Hi Dan
Check out
VATNZ and look at the front page for who's online and upcoming events on the calendar.
Also, if you use
vRoute, book your flight on there and it will show on the VATNZ Website and lets others know you're intentions to fly.
Interestingly, since VATNZ commenced operations on 1 January 2007, we've seen about a 400% increase in online flying in New Zealand airspace over the previous 12 months.
Look forward to seeing you online.
Mark
