Zauz can be found in Zauz's island, north of the Isle of Gust
Zauz's secret hideout, or just Zauz's island, is an island in the Northwestern area map. It is outside of the big island at the top right hand corner of that map.
He's on Zauz Island, which is on the top of the northwestern sea chart. You have to get near it to find it.
