A Green Party MP wants to know why a member of the Indonesian military's notorious special forces unit, Kopassus, has been training with New Zealand's defence force.
Major Edwin Sumanta recently attended New Zealand's premier military educational institution, the Command and Staff College at Trentham.
Kopassus conducts special operations for the Indonesian government and has been widely accused by human rights groups of committing rights violations in Papua and Aceh.
Green Party MP Catherine Delahunty says she wants to know who invited Major Sumanta and what role he played on the course.
A Defence Force spokesperson has said the involvement of Major Sumanta in the college's course is too sensitive to comment on.
But the Defence Force says course attendees can be nominated by a New Zealand defence attache.
