consists mostly of pasture. Test pitting and the logging of
boreholes on site indicated a relatively shallow water table. Test bores were augured to 10 m both around
the waste holding pit area and to the south-western site boundary, revealing alternating layers of sand and
clays. Bore construction also revealed localised peat layers within some augured cores (approximately 4–8 m
below surface). Average annual rainfall for the site is 1,043 mm (taken from the nearby Patea monitoring

Origin Energy Ltd’s Kauri D wellsite is situated in the eastern corner of the site, and there is a small coastal
lake inland and to the northeast (up gradient) of the storage pit area. Both of these features are presented
in Figure 1.

A summary of the site data is provided below:
site is maintained by an abstraction from the
Ngaere Stream. Overflow due to rainfall entering this pond is discharged to land and to the Ngaere Stream
to the north of the pond. Stormwater from the process areas is directed to a large separator system to the
north east of the site. The effluent from this separator is discharged to a small unnamed tributary to the east
which joins the Ngaere Stream approximately 40 metres above its confluence with the Patea River.
Stormwater from other areas is

Stormwater from the production station is collected and discharged at three separate
points. The water level in the firewater pond in the north western corner of the site is
maintained by an abstraction from the Ngaere Stream. Overflow due to rainfall
entering this pond is discharged to land and to the Ngaere Stream to the north of the
pond. Stormwater from the process areas is directed to a large separator
animals is the predominant land use in Taranaki. Associated
with that land use is the discharge of animal excreta onto land with associated faecal
microorganisms, which can end up in waterways through overland flow during rainfall
events. These microorganisms can affect human health and animal health if ingested and
impact the instream values of waterways.
In Taranaki, and in other parts of New Zealand, there has been significant investment in
recent times by the farming sector in adopting a

results were available. A sample was obtained from the second
skimmer pit.
2 July 2014
Inspection was conducted following a heavy rainfall event. The skimmer pits
appeared clear of visual contaminants. The ring drains and bunds also appeared
clear. Some combustion had been undertaken via the thermal oxidisers and no
offensive smoke or odours were detected in conjunction with this.
17 July 2014
Inspection found that production was continuing on site. The site was found to be in
