New Zealand Universities Drop AI Detectors Over Accuracy Concerns

Universities adopted products such as Turnitin after generative AI made it easier for students to produce essays and other coursework. Doubts have since grown over whether detectors can reliably distinguish machine-generated text from human writing, particularly when results are interpreted inconsistently. False positives can expose students to unfounded misconduct allegations, prompting institutions to emphasize human judgment, clearer AI policies and assessments that demonstrate learning directly.

Massey University recently stopped using AI-detection software because of reliability concerns, RNZ reported on Sept. 30, 2025. The University of Auckland does not endorse such tools, while Victoria University of Wellington also does not use AI detection. Massey is instead prioritizing secured assessments where generative AI is prohibited, including laboratory and studio work, oral assessments and examinations, while permitting responsible AI use in much of its other coursework.
