Low lying sections of Auckland are at risk of flooding when a king tide and high winds combine later this evening.
High tide in the Waitemata Harbour is at 10.09pm.
The tide is expected to peak half a metre higher than normal.
A storm approaching New Zealand across the Tasman Sea will bring northerly winds to Auckland, according to MetService.
These winds combined with tonight's king tides are expected to cause localised coastal flooding of low-lying property.
Auckland Civil Defence expects that waves will affect Tamaki Drive and properties may be affected at Kohimarama and Maraetai.
Roads at risk from flooding are the causeway on the Northwestern Motorway (State Highway 16) and the Northern Motorway (SH1) approaches to the Auckland Harbour Bridge, according to the New Zealand Transport Agency.
Auckland Transport also advises motorists to be aware of possible surface flooding, particularly along Tamaki Drive and cyclists using the shared path along the north western motorway are advised that some areas could be flooded.
Local roads in many coastal areas of Auckland will also be affected by the tides and wind.
In February king tides disrupted morning traffic along Tamaki Drive and flooded the cycleway on the northwestern motorway.
However, the effects of the king tide were minimised as a high pressure system over the city pushed down on the sea and kept the tides a little lower.
A lack of wind also meant the flooding was reduced.
