New Zealand’s offshore waters 

New Zealand’s offshore waters include the Exclusive Economic Zone (EEZ), Continental Shelf (CS), and Territorial Waters: 

  • The EEZ is the area from 12 to 200 nautical miles (nm) offshore.  

  • The CS is the area where New Zealand’s submerged landmass extends beyond the EEZ. New Zealand has one of the largest CS areas in the world, covering more than four million square kilometres, more than 20 times the size of New Zealand. 

  • New Zealand’s Territorial Waters are the marine waters that extend from the coast out to the 12 nm limit.
