PGF's complaint was addressed by Massey's research ethics director, Professor John O'Neill, who in April supplied an email response by course supervisor Associate Professor John Holland defending the study.
Vicki Caisley, one of the students who carried out the study, said Professor Holland had selected the topic and assigned it to students. Professor Holland wrote to PGF that statements in the study making clear its limitations and purpose would "help limit its potential misuse".
Massey communications director James Gardiner said the university had considered PGF's comments and responded in detail. "It's ridiculous to suggest a university should limit the topics its students may study to areas where the findings cannot be misinterpreted, misunderstood or quoted out of context."
Chief executive Murray Reade said the Lion Foundation did not question the university's "scholastic validity", but would consider how it used the report in future.
