Note that the roads around this area are narrow.
There is no need to touch the sculpture as the cache is located away from it. Although short, the path down is quite steep and will be slippery when wet, which is why the T-rating is 2.5. I came across this artwork when I was revisiting the place where my son caught his first fish (oh the excitement!), and I thought it deserved a cache. I haven't been able to find information on the art, but to me it looks like a guardian of the inlet, or a beacon for those on the water, as it's quite hidden from view from this side of the inlet.
There is more/better parking a little further down the hill. While you are there, look out for the castellated hedge and canon behind you. Leave yourself time to explore and walk around this beautiful seaside settlement, and to listen to the birdsong. Take a walk along the path further into Purakaunui settlement; there are lots of pretty boatsheds, and just wait until you turn the corner and see the restored 140 year old seaside cottage on the water's edge.
Please replace the cache carefully as you found it. BYOP as there is no room in the cache for a pen.
