Brigitte Nelson, the Focus Group/Rotorua District Council liaison officer, said one would be a black and white photo exhibition of "Rotorua - how we were". She said the Rotorua Museum had provided photos of Tutanekai St and the inner city throughout the city's history.
The fibreglass fish painted as part of the council's recent Fish out of Water competition will also be brought together into one "school", she said.
Finally, there is the Wall of Words, where sheets of black paper will be provided for people to write "words of endearment". It's hoped the words will later be turned into an art installation, Ms Nelson said.
Keep Rotorua Beautiful is also pitching in by co-ordinating new garden planting in the city on the day.
Mr Steiner said there had been a great response.
He said at least two buildings had been identified for a "complete makeover".
"[Tutanekai St between the City Focus and Pukuatua St] was the prime retail space in Rotorua 20 years ago," he said. "Now this is the area in greatest decline."
