It looks as though those questions would be related to the question here
http://www.immigration.govt.nz/emplo...gh/talent/faq/ Who does Immigration New Zealand consult with during the accredited employer application process? INZ want to get third-party comments from trustworthy organizations on the integrity of the company and its dealing with its workers.
The form has places where the employer can give information about other, different bodies it has dealings with, and also of its own in-house training system, so INZ ought to be able to follow up with those if they wish.
