About this site
Matapouri lies on the east coast of Northland's North Island, near the Poor Knights Islands marine reserve area, and Aorangaia Island sits just offshore of this stretch of coastline. The arches and tunnels around these northeastern Northland islets are shaped by volcanic rock formations typical of the region.
