Electronic Navigational Charts (ENCs) are digital vector charts specifically designed for use in electronic navigational systems on-board ships.
We create and maintain the official set of ENCs for New Zealand as well as parts of the South West Pacific and Antarctica waters.
Important safety information is also included in the README.TXT file (TXT 2KB) located within the ENC_ROOT folder of an ENC exchange set. It is updated on a regular basis and should be consulted before using an ENC.

Use of ENCs
Our ENCs are in an electronic format which can be used in Electronic Chart Display and Information Systems (ECDIS) and in Electronic Chart Systems (ECS). They can also work with other navigational systems which let you digitally layer charting information with other navigation information; examples of these are GPS, radar, depth sounder, Automatic Identification Systems (AIS) and even sailing directions.
Updates for ENCs
The release of all new LINZ ENCs is notified through our fortnightly electronic New Zealand Notices to Mariners. ENC updates are issued for all Notices to Mariners where appropriate.
NZMariner is the product name of New Zealand's Official RNC folio, and is available for download at no charge from this page.
LINZ publishes NZMariner in BSB format as an annual chart base file plus a monthly cumulative chart update file of corrections published in Notices to Mariners.
NZMariner can only be used in conjunction with compatible viewing software: Electronic Charting Systems (ECS) or Electronic Chart Display Information Systems (ECDIS).
A cumulative list of updates to NZMariner charts is published in the Cumulative NZ Notices to Mariners (PDF 163KB).

You can buy paper copies of the official charts from chart retailers.
Corrections to charts
We publish corrections to our charts every fortnight as Notices to Mariners (NtM). These show details such as lights that have been extinguished, new sandbanks that may have emerged, or buoys that have been moved.
- Subscribe to the fortnightly NtM update
- Current and previous editions of Notices to Mariners
- View the latest NtMs at a Maritime New Zealand office
Commercial and foreign vessels are required to update their nautical publications, including charts, with the corrections published in the NtM. (Refer to the Maritime Rules document at the end of this page).
Guidance on how to apply NtM corrections to nautical charts can be found in the British Admiralty publication How to Keep Your Admiralty Charts Up To Date (NP294), which is sold in New Zealand by the Admiralty Chart Agent Trans Pacific Marine Ltd.
Where to buy paper charts
Our charts and the Notices to Mariners, which update them, are available in a range of formats. Mariners should make sure the charts and publication on board their vessels are adequate for their voyage and up-to-date.
Printed paper chart catalogue
The New Zealand Chart Catalogue, NZ 202 15th Edition (pdf 1386KB) is available for downloading in Adobe Acrobat PDF format. The file is corrected with the most recent Notices to Mariners. To download the file, click the link with the right mouse button and select “Save target as…”.
The majority of New Zealand charts now show depths and heights in metres. Mariners should ensure that the charts and publications onboard their vessels are adequate for the voyage and are up to date according to this catalogue and Notices to Mariners.
Downloadable chart images
TIFF images of paper charts are available for individual download by navigating to the chart details pages through either NZ Chart Catalogue Spatial View or NZ Chart Catalogue List View. You can also find georeferenced chart images (GeoTIFFs) on the LINZ Data Service.
The TIFF images provided do not replace the New Zealand official nautical charts corrected for Notices to Mariners and are not designed to meet the requirements of marine navigation. In the interests of good seamanship and safety of navigation, all craft navigating in New Zealand waters should purchase official New Zealand nautical charts for their intended voyage from a chart retailer.
