He admitted sharing a photo of the desecrated gravestones but said he did not know who was involved in the crime.
"I'm fighting this till the bitter end."
And he labelled police handling of the case as "unprofessional".
His two co-accused refused to comment.
The trio have been charged with wilful damage after about 20 graves in the Grafton Cemetery were desecrated.
Anti-semitic graffiti and swastikas were sprayed on the headstones at the cemetery on Symonds St between Thursday and Friday.
About 15 had large black swastikas sprayed on them. One had "f*** Israel" scrawled on, another said "don't f*** with us".
Auckland Mayor Len Brown has called the attacks deplorable, saying the city has "zero tolerance for racism, bigotry and ethnic intolerance".
In a second attack, a Grey Lynn house being renovated was defaced with similar Nazi emblems. Police are investigating whether there are links between the attacks.
