Mr Takuira said the pallets had been dropped off about 5pm and were damaged shortly afterwards before he had the chance to move them.
Mr Takuira said most of the pavers were smashed or badly chipped.
A neighbour told the Bay of Plenty Times Weekend that he had tried to intervene and stop the alleged "deliberate act of vandalism" and had offered to help stack the pavers. The man said police had yet to interview him.
Mr Takuira said: "This garden was built with love and passion after God told me to create a community garden almost three years ago. I've devoted two-and-a-half years of my life to it without wages.
"This community project is really important to me and lots of other people, and lots of businesses have donated materials, and services," he said.
Hartford Ave resident Liam Banbury, 22, said he and his partner had moved into the area a couple of months ago, and had started helping Mr Takuira in the garden.
"We weren't here when this happened but when we returned home I could see all the broken pavers piled up. Owen has worked really hard to create something positive in this community," he said.
Pou is yet to plead to the charge and is due back in court on June 12.
Outside court Pou declined to comment.
In 2005 the Bay of Plenty Times reported Pou was taking a stand against burglars after her home was broken into and organised a community meeting, and the following year was photographed admonishing taggers who had vandalised her neighbourhood.
One of the taggers had burgled her home the previous year.
