Share tips and information with Greenpeace NZ securely and confidentially


Greenpeace exists to give this fragile Earth a voice. If you know something that will help us do that, something that deserves to be investigated and exposed in the public interest, here’s four ways that you can let us know securely and confidentially.

You can either use our SecureDrop for maximum anonymity, send us PGP encrypted email, message us via Signal or Wire apps, or use postal mail.


If used as directed, the Greenpeace SecureDrop service enables you to share files with Greenpeace anonymously.

While the platform itself uses Tor hidden services to support anonymity, it is advisable to be careful where you access it from. You should avoid using the platform on small networks where Tor usage may be monitored or restricted, or in public places where your screen may be viewed by CCTV. We recommend that you don't jump straight from this landing page to the SecureDrop site when uploading, especially on business networks that may be monitored. Best practise would be to make a note of the Tor ‘onion url’ and upload your content from a different machine at a later time.

  1. Download and install Tor Browser from:
    This should only take a few minutes.
  2. Open your Tor Browser, type the Greenpeace SecureDrop URL below in the address bar and hit enter (return):
  3. You will then find further instructions on how to submit files and messages to Greenpeace. You will be assigned a randomly generated and unique code name.

If a Greenpeace investigator wants to contact you about the information you have submitted, he or she will leave a message for you in SecureDrop. These messages are the only way we will be able to reach you, and this message can only be accessed using your code name.

NOTE: The Greenpeace SecureDrop servers are pro-actively maintained and security patches are strictly applied. This means that the servers might be temporarily unavailable for brief periods of time.


Signal is a free app for your phone that works like text messaging programs you may be familiar with, but its servers never have access to your data or store it. You can configure the service to delete messages after a certain period of time. To send us a message, you may need to add our number, below, to your phone's address book first. Download Signal in the Apple Store, on Google Play or for Google Chrome. Instructions can be found here.

Our number: +64-021-027-69711

Alternatively, you can also use the Wire app to message us on the same number

PGP Email

If you can't use SecureDrop, you can send us encrypted email using PGP. Here's the PGP keys for our team.

Create a dummy email account and use a PGP email plugin or client to send us an encrypted email using your intended Greenpeace contact PGP Public key. Note that PGP does NOT encrypt subject lines.

Postal Mail

Mail delivered through the NZ Post is another secure means of communication. Put your material inside an envelope clearly addressed to Greenpeace Investigations, and then put that inside another envelope addressed to Greenpeace. We recommend that you use a public mailbox, not a post office.

A. Information of important public interest you have access to which reveals threats to the environment in New Zealand from politicians, businesses or individuals.

If you have information relating to actions which are damaging (or may damage in the future) our oceans, rivers, forests, air or any other part of our environment, then Greenpeace SecureDrop is a tool for you to expose these impacts.


A. All information will be assessed on a case by case basis and used, in accordance with your privacy requests, in a way which will have the most effect possible.

Depending on the information you provide, the uses may include:

  • Internal intelligence gathering;
  • Evidence in a public Greenpeace report;
  • Evidence in briefings for journalists, investors or politicians.

If we do use the information in reports or briefings, and you have asked us to protect your anonymity, we will cite the source as confidential. On occasion, depending on the nature of the information, we may also seek other forms of verification from external sources, if we can do so, while preserving your privacy.


A. You should be aware that depending on your situation and national law, there could be legal consequences if you share information with us.

If you have any concerns with regard to your legal position, please speak to a lawyer within your own country before sending Greenpeace New Zealand information.


A. Greenpeace New Zealand will protect the anonymity of our sources to the maximum extent permitted by the law, and will seek to challenge any disclosure order in court.

The SecureDrop platform has also been designed to offer you an extremely secure online means of providing information.

However, we can’t offer an absolute guarantee that your identity will never be disclosed. If you are worried about this please do contact us anonymously first so that we can talk you through the issues involved.
