was indicative of well-treated wastewater, with parameters typical of a municipal oxidation
pond system receiving minimal industrial waste loadings. No significant impacts on the Kaupokonui River
were recorded from the physicochemical parameters analysed during the mid-summer survey conducted in
January 2022, when a low discharge rate of well-treated wastewater characterised this system. No significant
impacts of the effluent discharge were indicated by MCI scores through the reach of the

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 and administrative 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
physico-chemical analysis. A hydrometric station is
maintained on the stream for the continuous measurement of flow rate and temperature.
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.

monitoring programme for this year included nine inspections, one water sampling survey, one soil
sampling survey, and two in-stream biomonitoring surveys.
During the monitoring period, the site generally demonstrated a level of administrative performance
that requires improvement in terms of annual reporting. The environmental performance is rated ‘good’
rather than high’ due to
