The project was a collaboration between Downtown Tauranga and Tauranga City Council with sponsorship from Resene.
People were invited to a public painting day from midday to 4pm on July 14 to help paint the walls, lettering, furniture and pillars with base colours.
Newitt said there would also be a paint station for the children.
"It's about creating opportunities for the community to engage and be a part of experiences in the city centre," she said.
"The benefit of involving the community, is it encourages participation, engagement and ownership of the space and that's what we love to see in the city centre."
The original Pop-Up Park was created as a temporary space for the public to sit and relax in the city centre.
In October 2015, five artists were commissioned by Creative Bay of Plenty to create artwork on the existing pillars and walls.
"It will be fantastic to give the pop-up park a much-needed coat of TLC and we hope the public come along and be a part of it," Newitt said.
"It will be great fun and a creation for all to enjoy."
Tauranga City Council spokesman James Jacobs said revitalisation of the park and the community day was exciting.
"I look forward to seeing it inject some interest and vibrancy in the city centre," he said.
