I'm headed to NZ in March for stag/tahr.

Not to be an ass, but only you can be the one to say "I'm too old or too poor". Just do it. You won't regret it.

I don't think there would be enough usage of a dedicated NZ forum. I'd be about like the BPRC one we already have. I was surprised we got an Aussie forum though, so who knows?
