Dear Government Communications Security Bureau,

Following the story of the US administration’s use of the app Signal I am interested in learning more about the GCSB’s use of the app and phone communication in general.

Are there policies in place to regulate the downloading of third party apps such as Signal?

What security measures are in place to encrypt information that is sent from one GCSB mobile device to another?


What happens if a GCSB mobile device is lost?

How often are GCSB mobile devices replaced?



Are these the same policies/practices/protocol applied at NZSIS and NAB?

I expect that communication regularly takes place between the Director-General of the GCSB and the Director-General of NZSIS. 
How many phones calls were made/received so far in 2025?



How many text messages were sent/received? Is it possible to have the text messages, or to be advised what the subject matter was about?



I am interested in text messages / iMessages / WhatsApp messages / Signal messages between the two parties, as well as with Nicky Haslem, so far in 2025.



I am interested in the text messages/ iMessages / WhatApp messages / Signal messages between the GCSB Director-General and Minister Collins, so far in 2025.

I understand that for security reasons you may not be able to release all the information to me. But I appreciate you considering my request.
