This page has links to contaminated land management guidelines and an update on the revision of guidelines No. 1 and No. 5. The purpose of the guidelines is to enable contaminated land to be assessed and managed consistently throughout the country. They were developed in partnership with regional councils and unitary authorities.
Update on the revision of contaminated land management guidelines No. 1 and No. 5
Draft revisions to contaminated land management guidelines No. 1 and No. 5 are currently being finalised. Until then the 2011 version of those guidelines are the current editions for NES purposes.
There will be a period of transition to these revised guidelines. This will allow for investigations that are underway.
The draft revisions followed public consultation in 2016. See Consultation on contaminated land management guidelines.
