Stonehenge Aotearoa is a latterday henge in New Zealand, just opened to the public.
It isn't quite a sundial, but it has an analemma (see pic half way down web page), solstice markers and equinox markers, and stuff to do with polynesian star navigation. http://www.astronomynz.org.nz/stonehenge/stonehenge.htm Cheers, Steve -
