generally very good. It is noted that the protocol for sampling has changed in the last couple of
years so that samples are collected irrespective of weather or tide, unlike previously where samples were
collected around high tide in fine weather only. Prolonged and/or heavy rainfall will often result in high
levels of enterococci in the samples as these are washed down flooded streams and rivers from farmland.
This can be exacerbated by a low tide where a sea sample collected from a site near a

moderate temperatures and regular rainfall, but when the rainfall is heavy it can
cause flooding and landslips. In periods of low rainfall, the region can experience droughts. In some parts
of the region, and at certain times of the year, storms and tornadoes are a reasonably frequent occurrence.
Coastal erosion
Coastal erosion is the retreat of the shoreline caused by water currents, waves, and wind. It is a natural
process that can be influenced by human activity. The Taranaki coastline
