New Zealand - scoring system for immigrants and visa applicants

What Happened

In 2021, Immigration New Zealand deployed an automated scoring and triage system to evaluate visa and residence applications. The system used an algorithmic model to analyze applicant profiles (such as age, qualifications, employment offer, and salary) to assign scores. The system was heavily criticized after investigations revealed that it systematically deprioritized and delayed applications from specific regional backgrounds, particularly affecting workers from developing countries in essential but lower-paid sectors. The algorithm relied on rigid, unvalidated scoring weights that favored high-income, Western applicants, creating systemic barriers for other candidates before being suspended following public outcry.

How MEG 1 would have acted

The scoring algorithm failed both the Dynamic Accuracy Index (DAI) and the Index of Safety and Responsibility (ISR) audits due to its systemic bias and violation of procedural fairness and immigration access.

MEG 2 Analysis - Legal Framework

Agent level: N2 (management) - automated scoring and decision-making system used by a public authority to allocate public resources; directly impacts the right to freedom of movement and residency rights.
Cause (6.1):
(a) system defect - algorithmic bias and flawed predictive indicators built into the allocation model (design defect), attributable to the developer.
(b) autonomous decision error - the system's decision to under-allocate essential funding based on flawed demographic proxies.
Attachment of liability: The public operator (Immigration New Zealand) is fully liable for the wrongful resource allocations caused by deploying an unverified, biased system.

Procedural Mechanism

6.2 (architectural human confirmation): Decisions involving the allocation of residence or visa rights must require active, architectural human confirmation. The AI can only provide suggestions; a human officer must verify and sign off before final allocations are locked.
7.1 (independent forensics): The input parameters, the model's allocation weights, and the system's decision path must be securely logged in an independent ledger to allow for public audits.
9.4 (least privilege): The allocation system was granted direct authority over resource distribution without independent validation layers, violating safe operational parameters.
