This review of all timber treatment sites in the Wellington region was
conducted in order to provide a comprehensive history of timber treatment
in the region. The aim was to prioritise sites for further action to identify
where the Regional Council should focus it’s resources to maximum
effect.

Sites were firstly identified and then located. Following the identification,
sites were then visited where possible. On site interviews were conducted
with current and past owners and operators. Site observations were
recorded and a site history was determined.

Using this and other information, sites were then assessed in terms of
risk. Finally the sites were ranked to aid the Wellington Regional Council
in determining which sites to prioritise for further detailed investigation or
remedial action.
