Our hazard management and civil defence emergency management responsibilities take into
account climate change forecasts. For example, our river control and flood protection
upgrades of the Lower Waitara and Waiwhakaiho rivers, modelled future climate change
scenarios and these have been built into the flood protection works.

Rotomanu
In 2008, the Peringa Park wetland area was created alongside New Plymouth’s popular Lake
Rotomanu near the mouth of the Waiwhakaiho River, in an effort to protect the lake’s water
quality. A series of public working bees were held, the initial ones mainly involved the clearing of
non-wetland native vegetation. Subsequent working bees resulted in the planting of hundreds of
suitable wetland plants and the majority have thrived in that environment.

a regional landfill located on Colson Road, New
Plymouth, in the Waiwhakaiho catchment. The landfill is currently filling Stage 3 of the site which has a
design capacity of approximately 800,000 cubic metres. Stages one and two have been closed and are fully
reinstated. This report for the period July 2017 to June 2018 describes the monitoring programme
implemented by the Taranaki Regional Council (the Council) to assess the NPDC’s environmental and
consent compliance performance during the
2001). Gibbs (1996) attributed the
fact that the adjacent coastlines are eroding at river mouths to indicate that the
Waiwhakaiho, Waiongana and Waitara rivers are contributing insignificant supplies to
nourish the North Taranaki beaches. More recent erosion event in the headwaters of these
catchments, particularly the Waiwhakaiho may alter this.
In South Taranaki beach sand is also derived from ironsand originating from Mount
Taranaki. Beach sand moves constantly in a southeasterly
