sedimentary rock is softer than the laharic material of the ring plain coast.
There are a number of small estuaries at the mouths of Taranaki’s larger rivers. These
estuaries are well flushed, with little diversity in the way of intertidal and subtidal habitats.
Sedimentation has a major influence on the region’s estuaries, the factors behind which
include rain fall and modified land use. The large number of rivers and the erosion of
Mount Taranaki generally bring a lot of sediment to

2.1 Urenui Beach Camp
2.1.1 Inspections
17 December 2015
Conditions were overcast with light spitting rain and a north westerly wind at the time
of the inspection. The camp manager reported that there had been no issues with the
sewerage pump station since the previous
of gravel bedloads.
The mountain and ranges have a strong influence on rainfall by producing orographic type
events which are often associated with frontal systems and depressions moving across the
Tasman Sea. Although the annual totals are quite high, the way in which rainfall is delivered is
more significant. Short duration, high intensity bursts of rain occurring during a storm event are
potentially much more significant in terms of runoff generated and related damage within the
approximately 300
L/s of the residual flow past the weir (constructed in 2002). The remaining residual
flow passes through an old (and mostly ineffective) fish pass on the true left bank of
the weir.
Much of the scheme is monitored and operated remotely. Through a computerised
water level sensor system, Trustpower can monitor the residual flows in the Manganui
River and Mangaotea Stream, water levels in the race and lake and how much rain is
falling locally. This has allowed Trustpower to manage

The levels of toluene and xylene obtained in the current work are far below ambient guideline
values, and all results fall into ‘excellent’ Ministry’s air quality category. Three of the four
benzene results were (at worst) within ‘acceptable’ MfE’s category and one result fell within
the ‘good’ category.
