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

The discharge of cooling water recorded an increasing ammonia concentration throughout the monitoring
period, though the impact to the Inaha stream was minimal. The thermal effect of the plant discharges were
within the thermal limits for the duration of the monitoring year. The abstraction of surface water and
groundwater was undertaken within compliance standards for the duration of the year. The dilution rate for

1.1.4 Evaluation of environmental and administrative performance
Besides discussing the various details of the performance and extent of compliance by STDC, this report also
assigns a rating as to STDC’s environmental and administrative performance during the period under review.
Environmental performance is concerned with actual or likely effects on the receiving environment from
review can be summarised by the following main points:
Surface soils across the site are dominated by semi-porous silty clay-loams, overlying more
impervious clay soils
Soils below 2000 mm have not been characterised
Chloride concentrations in the soil beneath the irrigation zone are highly elevated compared
to non-irrigated areas
The shallow groundwater table is in direct connection with semi-porous loamy silty-clay
Due to high rates of irrigation loading, shallow
showed that all daily volume limits and instantaneous abstraction rates were complied with.
During the year, NPDC demonstrated a high level of environmental and administrative
performance with the resource consents.
For reference, in the 2015-2016 year, 71% of consent holders in Taranaki monitored through
tailored compliance monitoring programmes achieved a high level of environmental
performance and compliance with their consents, while another 24% demonstrated a good
level of

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 Trust’s approach to
demonstrating consent compliance in site operations and management including the timely provision of
information to Council (such as contingency plans and water take data) in accordance
