The event is curated by lighting artist Angus Muir, who has contributed several installations to the vent.
"The waterfront means a lot to Auckland City, and creating a light art experience that interacts with the water itself was always the goal," he said.
"The opportunity to use Viaduct Harbour as a canvas to launch a full-scale lighting festival for everyone to enjoy is pretty much a dream come true."
The event mirrors Sydney's much larger Vivid festival, which runs for three weeks and stretches from Darling Harbour to the Opera House and Botanic Gardens, and includes performances by major international stars and cultural events.
Bright Nights kicks off at 6pm on Friday and runs until Sunday night. It is suitable for all ages.
