quality criteria. Irrigation of wastewater during the year led to mass loadings of
nitrogen per hectare that were well in excess of those recommended by the Council and the description of
N loadings previously provided by RNZ. The rates of application in 2021-2022 raise questions about
whether the ability of pasture to take up nitrogen could be surpassed, and the timing and volume of

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
receiving environment from the activities during the monitoring year.
Administrative performance is concerned with the Contact Energy’s approach to
demonstrating consent compliance

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

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).
