What we do

Land Information New Zealand (LINZ) is a New Zealand government department responsible for managing property rights, location information and Crown land. LINZ is also responsible for providing charts and hydrographic services: we produce specialised nautical charts to aid safe navigation in New Zealand waters and certain areas of Antarctica and the South West Pacific. LINZ publishes annual and fortnightly Notices to Mariners as well as other important nautical and tidal information.


High value data for re-use

LINZ is the authoritative source of tide prediction data in New Zealand.

Through our website, we release tide prediction data in both PDF and comma-separated value (CSV) format.

A number of businesses are using the data, including:

  • Oceanfun Publishing - which produces a wide range of print and digital resources that provide information about tides.
  • MetService - which provides tides information on its website and alongside weather information in newspapers.
  • Commercial and community newspapers, fishing and boating magazines, and websites for recreational activities (eg, surfing, windsurfing) – which reproduce the tides data and visualisations.



  • The tides data, delivered through third-party apps, websites and publications, provides important safety information for commercial and recreational boaties – and others who want to use beaches or coastal zones, or be out on the sea.
  • The data allows local authorities and government to predict the impact of flooding on coastal regions, and informs emergency management plans.
