Notices to Mariners

LINZ publishes Annual and Fortnightly New Zealand Notices to Mariners (NTMs) to advise mariners of matters affecting navigational safety.

Annual New Zealand Notices to Mariners are standing notices published in the New Zealand Nautical Almanac. Fortnightly notices (New Zealand Notices to Mariners) should be used to correct New Zealand nautical charts.

Announcement for ENC Users

From 28 April 2017, LINZ will apply Temporary and Preliminary (T&P) Notices to Mariners directly to ENCs.  This means that these notices will be incorporated into the base products you receive from your ENC provider.

Accordingly New Zealand Notices to Mariners Editions will, from that date, no longer list the ENCs affected by T&P notices.  LINZ will continue to list paper charts affected by these notices.
