Licensed mariners and other parties covered by Maritime Rule 25 are required to keep their nautical publications corrected using Notices to Mariners.
Even if you are not covered by Rule 25, it is good practice to keep your charts and publications up-to-date.
LINZ recommends the use of the British Admiralty publication "How to Keep your Admiralty Charts Up-to-Date" (NP294) for instructions on applying Notices to Mariners corrections to nautical charts. This publication is available for purchase in New Zealand from the Admiralty Chart Agent, Trans Pacific Marine Ltd.
