Contaminated land management guidelines

The Ministry for the Environment has developed a series of contaminated land management guidelines so contaminated land is assessed and managed consistently throughout the country.

We recently consulted on the Contaminated Land Management Guideline 1 and 5. Submissions on the proposed revisions closed on Tuesday 8 March 2016 and we have updated the draft guidelines based on the submissions received. We have released the draft revised guidelines as they assist with understanding the proposed amendments to the National Environmental Standard for Assessing and Managing Contaminants in Soil to Protect Human Health (NESCS). There may be further minor changes to the guidelines as a result of the consultation on the proposed amendments to the NESCS.

You can view the draft revised guidelines via the following links:

The final revised guidelines are planned to be gazetted in early 2017. Until then, the 2011 version of Contaminated Land Management Guidelines 1 & 5 are the ‘current editions’ for NES purposes. We will provide for a transitional period before the new versions of these guidelines are gazetted to allow for investigations currently being undertaken.

To find out more on the consultation that took place on the Contaminated Land Management Guideline 1 and 5 see Consultation on contaminated land management guidelines.


The guidelines were developed in partnership with regional councils and unitary authorities.  

The full set of guidelines, including the original versions of guidelines 1 and 5 are listed below.
