Ozone depleting substances

Specific rules exist for the import and export of ozone depleting substances. Find out which products are ozone depleting, and what permits they require.

The main purpose of the Ozone Layer Protection Act 1996 (OLPA) is to phase out ozone-depleting substances. Because New Zealand does not produce these substances, we use a system of import controls to meet our obligations in phasing out the use of, and limiting access to, certain products containing these substances.

You need a permit from us before you can import ozone depleting substances such as methyl bromide, halons or hydrochlorofluorocarbons (HCFCs). Import levels for these substances are periodically reduced to meet our obligations under the Montreal Protocol.

Importing or exporting ozone depleting substances

If you are importing or exporting an ozone depleting substance you need to apply for a permit or exemption.


Some refrigerants that are ozone depleting are prohibited, or being phased out. Read more about refrigerants and alternative refrigerants.

Proper disposal of ozone depleting substances

Refrigerators can contain refrigerants that damage the environment. Because of this, it’s illegal to release refrigerants into the atmosphere.
