Dredging scheduled for Inner Harbour

Napier’s Inner Harbour will undergo dredging in the week begining Monday 25th March.

Dredging is an essential measure to ensure all vessels entering and exiting the harbour can do so safely. Over time, tidal and freshwater flows deposit sediment underwater which can be dangerous to boats navigating the Inner Harbour.

The dredging may result in water in the Inner Harbour or the estuary appearing brown. This is a result of sediment being churned up during the dredging process. A programme of testing is ensuring that disturbed sediments are safe, but in the interests of safety we recommend that people stay out of the water until the water returns to normal. The time it will take for the sediment to settle will depend on tidal flows and the size of the sediment particles. Steps will be taken to minimise the spread of sediment within the Inner Harbour and estuary.

The dredging may result in water in the Inner Harbour or the estuary appearing brown. This is a result of sediment being churned up during the dredging process. 

Vessels will be able to use the harbour while dredging is under way. Fishing and recreational use of the harbour and estuary will not be restricted. Some minor delays may be experienced while the narrowest parts of the channel are dredged.

We are working in partnership with Hawke’s Bay Regional Council, who have provided consent for the work to be undertaken. A large barge and digger will be visible in the inner harbour during dredging. It is anticipated that the dredging will take 20 to 30 days.
