1.2.2 Effects Ratings and Definitions
An outline of the effects ratings and definitions used in this assessment is provided in the Boffa
Miskell: Natural Character, Landscape and Visual Effects Assessment Methodology (11
February 2019) attached as Appendix 1. In summary, the significance of effects identified within
this assessment are based upon a seven-point scale which includes very low; low; moderate-
low;
filtering, while for the weasel data set 141,825 SNPs were retained. Given the
different sizes of the two data sets and the filtering parameters that are affected by
sample size, these numbers may not reflect the relative genetic diversity of these two
species accurately. However, it appears that weasels have considerably more genetic
variation than stoats in Taranaki. All quality metrics for each SNP were high, with the mean

enables the Council to continually re-evaluate its approach
and that of 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 holders,
this report also assigns a rating as to each Company’s
document containing your answers, please refer to the document name and the relevant
page number in the text box.
Give full details of the source of the discharge and any
treatment it will receive prior to discharge:
These details are provided in sections 3 and 5 of the attached
Assessment of Environmental Effects.

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. As was the case for the 2021-2022 year, the rates of application in 2022-2023 raise questions about
whether the ability of pasture to take up nitrogen could be or is being surpassed. On the other hand, the
timing and volume of irrigation events in 2022-2023 suggest that these inputs were being managed more
intentionally as a
to help fund this network.
Affordability is both a local, regional and national issue. Therefore, new tools, such as time and location-
based charging to manage demand, are not just welcomed – they are necessary.
The current funding system based on Fuel Excise Duty (FED), Road User Charges (RUC) and rates is under
extreme pressure. The local government sector wish to work with the Ministry of Transport and NZTA in a
collaborative process to investigate and implement a
level of environmental
performance and compliance for 878 (87%) of a total of 1007 consents monitored through the Taranaki
tailored monitoring programmes, while for another 96 (10%) of the consents a good level of environmental
performance and compliance was achieved. A further 27 (3%) of consents monitored required improvement
in their performance, while the remaining one (<1%) achieved a rating of poor.
In terms of overall environmental and compliance performance by the consent holder over
under consent conditions and this showed that daily
volume limits and instantaneous abstraction rates were complied with for the majority of the monitoring
period. Self-monitoring of the Inglewood discharge showed that the discharge generally complied with
consent conditions.
During the year, NPDC demonstrated a high level of environmental and administrative performance with the
resource consents.
For reference, in the 2020-2021 year, consent holders were found to achieve a high level
