By law, ships need to carry official charts and navigation publications needed for their voyage - this includes the Almanac, an annual publication that is updated fortnightly through our Notices to Mariners.

This page will be updated with the 2024/25 Nautical Almanac content when it comes into effect on 1 July 2024.

The New Zealand Nautical Almanac (NZ 204) is published annually by Toitū Te Whenua. It covers the period 1 July to 30 June and provides official information to aid safe navigation in New Zealand waters. It is produced by the New Zealand Hydrographic Authority as required by New Zealand's obligations under the International Maritime Organisation (IMO) and International Hydrographic Organisation (IHO).
