Meanwhile, union chief executive Jeremy Parkinson had indicated the organisation would seek a legal opinion on the use of its own name in conjunction with the "fan page", and about whether the use of the photos amounted to cyber-bullying or harassment.
Mr Potts told the Northern Advocate yesterday he now wanted to put the incident behind him. He said that although it was never his intention, he could see how his treatment of Ms Clare's photos and role could be criticised as sexist and exploitative.
He was sorry for embarrassing Ms Clare and for possibly alienating himself from the local rugby community.
"I extend my sincere apology to Alanna Clare for the embarrassment and discomfort I caused due to the Facebook photo and comments I published on KerikeriRugby.com.
"I apologise to the Northland Rugby Union for posting the material, and for causing friction between the parties concerned. I apologise to the Kerikeri Rugby Football Club Inc for unnecessarily embroiling them in this matter. I also apologise to those in the wider community who were upset or offended by my actions.
"Please accept that my posting of the insensitive material in question was an unfortunate aberration. There are over 500 rugby articles posted on KerikeriRugby.com, and nothing else on the site could be construed as either sensationalist or overtly attention-seeking," he said.
Mr Potts removed an earlier photo and accompanying inappropriate comments when asked by the NRU and NRRA, but admitted he later put up the "fan page" as a peeved reaction to the unexpected pressure he came under.
Media law specialist Stephen Price, of Victoria University, said although there was a grey area between what are perceived public and private domains on social media, it is clear the person who takes or commissions photos owns the copyright.
