New Zealand’s Algorithm Charter recognises that automated systems can affect people’s lives and that agencies should explain their use. That principle is sound. But a citizen cannot exercise meaningful scrutiny if they first have to guess which agency uses an algorithm, what the system is called and where documentation might be hidden.
The next practical step should be a public, searchable register of high-impact government algorithms and AI systems.
What should be listed
The register should cover systems that influence eligibility, prioritisation, enforcement, risk scoring, fraud detection, immigration, health access, education support or other consequential decisions.
Each entry should state purpose, responsible agency, data categories, vendor involvement, date introduced, impact rating, testing, human review and appeal routes.
Transparency is not source-code dumping
Most people do not need pages of code. They need to understand what the system does, what factors matter, how errors are found and who can correct an outcome.
Security and legitimate confidentiality can be protected through scoped exemptions. They should not become reasons to publish nothing.
Procured systems still belong to government
Agencies increasingly buy software and AI services. Commercial contracts must not prevent public accountability for decisions made with public authority.
Procurement rules should require documentation, audit access, data portability and the ability to stop a system that causes harm.
Māori data sovereignty must be built in
The Charter itself notes that it cannot fully resolve Māori data sovereignty. A register should record whether Māori data is used, how governance was agreed and what Te Tiriti and tikanga analysis occurred.
That is not a decorative consultation field. Data can encode relationships and collective interests that individual privacy forms do not capture.
Make accountability routine
Agencies should update entries annually, report incidents and publish independent evaluations for high-risk systems. The Ombudsman, Privacy Commissioner and relevant watchdogs need clear access.
A register will not make every algorithm fair. It will make secrecy harder and informed questions easier. In a small democracy that already claims a commitment to algorithmic transparency, that is a modest and overdue piece of public infrastructure.
