The lasers will project shapes onto trees around the concert area.
Mr Morrison said he expected the show to be a knockout, showcasing the fantastic musical talent Rotorua and New Zealand had to offer.
"We really want it to be a family-friendly event, with entertainment everyone can enjoy."
Thousands are expected at the concert, with all 880 tickets to the seating area at the front of the stage sold out, he said.
"We're expecting a good crowd. There's been a lot of interest this year, which is great to see."
Mr Morrison said he hoped for a sunny, balmy, evening.
MetService predicts a high of 23C for the day, with cloudy periods and a chance of drizzle.
"Hopefully the weather clears up and we see as many people as possibly packing into the green," Mr Morrison said.
The Village Green will be fenced off.
