period 1 July 2017 to 30 June 2018. It compares the location and rate of earthquake
occurrence in the last year with recent historical activity and also examines the ground
deformation data. These are used in assessing the quiescent state of Taranaki volcano.

The Taranaki Volcano-Seismic Network was commissioned by the Department of Scientific
and Industrial Research in late-1993, with the first usable data being recorded

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
consent holders to resource 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.
1.1.4 Evaluation of environmental 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
sustainable development of the
region’s resources.
1.1.4 Evaluation of environmental 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. The rating categories are high, good, improvement required and poor for both
environmental and administrative performance. The interpretations for these ratings are
considered responsible resource utilisation, to move closer to achieving sustainable development of the
region’s resources.
1.1.4 Evaluation of environmental and administrative performance
Besides discussing the various details of the performance and extent of compliance by the Company, this
report also assigns them a rating for their environmental and administrative performance during the period
under review.
Environmental performance is concerned with actual or likely effects on the
average. Base diagram source: IPCC.
Temperatures measured at climate stations across the
region show marked increases in air, water and soil
temperature, particularly over the past decade. Changes
in river water temperature are more subtle, while air and
soil temperatures have risen sharply, with soil temperature
increasing at a rate of around 1.4°C per decade. Changes
over 10 to 15 year periods are affected by long-term climate
trends as well as changes due to shorter

Committee and as convener of the SH3 Working Party, the
Council worked with the New Zealand Transport Agency as
various options were considered for the $245 million
improvements to SH3 at Mt Messenger and Awakino Gorge.
Strong financial position
The Council finished the 2016/2017 year with a surplus of
$1.6 million (total comprehensive income). Expenditure was
$568,000 under budget. Overall it was a good result, noting
that the general rates increases have

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%).
