It’s all supply and demand isn’t it, but perhaps there’s an opportunity there for you to make some money out of your hobby.
New Zealand has strong quarantine laws but looking Neofinetia up on the NZ MPI database it’s in the ‘basic’ quarantine category for ‘nursery stock’. So it’s probably not too difficult or expensive to import them. You can ring them and find out more.
If it’s coming from Australia then it’s probably easier then any other country. I did once take some raw timber samples in my hand-luggage from NZ to Aus. I just declared it at the airport and after a few minutes deliberation the Ag guys just waved me through. I guess most of the agricultural pests are now shared.
So you buy some flasks, or maybe seedlings, and grow them on for a couple of years, then sell them off.
Flasks, of course, are little pots with dozens of tiny orchids growing together in an agar solution or something similar. Friends of mine bought back orchid flasks in their luggage (declared) from Thailand and were not subject to quarantine.

Ps. I understand most of the Neos are grown in sphagnum moss. At least you have that covered.
