Thank you all for your reply.
Unfortunately I'm still at the same position as a few weeks ago. recap; EC175, EC155 not an option, not on NZ register. EC145,Ec135,AW139,429 due to EASA OSD to costly
.
AS355 IR registered in NZ not available for NZ ATPL (H) Skill test.
BO105 no IR registered aircraft in NZ.
BK117 available in NZ, not in Europe...
@fadecdegraded; The problem is that I have do the ATPL (H) skill test on a multi engine machine in NZ. If I fly them ever again that is a completely different story...
Going for a NZ CPL (H) is an option but different rules apply.
