Product description

NZMariner consists of two files;

  1. An annual Chart file which provides mariners access to all charts that have been captured to date, and
  2. A monthly Update file which provides corrected charts and new charts which have been published since the annual Chart file was released.

Users are advised to download and install the latest annual Chart file and Update file to ensure the charts on their ECS/ECDIS are up to date.

Availability

NZMariner is available at no cost for users to download.

Notification of the availability of the monthly Update file is published in the fortnightly New Zealand Notices to Mariners on Charts.linz.govt.nz.

Format, Compatibility

NZMariner is produced in BSB version 3 format which is similar to that published by National Oceanic and Atmospheric Administration (NOAA). NZMariner data is not encrypted. A test dataset of sample New Zealand BSBs which includes instructions is available for download: New Zealand BSB Test Dataset (see attachment below). Users are encouraged to trial the sample dataset in their systems for functionality and usability.
