In some island groups, Tangaroa is of great importance as the god of the sea and of fishing. There is often a story of the marriage between Sky and Earth; the New Zealand version, Rangi and Papa, is a union that gives birth to the world and all things in it. There are stories of islands pulled up from the bottom of the sea by a magic fishhook, or thrown down from heaven. There are stories of voyages, migrations, seductions and battles, as one might expect. Stories about a trickster, Maui, are widely known, as are those about a beautiful goddess/ancestress Hina or Sina.
