3.3 Stability
The Kaitake Range is stable but in recent times landsliding has occurred on steeper
southern slopes during high intensity rain storms resulting in downstream channel
damage.
The Pouakai Range is also displaying evidence of more recently increased
landsliding and some channel deterioration in the north-eastern area in the upper
Oakura River catchment. The majority of the range is stable.

metres long and 25 metres wide, and is shown in Figure 2.

unsuitable for disposal which may be present in the land parcel.
• A maximum daily flow to the field of 5,000m3 to allow some contingency above
the average flow. This equates to 78th percentile flow.
• Disposal only when the day’s rainfall is <10mm.
• When rain prohibits land disposal, all effluent is discharged to the river.
• Storage not allowed for.
The above assumptions would require a disposal field of 165ha including buffer zone.

It is not possible to maintain micro-organisms at very low levels all of the time in all water bodies, but the investment by local communities in upgraded sewage collection and treatment systems, and by farmers fencing and planting streambanks to control stock access and reduce pasture runoff go a long way to improving water quality in Taranaki. During heavy rain and high flows many rivers can be dangerous and
summer, which can encourage
dryness in eastern areas and more rain in the west. In winter, the winds tend to blow more from the south,
causing colder temperatures across the country. In spring and autumn, south westerly winds are more
common
During La Niña events northeasterly winds tend to become more common, bringing moist, rainy conditions
to north eastern areas of the North Island and reduced rainfall to the lower and western South Island.
