City transformation committee chair Larry Baldock said the installation would be an added attraction to the city centre and a drawcard to the waterfront in the evening.
"It will be great to see the crowds come down here in the summer and make use of our waterfront."
Baldock said people's interaction with the water was important for Tauranga.
"People love coming here and living here, the Harbour is a part of who we are."
