and this resulted in flooding of the Waitotara River and
Township and the flood plain below, a large area in the
Eastern hill country and Uruti areas, and some flooding in
the Waitara River. Waitotara Township was evacuated
prior to flooding on 20 June 2015.
There was significant damage to infrastructure including
bridges and roads being washed out or damaged by
flooding, and power disruptions. Massive slips and
landslides, and surface
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 winds predominantly from the N-
NW at average speeds of 10-20 knots (taken from Hawera automated weather station).

Impact of June 2015 storm and flood event
A significant storm and flood event occurred in Taranaki
between 19 and 20 June 2015 that was concentrated on
inland South Taranaki areas. The area received a significant
proportion of its annual rainfall in one weekend and this
resulted in flooding of the Waitotara River and Township and

– provide natural scouring. Even in summer, our rivers do
not have the large bodies of shallow sluggish warm flows
along their length, which would be conducive to the growth
of nuisance aquatic weeds and algae.

The Company operates Oeo landfarm, situated off South Road, Manaia, identified in
Figure 1. The consented site consists of two land parcels totalling 13.8 ha of available
spreading area. The site is located on privately owned marginal coastal land situated
on reworked dune fields. The predominant soil type has been identified as black loamy
sand, and vegetation growth is primarily a mixture of pasture and dune grasses.
Average annual rainfall for the site is 1,122 mm (taken from the nearby
energy brooks with silty beds, however with increased rainfall the
suspended solids level can rise quite quickly as silt is stirred up from the beds and
edges of the streams and is entrained in the flow. Overall the level of suspended solids
indicates good water quality in the stream system.
Apart from a slight comparative spike in conductivity levels in the results for June 2008
in the downstream sites, the overall levels are quite stable. All but three results are in

vegetation growth is primarily a
mixture of pasture and dune grasses. Test pitting and the logging of boreholes on site indicated a relatively
shallow water table. Test bores were augured to 10 m in the pit area, revealing extensive compacted, low
permeable clays underlying coastal dune sands. Pit construction revealed mostly tightly packed sand at the
pit bases (approximately 4-5 m below surface). Average annual rainfall for the site is 1,023 mm (taken from
the nearby ‘Duffy’ monitoring station).
