1.0 INTRODUCTION
This report summarises earthquake occurrence and ground deformation in Taranaki for the
period 1 July 2018 to 30 June 2019. It compares the location and rate of earthquake
occurrence in the last year with recorded activity post-1994 and also examines the ground
deformation data. These are used in assessing the quiescent state of Taranaki volcano.
2.0 EVOLUTION OF THE SEISMOGRAPH NETWORK
The Taranaki Volcano-Seismic Network was
privilege to be your Regional
Councillor for the last six years and also Chair of
the Policy and Planning Committee.
If re-elected, I'll continue to advocate for our rivers being clean
for swimming and our natural habitat thriving; ensuring we
protect and grow our region.
I'll also focus on public transport, prudent rates and resource
management.
I bring a range of experience.

18. Mr Chapman stated that TBP has recently made improvements to the irrigation
system including an upgrade to a three pump system and the replacement of timers
on the irrigators to ensure more careful management of the discharge. It was also
explained that frequent sampling of treated wastewater is undertaken by TBP and
measured at an independent water testing facility in order to

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
