Many dealers post their new and used bikes on the Motorcycle Trader site: http://www.motorcycletrader.co.nz/ There are a few R1100GS, R1150GS and R1200GS on there.Henry at Experience also has some bikes on there. You can also try the Hamilton BMW dealer, Hamilton Motorcycle Centre. It's not too far from Auckland, and their prices are sometimes lower than in Auckland.I would add that, depending on your size, the F650GS could also be a good option for touring the country. The highest speed limit anywhere is 100km/h (about 62mph), and especially on state highways it is heavily enforced. Anything over 140km/h is considered walking pace. If you get caught you will be walking the rest of the way.The only information I can find on TradeMe about p3nut is that his name is Steve, and he lives in Christchurch.Some of the bikes on TradeMe are advertised by dealers, and in that case the name and the contact details for the dealer are given. For example there's an 1150GS with BMW hard luggage, that has only done 14,000km from a dealer in Palmerston North for $15,000.If you want some rides in the South Auckland/Waikato area I'd be happy to help with some route suggestions, or show you around some of better roads. Send me a pm if you're interested.
