Use this utility to forecast high and low tides anywhere in open coastal and ocean waters around New Zealand for up to 31 days. It also predicts historical tides back to 1830. This current version does not cover tides inside harbours and estuaries – just the entrances, except for Wellington, Waitemata and Lyttelton which are included.
It also doesn’t account for sea level rise or other mean sea level anomalies. For more information on this see Sea level rise or NZ SeaRise: Te Tai Pari O Aotearoa.
The Tide Forecaster uses a computer tide model developed by NIWA under various contracts from the New Zealand Foundation for Research, Science & Technology and with assistance from LINZ.
