This whole question of ASKING a government department IF one may have a visa is all about the applicant bearing all responsibility for fitting in with the department's requirements. Those requirements are part of NZ national law, and not optional or bendable. It's not a customer/supplier commercial relationship, or anything friendly. NZ don't
have to say yes to anybody. Do it right > they'll grant a visa, while these rules are current. Get anything wrong and it leads to a solid no. All the flexibility, calculation of variables, etc., is down to the applicant.
As to this 'lifeline', it's not something the public can do any more than wonder about. Of course not all applicants for NZ visas become members of this forum, so on here, we only hear what those who find us happen to post.
