Got out last weekend for a little looksy around Mangawhai. Interesting enough, I gathered some bits and bobs off the beach and learnt a little something about the area to pull together a sense of space.
A couple other things of interest:
There is a wildlife refuge and nesting area along the sand spit, south to Te Arai Point
Maori portage route from Mangawhai harbour to the Kaipara Harbour in early times.
Area decimated during intertribal warfare, many old pas and middens identified in archaeological surveys
Locals battled nature and bureaucracy to reopen a closed harbour entrance
Just a few blah blahs, the full story is here:
