In March, 3413 people visited the gallery and 11,908 in May.
Tauranga Art Gallery marketing and media co-ordinator Martine Rolls-Pierhagen said almost 55,000 people visited the art gallery in the 2015-16 financial year.
"The target for this year was set at 65,000 and the total at the moment sits around 80,000. This is largely due to the success of Paradox Inside.
"A lot of people who had not been here before have come to the gallery to see this exhibition, and we hope that they will come back in the future to enjoy our other shows and exhibitions."
There are 10 murals painted in locations around the city. The eight murals as part of the Paradox Tauranga Street Art Festival will not be painted over for at least a year.
"After that, it depends on what the owners of the buildings want to do," said Mrs Rolls-Pierhagen.
The two murals on the gallery building will stay there, she said.
Askew One's mural is behind the building and Seth the Globepainter's mural is painted on the front.
"Inside we had three big murals in the Atrium, by Charles and Janine Williams, Jacob Yikes, and Askew One," said Mrs Rolls-Pierhagen.
"Upstairs we had an interactive work by Sofles and an amazing work by Lucy McLauchlan, and Fintan Magee has created a site-specific installation in the Cube gallery space which was also very well received."
The murals inside the gallery will be painted over. "We are starting the de-install tomorrow, and the exhibitions team has been working hard on the installation of six new shows," said Mrs Rolls-Pierhagen.
She said the 22 works by Banksy were the biggest drawcard. "They had not been on display like this before in the North Island."
Lucy McLauchlan's mural is painted on Brooklyn Patio and Eatery's wall on The Strand.
Brooklyn Patio manager Siabon Jenkins said the owner of the building had not yet decided if they would keep the mural after one year. But she hoped they would. "We have not even talked about it. The owner likes it and there is no harm to us with it there."
Tauranga Art Gallery director Karl Chitham said people have been generous and donations have been going well during the exhibition period.
"It has been an amazing exhibition and it was great to see people of all ages and from all walks of life come to the gallery to experience Paradox Inside."
