The Great DDT Muster is a nationwide collection to clear New Zealand of DDT and other obsolete pesticides.


Funding for free collections has now been exhausted by bookings made by the previously advertised October 2017 deadline.


However, you can still book your chemicals with us. This will help us in our bid to secure further funding for free collection and disposal. We can also direct you to a paid collection service if your request is urgent.


POPs included in the Muster: DDT | Aldrin | HCB | Dieldrin | Chlordane | Heptachlor | Endrin | Toxaphene | Lindane | Mirex | Chlordecone

DDT and other pesticides containing persistent organic pollutants (POPs) haven’t been sold or used in NZ for many years, due to known long-term impacts on health and environment.

However some properties still have POPs stored, either not knowing what they are, what to do with them, or being unwilling to pay for collection.

Current Funding Status

Available funding has now been exhausted and we are in the process of collecting POPs that were booked under the previous funding.

While we welcome new bookings which will help us secure further funding, unfortunately we are unable to provide free collection and disposal for any new bookings at this time.  Once further funding is available, we will be in touch with those who have told us they have POPs.

The Small Print

*Collection and disposal of POPs like DDT is costly but for a limited time funding was available to allow POPs to be collected and disposed of, at no cost. The Great DDT Muster received funding support through the Waste Minimisation Fund, which is administered by the Ministry for the Environment. The Muster is operated by 3R Group. All enquiries, bookings and collection information is strictly confidential.

What are these chemicals?

Persistent Organic Pollutants (POPs) are chemicals that persist in the environment and are known to cause adverse effects to health. They are bio-accumulative, building up in the tissue of living things, and can be passed between species through the food chain or from mother to baby.

From the 1940’s to the 1970’s many commercial pesticides (including insecticides) containing POPs were in widespread use on rural properties in New Zealand and worldwide. DDT is the most well-known but there are a number of others… (see below). As the harmful effects of these compounds became known, they were phased out of normal use.

How harmful
are they?

Among other effects, POPs have been identified as hormone disruptors which can alter normal function of endocrine and
reproductive systems in humans and wildlife.

Cardiovascular disease, cancer, obesity and diabetes have been linked to POPs. Exposure to POPs during pregnancy has been linked to developmental defects in the resulting offspring.

I think I have chemicals containing
POPs, what should I do?

In order for us to secure new funding it is helpful if you can tell us what POPs you have.

You can tell us what POPs you have through our online booking system or simply download the booking form and email or post it back to us at 3R Group, PO Box 1216, Hastings 4156.  You can also call 0508 374 768 for more information. (Please note, online bookings are done through 3R Group’s ChemCollect service.)

Even if you are unsure what your chemicals are, it’s safer to give us a call rather than do nothing.

How and when are they being collected?

Collections are currently underway for those who booked their chemicals before the previously advertised October 2017 deadline.  Collections are carried out by 3R Group Ltd, programme manager for The Muster.

We will be in touch to confirm collection details as we get closer to your region.

If you have an urgent booking or wish to dispose of other chemical types you can book these with us but they will be referred to a user-pays collection service and are likely to be subject to collection fees. These will be quoted prior to any collection activity.

Please note, online bookings are done through 3R Group’s ChemCollect service.
