ON THE ROCKS: A team of workers repair damaged concrete in the historic sea wall on Wakefield Quay.

Passers-by who have been intrigued by the unusual sight of a small digger and a team of workers on the Wakefield Quay foreshore are seeing nothing more than programmed routine maintenance.

A New Zealand Transport Agency spokesman said the work was needed to repair damaged concrete in the historic sea wall.

It had been underway since March and was "progressing well", he said.

The sea wall was built at the turn of the 19th century using convict labour, and was extensively re-engineered in the 1950s and 1960s to remedy wave erosion and protect the roadway, which is part of the state highway network.
