other site, GND2252 (Waverly – Whenuakura
aquifer), was found to have experienced a slightly declining trend in water level over its recent data
record. In addition to these sites, there were others where statistically significant rising (4 sites) and
declining (2 sites) trends in water level were identified. None of these trends were however deemed
environmentally meaningful, given the extremely low rate of annual change (+/- <0.1%).

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
approach to
Council for monitoring of groundwater abstraction was installed
in September 2014. The new system showed that the instantaneous volume limit was breached
frequently by small amounts, although the daily limit was met, with one exception. The Company
has applied for a higher instantaneous abstraction rate in the consent replacement process.
In September 2012, the Company commissioned a 20.7 ha extension of the irrigation area, and a
further extension of 6.0 ha became operational in January 2013.

expectations remain high.
Strong financial position
The Council finished the 2015/2016 year with a surplus of
$963,000 (total comprehensive income). Expenditure was
$373,000 over budget, in large part due to the Council
providing unbudgeted emergency funding to assist those in
need following the severe winter storm damage. Overall it
was a good result, noting that general rates increases have
been at or below the rate of inflation for the past few years.

to minimise the generation of wastewater, but this could be further improved.
The discharge of wastewater into the Kahouri Stream did not cause any recorded impact on
the macroinvertebrate communities of this stream, and the impact on water quality was
minimal. However, discharge rates to the Kahouri Stream need to be reduced to ensure a 1:100
dilution. The irrigation of wastewater was undertaken with no significant adverse effects on
the environment, but further improvement regarding
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.
Evaluation of environmental and administrative performance
Besides discussing the various details of the performance and extent of compliance by the Trust, this report
also assigns a rating as to their environmental and administrative performance during the period under

Ngāti Rangi decision observed that not following Port Gore when assessing the effects of a
proposal in the context of that case would be to “lock in” hydro-electricity water takes and flow rates
for as long as the controlled activity status was retained, thereby preventing adverse effects from
being avoided or mitigated.10 In support of its finding, the Court highlighted the
