation of environmental and administrative performance
Besides discussing the various 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
rating as to each Company’s environmental and administrative performance during
the period under review. The rating categories are high, good, improvement required and poor for both
environmental and administrative performance. The interpretations for these ratings are found in
Appendix II.
For reference, in the 2021-2022 year, consent holders were found to achieve a high level of environmental
performance and compliance for 88% of the consents monitored through the Taranaki tailored
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.
