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
pump stations (all due to high rainfall and power outages during Cyclone Dovi in
February 2022), and a further 14 reticulation overflows (the majority of which were due to high rainfall or
blockages due to fat and/or wet wipes). This total of 23 unauthorised incidents is similar to the previous two
monitoring periods.
During the year, NPDC demonstrated an overall high level of environmental and administrative compliance
and performance with the resource consents related to NPWWTP

moderate temperatures and regular rainfall, but when the rainfall is heavy it can
cause flooding and landslips. In periods of low rainfall, the region can experience droughts. In some parts
of the region, and at certain times of the year, storms and tornadoes are a reasonably frequent occurrence.
Coastal erosion
Coastal erosion is the retreat of the shoreline caused by water currents, waves, and wind. It is a natural
process that can be influenced by human activity. The Taranaki coastline

Climate change is expected to exacerbate soil loss and present challenges to the future
management of erosion-prone land. It is estimated that extreme storm events resulting in
flooding and slips are likely to occur somewhere in Taranaki about once every five to six
years. In coming years, the region is expected to experience more frequent and intense
heavy rainfall events, increasing both the frequency and
