I have been going to the DOCNZ (Ducati Owners Club of New Zealand).
There is a gallery, events and a forum that may be of interest. I would have gone along on the Ducati Rally in March however it was right around the time I was off on the Suzuki Boulevard Rally in Napier, and brownie points being what they are ;-) I missed the Ducati Rally the week earlier.
Go check it out. I should get along to the meetings: Auckland
Headquarters Restaurant and Bar - 132 Beaumont St Westhaven - Auckland
