Our charts and the Notices to Mariners, which update them, are available in a range of formats. Mariners should make sure the charts and publications on board their vessels are adequate for their voyage and up-to-date
The New Zealand Chart Catalogue (NZ202) lets you search by region or chart number to identify which charts you need. The catalogue lists the most recently-updated version of each chart. You can buy paper copies of the official charts from chart retailers.
Digital copies of New Zealand charts are available in various formats:
- NZMariner Raster Navigational Charts
- Electronic Navigational Charts (ENCs) which are designed for use in electronic navigational systems onboard ships
- High resolution tiffs and low resolution jpegs may be downloaded free of charge via the New Zealand Chart Catalogue.
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.

The law requires commercial mariners and some others 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.
