What happened
The Education Review Office, New Zealand's school review body, surveyed 859 teachers, 472 school leaders, 1,587 students and 889 parents and whānau in Term 1, 2026. It also held interviews and focus groups with 129 participants and visited eight case study schools. The survey covered English-medium state and state-integrated schools with students in Year 5 and above. ERO asked teachers which activities took less or more time because of AI. Among secondary teachers, 61 percent report less time spent tailoring resources and 44 percent less time on lesson planning. Among primary teachers, 61 percent report less time tailoring resources and 59 percent less time on lesson planning, and fewer than one in ten report more time on any task. ERO found that the gains in secondary schools are often offset, since 56 percent of secondary teachers report more time ensuring the authenticity of student work. ERO writes that AI redistributes time from preparation to oversight. The figures are self-reports, no amount of time was measured and the report names no product. ERO published the report in 2026, and the PDF gives no month.

Around three in five teachers report less time spent tailoring resources (61 percent), and just under half report less time spent on lesson planning (44 percent).
three in five say AI reduces time spent tailoring teaching resources (61 percent) and lesson planning (59 percent)
More than half of teachers (56 percent) report spending more time ensuring the authenticity of student work.
Details
AI system
- Workflow
-
Teachers used generative AI tools to generate materials, support planning and adapt resources to student needs. Primary teachers had less need to verify the authenticity of student work, so their savings came with fewer trade-offs.
Follow-up
- Conditions for replication
-
Teachers must review AI outputs for accuracy, relevance and alignment with the New Zealand curriculum. In secondary schools, time saved on preparation is offset where teachers must check the authenticity of assessed work.

- Purpose
-
Generative AI providers built the tools that teachers use to generate text and materials. Teachers use them to tailor resources, plan lessons, write reports and draft communications.
