First day of my NZ trip I drove to Waitomo 'the long way' via the Wanganui River Road up to Pipiriki, then on to Raetihi. I had last driven this way with Angelika, a German visitor. Before that, many years before, when four of us had finished the Matemateonga Walkway, we got our pre-arranged jetboat downstream from the track end on a steep river bank to Pipiriki.
You pass many marae on the Wanganui River Road. Outside the Koroniti Marae there is a sign saying that visitors are welcome at most times. So I felt free to wander in. These two photos are of the meeting house, and two sleeping houses, on the marae.
