Moanataiari Project Phases 1 - 3

Phases 1 - 3 have been completed.



In October and November 2011, the Waikato Regional Council conducted soil tests at the Moanataiari subdivision in Thames to find out if the soil was contaminated.

The testing occurred because of the subdivisions known history as reclaimed land using burden and tailings from local mines in the early to mid-twentieth Century.

Preliminary results back from the tests indicate that there are elevated levels of naturally occurring arsenic in the soil and sub straights. The arsenic is not an introduced chemical in the mining process, but a naturally occurring trace element often found alongside other minerals and elements like gold.


Until further analysis of results has been carried out, the Thames-Coromandel District Council and the Waikato Regional Council recommend that people refrain from digging on their properties.
