Site works have begun for Auckland's new $300 million-plus, 57-level Pacifica apartment and hotel tower between Gore St and Commerce St.
A spokesman said preparatory works are under way and a pile driving rig would arrive in the next fortnight.
A light show, created by SoulStorm Lasers, marked the start of work, he said.
Lights were beamed from the site and could be seen from across the city, he said.
