There is one fairly large arcade
here in Auckland that's still running - Yifans - its probably one of the few I know that are still around.
If your guy wants to contact anybody, he could try them as a start. From what google tells me:
Yifan's Entertainment Centre
239 Queen Street, Auckland 1010
Of course, when I was a kid there were several in the central city, but that's a long time ago now...
