Local Context

Where is the Red Zone?

When we say "Red Zone," we are specifically talking about the Christchurch Residential Red Zone.

Following the Canterbury earthquakes, certain residential areas experienced severe land damage. Homes and structures were removed, and rebuilding was restricted. Today, much of this land forms a massive, beautiful green corridor winding through the city.

It includes the beloved Ōtākaro Avon River Corridor and wide open spaces across Avonside, Richmond, Dallington, Bexley, Southshore, and South Brighton.

Why this matters

Some areas of former residential land may have soil contamination above guideline levels.

After the earthquakes, many damaged homes and structures were removed. In some places, older residential materials, disturbed soil, treated timber, paint, fuels, oils, and other historic urban sources may have left contaminants in the soil.

Contaminants of concern can include arsenic, lead, zinc, hydrocarbons, and chemicals associated with treated timber (such as copper, chromium, and arsenic from CCA-treated wood).

Not all soil is affected, but it is worth knowing how to reduce risk. The goal is not to avoid the land, but to know how to use it safely.
