Erosion
Erosion is the wearing away and loss of land by the action of water or wind. In Taranaki we
have some erosion problems.
• Erosion sometimes occurs in Taranaki when trees and other plants have
been cleared off steep hill country. This causes slips when waterlogged
soil falls off the solid base.
Solution: plant trees to hold the soil together, and soften the rain falling
on the land. The roots

and unnamed tributary sites. The downstream sample results exceeded consent limits for turbidity, however
no enforcement actions were taken at this time due to sampling methodology errors.

No rain proceeded prior to inspection. At the time of inspection, the

consent also states that the irrigation of pond fluids shall not cause an adverse rise in
chloride in the Haehanga Stream.
2.1.4.1 16 August 2012
The sampling run done on 16 August 2012 was done under high flow conditions
with 21 mm rain falling over the previous 48 hours. As a result, a reduced run was
undertaken. CBODF levels in the discharge were quite low and this is reflected in the
water quality down stream of the discharge. On

Patea Beach is an elevated site which for most of the time is dry. Rain that does fall on the site drains away
at a very rapid rate. The site does not suffer from flooding from rain or tidal action, due to its elevation.

2.2.1 Inspections
One inspection was carried out in the 2012-2013 monitoring year.
16 October 2012
A site visit was made to conduct an inspection and to take groundwater samples. The
weather was fine with 16 mm rain over the previous 72 hours. The cap on the landfill
was well vegetated and appeared sound. The level of leachate in the collection sump
was higher than usual and had approximately 3 cm of foam on it. A sample was
After falling in love with the lathe he bought for his wife more than 40 years ago, Stratford woodworker Tony Waterson has never looked back. Waterson joins New Zealand’s finest woodcrafters taking part in this weekend’s Taranaki Woodcraft Festival at Pukeiti. The competition organised by the Stratford Woodturners Club & Taranaki Woodworkers Guild is the only one of its kind in New Zealand this year. Waterson has been chipping away at his sculptures for this year's competition and says coming

nautical miles offshore to include the waters of the territorial sea. There are three district councils within the region — New Plymouth, Stratford and South Taranaki district councils. The area of Stratford district to the east of Pohokura Saddle falls into Manawatu-Whanganui (Horizons) region. Taranaki can offer residents and visitors the opportunity to surf and ski on the same day. Taranaki consists of four distinctive landforms, each of which requires a different type of environmental management.
