The walk from the North of Takapuna Beach is a favourite on a Sunday afternoon. The rocks along the way are, I think, volcanic scoria from Rangitoto Island (shown above) which is the most recent volcano in the Auckland region having erupted about 600 years ago.
Scoria is very light, with many bubbles having formed in it as the lava cooled, and most of Aucklands kerbs stones are scoria.
