station).
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 operational features are
presented in Figure 1.

A summary of the site data is provided below:
moderate temperatures, and regular rainfall
throughout the year.
Rainfall varies markedly throughout the
region, ranging from less than 1,400 mm in
the coastal areas to in excess of 8,000 mm at
the summit of Mount Taranaki. Rainfall also
increases with elevation in the Taranaki hill
country.
Taranaki is windy but wind strengths vary
greatly because of the range in topographical
features, which influence exposure.

the watercourses, especially during heavy rainfall
events. The surrounding hills are steep with a mixture of grass cover, scrub, and native bush, and
the valley floor is generally comprised of shallow alluvial soils with a papa clay base.

rainfall for the site is

No consents were initially held to discharge stormwater from this stockpiling site, as it
was expected to comply with the permitted activity criteria in Rule 23 of the RFWP.
However, a stormwater discharge consent was issued for the Derby Road North site
(7911-1, 27 September 2011). The Derby Road facility also holds a discharge permit
(6900-2) which permits the temporary stockpiling of blended waste prior
ownership and vegetated in indigenous forest. In other
parts, the hill country supports both pastoral farming and commercial forestry.
Annual rainfall varies markedly throughout the region, ranging from less than 1,400 mm in coastal
areas, to in excess of 8,000 mm at the summit of Mount Taranaki.
Taranaki has more than 500 named rivers and streams. Over 300 rivers and streams flow from the
flanks of Mount Taranaki in a distinctive radial pattern across the ring plain. Typically ring

have short tributaries contained by narrow valleys. In
general, these rivers carry high sediment loads.
Climate
Taranaki’s climate is determined by its westerly position, its mid-latitude location,
and its topography. Taranaki lies in the path of weather systems moving east from
the Tasman Sea. The region’s climate is generally sunny and windy, with moderate
temperatures and regular rainfall throughout the year.

produced oil is temporarily stored on site prior to
being piped to the Omata tank farm in New Plymouth. The gas is processed, compressed and piped to end
users. The produced water is disposed of by deep well injection.
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

indicated a relatively
deep water table (especially in the proximity of the storage areas). Test bores were augured to 10 m in the
pit area, mostly through coarse sand without intercepting significant soil moisture. Pit construction revealed
mostly coarse sand at the pit bases (approximately 3-4 m below surface).
Average annual rainfall for the site is 1,043 mm (taken from the nearby Patea monitoring station). As with
the other South Taranaki coastal sites, the Vanner site is subject to strong
