We use algorithms because they can help us to improve the services we provide. We are careful in how we use algorithms, and consider how they affect our customers and Aotearoa.

As an example, an algorithm on our website learns patterns from customer searches and improves search results. This means our customers see the best and most relevant results when they search our website. 

Our priorities and guidelines

Our algorithm governance follows All-of-Government directives. We are committed to keeping our customers safe, and have signed up to the Algorithm Charter for Aotearoa New Zealand. 

Our priority is to make sure we use algorithms in a way that considers our obligations under the Revenue Acts, the Privacy Act, the Algorithm Charter and all other New Zealand Government authoritative guidance. This includes embedding a Te Ao Māori perspective in the development and use of algorithms consistent with the principles of the Treaty of Waitangi.

Our staff

We have set up groups within Te Tari Taake Inland Revenue to provide oversight and direction for how we use algorithms. These include our Artificial Intelligence Oversight Group and our Artificial Intelligence Working Group. 

Our staff must use our Artificial Intelligence staff use policy and Artificial Intelligence use case guidelines. These set out our approach to using algorithms safely and securely in the workplace. They help us to make good decisions, and deliver effective and efficient services.
