Farmers
On grazed parts of the farm, bush trees
rarely occupy a large percentage of
paddock area. They often remain on parts
where stock don’t graze much, on account
of steep contour or difficult access. So
fencing trees off may make little difference
to the length of time that stock can be
grazed in a paddock. A fence may actually
make grazing management easier,
excluding stock from parts that are difficult
to muster, and concentrating them where
pasture growth is greater, but perhaps not

conditions setting out the requirements that the Company must satisfy in order to minimise
risk of damage to the environment or overuse of resources. Consent 0822-1 expired during the
monitoring period (12 March 2012) and was renewed as 0822-2 on 29 November 2012 with a
number of changes to the conditions. Consent 3400-2 was varied on 18 June 2012 to include a
condition allowing an increase in the use of the chemical ‘Spectrus CT1300’ to control

monitoring year, with most
commencing irrigation in November or December and concluding in February. Rainfall recorded at the
Council’s monitoring locations over the summer irrigation period ranged between 55 % and 111% of
historical mean values. A particularly dry November and December lead to a drought being declared in
Taranaki during 23 December 2017. As a result, irrigation water demand was high during the 2017-2018
irrigation season, with a total water use across all exercised irrigation
use, or the ability of the receiving formation to accept injected fluids. The results of
groundwater quality monitoring undertaken show no adverse effects of the activity at monitored locations.
Inspections undertaken during the monitoring year found sites being operated in a professional manner
and there were no Unauthorised Incidents in relation to any of the Company’s DWI consents.
During the year, the Company demonstrated a high level of environmental and administrative performance
consents to discharge water or sediment into the Makara,
Mangaotea, and Mako streams, one consent to discharge wastes to land around Lake Ratapiko
and four land use permits for bed disturbance and structures in the Manganui River,
Mangaotea Stream and Lake Ratapiko. Seven additional consents allow Trustpower to abstract
water, and construct and maintain structures in the Mangaotea Stream.
During the period under review, Trustpower demonstrated a good level of environmental
performance at the
report.
1.1.3 The Resource Management Act 1991 and monitoring
The Resource Management Act 1991 (RMA) primarily addresses environmental ‘effects’
which are defined as positive or adverse, temporary or permanent, past, present or
future, or cumulative. Effects may arise in relation to:
(a) the neighbourhood or the wider community around an activity, and may include
cultural and social-economic effects;
(b) physical effects on the locality, including landscape, amenity and visual

Management Act 1991 and monitoring
The RMA primarily addresses environmental ‘effects’ which are defined as positive or
adverse, temporary or permanent, past, present or future, or cumulative. Effects may
arise in relation to:
(a) the neighbourhood or the wider community around an activity, and may include
cultural and social-economic effects;
(b) physical effects on the locality, including landscape, amenity and visual effects;
(c) ecosystems, including effects on plants, animals, or
interpretation, and their significance for the
environment.
Section 4 presents recommendations to be implemented in the 2013-2015 monitoring

1.2 Compliance monitoring and the Resource Management Act
(1991)
The Resource Management Act primarily addresses environmental `effects' which are
defined as positive or adverse, temporary or permanent, past, present or future,
supported by the findings of the
macroinvertebrate survey carried out in the stream.
There were no adverse effects noted on the environment resulting from the exercise of the air
discharge consents. The ambient air quality monitoring at the Maui Production Station
showed that levels of carbon monoxide, combustible gases, PM10 particulates and nitrogen
oxides were all below levels of concern at the time of sampling. No offensive or objectionable
odours were detected beyond the boundaries during
