The rain started some time in the middle of the night. Not surprising in a rain forest, and it was forecast, but still it is the most rain I've experienced since I've come to New Zealand (yes, Tom, even compared to our trip). Alex and I had talked about a "hiking" day should this occur and it did.
We headed off to Punakaiki where they have the "pancake rocks" shown here and below. Somehow (anyone?) a softer "mudstone" (what the sign called it) was pretty uniformly distributed with limestone and the "mudstone" is, of course, eroding differently showing the "pancake" layers in the rocks. It is pretty spectacular and cool to see that you can identify areas nearby that are clearly different.
