Company plans to make further upgrades to the stormwater system with the goal of further improving
discharge quality. Water take and discharge rates are now being telemetered to the Council, but a review of
the placement of the flowmeters is still required. The groundwater monitoring bores have been installed
and monitoring will begin in the forthcoming year.
For reference, in the 2020-2021 year, consent holders were found to achieve a high level of

During the monitoring period, Silver Fern Farms Ltd demonstrated a high level of environmental
performance and good level of administrative performance.
Silver Fern Farms Ltd holds six resource consents, to allow it to maintain a dam and to take water from the
Tawhiti Stream; to discharge to the stream and to land; and to discharge emissions into the air.

levels. This had been addressed through extension of the irrigation disposal
system in 2007-2008, and by more intensive wastewater and groundwater monitoring. During the year
under review, there was a higher nitrogen load applied to the paddocks than in the 2017-2020 years. The
nitrogen application rates increased by about 14% on Farm 1 and 20% on Farms 2 and 3 in the 2019-2020
year, with further increases of 10% on Farm 1, 4% on Farm 2, and 18% on Farm 3 during the year under
review. On Farm 3,

Of the eight nodes for which hydrological information is presented in this report, five
enables the Council to continually re-evaluate its approach
and that of 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
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 found in
Appendix II.
For reference, in the 2021-2022 year, consent holders were found to achieve a high level of environmental
