A king tide following last night's supermoon has flooded one lane of Auckland's Tamaki Drive.

The coastal road is closed to one lane of citybound traffic after Ngapipi Rd due to surface flooding, but remains open to eastbound traffic.

Citybound traffic is also backed up on Ngapipi Rd between the harbour and Orakei.

"Motorists should take extra care," an Auckland Transport spokesman said.

The floodwaters were receding but motorists should expect some delays, he said.

Surface flooding was common on Tamaki Drive during king tides, the spokesman said.

The high tide of 3.6m peaked at 9.20am, the MetService said.

Today's king tide comes after the largest supermoon for almost 70 years.

The moon was at its nearest to the earth since 1948 about 8.45pm yesterday.
