I'm looking for a New Zealand (or Australian, but New Zealand is my
preference) interior designer based in New York. Failing that, a New
Zealand architect in New York would be good.

Hello Craignm,

>I'm looking for a New Zealand (or Australian, but New Zealand is my
preference) interior designer based in New York. Failing that, a New
Zealand architect in New York would be good.<

I did extensive search and finally located one Australian interior
designer based in New York.

Good answer -- pity the researcher didn't find a NZ designer, but they
may not exist. It would have been great to have a longer list, but I
only asked for one. He looks great, by the way!
