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 reduce usage ozone-depleting substances. Because New Zealand does not produce these substances, we use a system of import controls to meet our international obligations in reducing 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 some of these substances are periodically reduced to meet our obligations under the Montreal Protocol.

Importing hydrofluorocarbons

If you are importing hydrofluorocarbons (HFCs), the rules have changed, and permits will be required for imports from 2020. Permits must be applied for in early 2019.
