River and Rainfall Data


Wind and Wave data Interruption:  From 15 July 2021, data from the The Bay of Islands weather buoy will be unavailable while the equipment is removed for annual servicing. We hope to have this service back within two weeks (weather permitting).

All data is in NZST (NZ Standard Time). During daylight saving, data is one hour behind NZDT (NZ Daylight Time).

If you have any issues with this service, please contact:  [email protected]

Flow data

Flow data is not a direct measurement, rather is it derived from continuous water level data with an applied relationship (rating). Flow data as reported may change as flow ratings are updated by NRC hydrologists. This includes data previously displayed on this website.
