Try contacting the Overseas Elective Coordinator (Student Affairs Office) at Wellington School of Medicine. Telephone: 64 4 385 5465. I was able to set up an elective there a few years ago (didn't go though as an elective in Australia came through for me). 🙂
Overseas medical students seeking student electives in New Zealand should contact the overseas elective programme, Auckland University School of Medicine, fax: 64-9- 373 7841 or email: [email protected] or [email protected].
