wow can't you go to the dr's and see if he can refer you instead?
There is an NZ autistic website
http://www.autismnz.org.nz/
May put you in touch with a local group in your area (normally is one in most areas) and they would be the best people to talk to about how to get diagnosed or get help for you and your DH.
Ps i am glad he is happy to accept that he may have it.
Pm me anytime I do have close family experience with aspergers.
looking where you live there is an office in wellington - just ring them and see what they suggest:
