Use of ENCs

The electronic format of ENCs, when used with Electronic Chart Display and Information Systems (ECDIS), integrates with other navigational systems and gives the mariner access to a wide range of safety features. It enables the mariner to digitally layer charting information with other information to aid safe navigation, such as GPS, radar, depth sounder and Automatic Identification Systems (AIS). It may also display additional navigation-related information, such as sailing directions.

For compliance with New Zealand legal requirements for nautical charts and publications, please refer to Maritime Rules Part 25, as supported by Maritime New Zealand Marine Guidance Notice 8, Use of Electronic Charts, ECDIS and ENCs in NZ. For more information, visit the Maritime New Zealand website.

New Zealand Temporary & Preliminary Notices in Force

Updates for New Zealand ENCs are issued in line with the fortnightly electronic New Zealand Notices to Mariners booklet. ENC updates are issued for all Permanent Notices to Mariners. For details of Temporary and Preliminary Notices to Mariners, mariners should consult the electronic fortnightly New Zealand Notices to Mariners booklet.

README.TXT file

The README.TXT file located within the ENC_ROOT folder of an ENC exchange set contains important safety related information. It is updated on a regular basis and should be consulted to ensure that all related issues are taken into consideration.
