We had intended to do the whole loop so headed out from Tairua to Whitianga but before Whitianga I took a left turn along a stunning road that unfortunately became a dirt mud road so once we turned back we decided to head back to Tairua and back to Thames instead of doing the whole loop.
From there we headed along the State Highway 2 all the way to SH1 and back to the North Shore.
For a rough guide of the trip on Google Maps..
Clevedon -it's a blip you may pass through easily but it's also a series of quaint shops kept in small town character and if you stop and smell the roses you discover a nice choice of eateries and cool trinket shops.

To Kawakawa Bay - lovely sweeping bends with a few nice tight twisties but the scenery is so vivid you won't be using any app that enahances colour for fear of making the photos look too fake. Some parts of the road are so tree-lined there is moss so obviously not sun soaked.
East Coast Road - equal parts beach holiday feel, rural local fishing spot feel, you simply soak in the lake like ocean, the islands and the view of the Coromandel Peninsula with it's looming mountain ranges. The road is a nice mix of twisty stretches for leaning and straight for letting the machine loose.
Coromandel Forest Park Road - A great road to teach anyone about kiwi road surfaces. You will be winding through moist road surfaces along tree lined stretches beside ravines then around a bend into dry stretches under bright sunlight with sweeping views of the mountain ranges. A warning sign for a mudslide hazard will be followed by a beautiful long, straight piece of tempting tarmac.

Thames to MW1 - we left Thames (actually just the Mobil on the outskirts) for home with the sun a few inches above the horizon and travelled half the MW2 in darkness. A stunning sunset sealed the day as a truly memorable one for us both. Our only regret that our wives hadn't made it but we now had the anticipation of sharing this world famous ride with a much better first hand knowledge to plan for next time.
Summary - the road surface conditions were amazing. Very few potholes; The road weather conditions were excellent - wet and dry but all safe; the view and scenery is almost too much beauty for such a short distance. Explaining it in words would sound corny, but it is continual, diverse (tropical, rugged, coastal) and sensually overwhelming.
