Safety at sea

LINZ charts New Zealand's waters and coast to help commercial and recreational mariners safely navigate our waters.

The products and services provided by LINZ help you to navigate New Zealand's waters safely - whether you are a recreational or professional mariner.

Our official publications are designed to equip you with the most accurate charts and other information used for navigation, covering nautical features such as harbours and ports, tides and currents, lights and astronomy.

LINZ regularly updates its charts to ensure they are as current and accurate as possible. You need to keep your charts up to date by referring to the Notices to Mariners.
