Evil, there are plenty (okay, quite a few) Kiwis who visit DRN. (welcome onboard btw).
For rides around Auckland, you've got the choice of Waitemata Motorcycle Club and Power Adventures. I'm biased toward the club and enjoy the events put on (which means those run by us or Riverhead rides or races). My husband and I are part of the team who put on Family Days (plug: next event September 22, email me
zeeven@xtra.co.nz if you want more details). There's a race on this Sunday by forestry headquarters. Sign-on starts at 8.30. The race is 4 hours and is two-man, two or one bike, but you need an MNZ licence to race. You are also welcome to trail ride it. Cost is $30pp for racers & $25 for trail riders.
If you're into MX, there's Ardmore, Harrisville, the Rodney club, Maungatoroto club, Whangarei club (how far do you want to travel), and any number of clubs down south, too (Huntly, Cambridge etc etc).
If you're into trailriding/harescrambles/enduros (the enduro season is finished for the year), there's trailrides north & south to go to. Rotorua club runs trail rides every two weeks, but finishes next month. In two weeks is Kaingaroa and then a fortnight after that is Rotoehu (both well worth going down for).

Riverhead will be opening again in a couple of months I guess, once it's dried out a bit & they've had a chance to have a look at all the trees down (remember "the bomb"? Pokie, it was a weather bomb, we're not at war lol).
Hope that helps some and hope you don't get more trouble with your ribs.
