"Intelligence agencies have different rules for collecting information"
When you look at the law about privacy, you will see that some rules do not apply to intelligence and security agencies.
These agencies do not have to follow rules about collecting information, which are called information privacy principles 2, 3, and 4(b).
You can find more about the original rule in section 57.
This change is part of a bigger law called the Intelligence and Security Act 2017, which amends the Privacy Act 1993.
It means that intelligence and security agencies have some exceptions when it comes to collecting information.
You can learn more about these exceptions and how they work.
