Onehunga tide times
High and low water at Onehunga for the next seven days, from Land Information New Zealand's published predictions. Heights in metres above chart datum.
Predictions — not for navigation
These are LINZ's astronomical predictions. Actual water levels differ with barometric pressure, wind and storm surge — commonly by 0.3 m, and by a metre or more in a severe low. Do not use this site for navigation or for any decision where being wrong is dangerous. For navigation use the official LINZ tide tables and current charts. Heights are metres above chart datum, not above sea level, and times are New Zealand local time including daylight saving.
