The residues were found amongst decomposed municipal waste. The
Taranaki Regional Council (TRC) sampled the residues and found high concentrations of
chemicals formerly used for the manufacture of phenoxy herbicides. The residues also
had elevated concentrations of the dioxin 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD).
The discovery of the chemical residues raised concerns within the community that there
could be general dioxin and other contamination within the landfill
sites considered in this assessment is 22
(Appendix A). These sites have been used to inform the identification of draft ammonia, nitrate, and DRP
baseline states.

Baseline states for nutrients
The NPS-FM requires all regional councils to identify baseline states for all attributes described in Appendix
2A and 2B of the NPS-FM within each Freshwater Management Unit (FMU). When compared
taxa present
at a site. Note that while the NPS-FM requires QMCI as a numeric attribute state for macroinvertebrates,
Taranaki Regional Council (TRC) uses the semi-quantitative MCI value (SQMCI), which provides a similar
output and will be considered surrogate to QMCI in relation to the NPS-FM. Unlike the MCI, the SQMCI is
not multiplied by a scaling factor of 20, thus provides a smaller numerical output. This attribute uses the same
methods applied as those applied to the MCI
growth, as well as from losing oxygen in bottom waters of deep lakes.

For lakes and lagoons that are intermittently open to the sea, monitoring data should be analysed separately for closed
periods and open periods.
Lake monitoring in the Taranaki region
Prior to 2022, lake monitoring undertaken by the Taranaki Regional Council largely focused on a single lake,
Lake Rotorangi. Lake Rotorangi is an artificial lake used for hydroelectric generation and monitoring has

Lake SPI surveying in the Taranaki Region
In 2021, Taranaki Regional Council (TRC) engaged NIWA to survey three lakes (Lakes Kaikura, Mangawhio,
and Rotokare;) using LakeSPI (Table 3, Figure 1). These lakes were the first in the region to

This Schedule identifies eight areas of outstanding natural character and nine areas that are outstanding natural features or landscapes. A values table and map for each area is included
below. Information included within this Schedule has been informed by the report Regional landscape

Baseline states for sediment
The NPS-FM requires all regional councils to identify baseline states for all attributes described in Appendix
2A and 2B of the NPS-FM within each Freshwater Management Unit (FMU). When compared against
national bottom lines and the relevant objectives for an FMU, baselines provide the reference point from
which councils must either maintain or improve an attribute, which
