During the year, NPDC demonstrated a good level of environmental and high level of administrative
performance with the resource consents
For reference, in the 2020-2021 year, consent holders were found to achieve a high level of environmental
performance and compliance for 86% of the consents monitored through the Taranaki tailored monitoring

During the inspection undertaken on 26 June 2024, it was noted that significant volumes of red sand-
blasting garnet was present under zones 11 and 12, as well as around both roadside stormwater drains
underneath the pipe rack. The inspection was carried out following rainfall and it appeared that the large
volume of stormwater had washed the garnet and associated contaminants towards, and probably into, the
stormwater collection system. Staff onsite advised that recent works carried
rainfall events and display a greater range of seasonal water level variation than
the region’s deeper aquifers. In general, groundwater levels across the region appear
relatively stable; however five sites are displaying statistically significant trends in water
level change. Three of these sites display positive trends, meaning water levels are
increasing at these sites. The remaining two sites, GND0508 (Taranaki volcanics aquifer) and
GND0708 (Whenuakura aquifer) display negative trends,
allocated across FMU-A and FMU-B. All other aquifers
have insignificant volumes of water allocated (≤1 % of estimated sustainable yield). It is not foreseen that
there will be any increases in groundwater demand in the short to medium-term that would be sufficient
to place groundwater resources under any significant allocation pressure.
As would be expected, monitored groundwater sites display fluctuations in water level as a result of
seasonal variations in rainfall recharge. The
other than in exceptional circumstances, is
workable and can be implemented in the majority (but not all) cases with moderate ease
and minimal cost in respect of being able to utilise existing pond storage systems.
• Those farms with high rainfall and large catchment areas and or high risk soils will struggle
to implement a solely land based effluent irrigation system and in some cases will never be
able to meet the requirements of land only application
