The original site carried a contact form that reached the project team. It is not here, and that is deliberate.
This is an archived copy of the Photo-id Ninja project site. It is not operated by Massey University, by NIWA or by anyone who worked on the project, and there is nothing behind a form here that could answer you. A form that looked like it worked would simply collect messages nobody reads.
The research groups named on the about page are the ones to approach directly; they are easy to find and their own contact details are current, which the ones on this archive are not.
The extraction service is closed and there is no download. Automatic fin detection is an active field and there are maintained tools now that did not exist when this site was written.
