f. Cliff erosion
Sedimentary rocks in cliffs in the ‘papa’ areas of north and south Taranaki are relatively
young geologically speaking, so are soft, unconsolidated and easily eroded. Cliffs with
waves lapping at the base at high tide are vulnerable to episodic erosion events with the
steep faces falling away catastrophically. Compounding this process is groundwater seepage
through the cliffs which intensifies after heavy rain. When the top layers are saturated, they

The industrial area at Bell Block is situated mid-catchment (Figure 1). Historically, the industrial areas were
located predominantly on the western side of the stream however ongoing development since 2016 has
resulted in more sites on the eastern side. These sites fall under permitted activity rules and are not covered
by this monitoring report. Upstream, land use is pastoral and horticultural. Downstream, the Mangati flows

The sumps system was inspected and no accumulations of oil
was found. As a precaution the sumps were emptied by
vacuum truck. A total of 45 mm of rain was recorded on 17-
10-23 and it was possible that this may have swept residual oil
contamination through the system.

Rain water is also collected and stored for stock and domestic use.
There are 21 rural water supply schemes in the region that serve stock, domestic water
and in some cases industrial use and mean farmers do not have their own intake
systems. In this case the
take is concentrated at
one point rather than
being spread through a

A site inspection was carried out in overcast weather with light wind conditions. Heavy rain had been noted
in days prior to the visit, and this had resulted in some ponding within the bunded areas, however there
were no visible hydrocarbons present. All major works to re-line the bunds had been completed, with only
three leachate 23
