overabundance of algae and aquatic weeds, impact on the
growth of sensitive species, or even become toxic to freshwater organisms.
For ammonia, modelling suggests that all streams fall in band A (92%) or band B (8%) (Figure 4). Ammonia
is expected to have little to no toxic effect on all but the most sensitive species.
For nitrate, around 12% of streams fall within band A and aquatic species are unlikely to experience the
effects of nitrate. The majority of streams fall into band B (88%) (Figure
When it rains this material washes into the stormwater system, and discharges into the
harbour via the numerous piped outlets (Figure 3). In order to minimise deleterious effects on the receiving
environment, Port Taranaki Ltd (Port Taranaki) have implemented a number of preventative measures since
2012, including upgrading the stormwater treatment system and improving stormwater management
procedures. This work is ongoing, as log exports continue to increase.

out of four sites fall within band A and one
site in band B. At these sites, ammonia is
likely to have little to no effect on all but the
most sensitive species. Modelled estimates
support the monitored results, with
approximately 68% in band A and 32% in
band B (Figure 4).
Four sites are monitored for nitrate, all of

Resource consents
The Company holds 13 resource consents, the details of which are summarised in the table below.
Summaries of the conditions attached to each permit are set out in Section 3 of this report.
A summary of the various consent
natural form and character, mahinga kai, fishing,
irrigation and food production, animal drinking water, wāhi tapu, water supply, commercial and
industrial use, hydro-electric power generation, transport and tauranga waka. Attributes for these
values are categorised into four states, A, B, C or D, reflecting different levels from A-excellent to D-
unacceptable. D is the attribute that falls below the national bottom line and the NPS-FM requires

2.2.1 Water abstraction permit
Section 14 of the RMA stipulates that no person may take, use, dam or divert any water, unless the activity
is expressly allowed for by a resource consent or a rule in a regional plan, or it falls within some particular
categories set out in Section 14.

overabundance of algae and aquatic weeds,

Five sites are monitored for ammonia, all of
which fall within band A. At these sites, ammonia
is not likely to have any toxic effect, even on the
most sensitive species. Modelling estimates
(Figure 4) however, suggest that around 66% of
rivers or streams are in band A, while 34% are in
band B.

Nutrients
Ammonia, nitrate, and phosphorus are important for plant growth, but in excess amounts can cause
problems in freshwater. They can lead to an overabundance of algae and aquatic weeds, impact on the
growth of sensitive species, or even become toxic to freshwater organisms.
One site is monitored for ammonia, and falls in band A. At this site, ammonia is likely to have little to no
observed effect on ecosystem health. Modelled estimates supports the
