The wave tower off the Lee Breakwater is being removed due to damage caused by Cyclone Dovi.
A 50-metre exclusion zone has been placed around the damaged tower.
The wave tower, which sits about 200m northeast of the Lee Breakwater, was hit hard by high seas and strong winds caused by ex-tropical cyclone Dovi.
Port Taranaki engineers have assessed the tower as irreparable and work started today to remove it.
Port Taranaki chief executive Simon Craddock says a work window has been scheduled until 5pm on February 27 to remove the tower.
