effects emanating
offsite. The final marine Ecological Survey also confirmed that over time there had been
nothing to suggest the activities undertaken at the site had caused an adverse effect in the
specific analysed areas.
While the legacy issue still remains, given the absence of measurable adverse effects and less
than minor offsite effects the Environmental performance has been rated as ‘Good’ rather than
‘Improvement required’.
Administrative performance was rated as high.

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 Mann-Kendall test. Further justification for this statistical approach can be found in
Stark and Fowles (2006).

biodiversity outcomes that can
be realised when they are absent or present only in low numbers. Mustelids predate on
fledglings. Research confirms that, in mustelid trapping control areas, the survival rate of
native bird fledglings increases by up to 10 times. In the case of the bellbirds, the
survival rate of fledglings increased from 8% (without trapping) to 80% (with trapping).
Mustelids are also likely to have a similar impact on the survival rates of other native
species of interest to this

This guide has been specifically developed for Taranaki and addresses storage ponds only. This
reflects changes in effluent management from traditional treatment ponds (with discharge to
water) to effluent holding ponds (with irrigation to land).

of environmental and administrative 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 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

classes for each FMU).
Although indigenous forest is the dominant land cover in the upper sections of the Southern Hill Country
and Northern Hill Country FMUs, the proportions of stream reach graded in band A appear relatively high
considering that the geology and terrain in both of these FMUs are particularly prone to high rates of
sediment erosion. It should be noted that there was limited available monitoring
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.

adjacent receiving waters were recorded in late summer-autumn under low flow conditions
during the monitoring period (at which time the Waverley system had been desludged with
bio-bugs, the Manaia system had been upgraded with the addition of two wetlands, the
Kaponga pond subsurface discharge rate was very low and receiving water dilution very high)
in early winter under higher flow conditions (when the Patea upgraded ponds system
discharged continuously),

generally allowing gravel extraction from river and lake beds to minimise river aggradation
subject to the rate of extraction not exceeding the rate of gravel recharge, and
increased protection of wetlands to arrest their ongoing decline and incremental loss.
