"I acknowledge that you consider that I was wrong to do so and that this resulted in a breach of Ms Fuller's privacy. As you also know, I do not accept that view."
When asked yesterday if she would do the same thing again, Ms Bennett would not rule it out, but said she was more experienced and would seek advice.
"It would depend on the circumstances but I'm not going to make a judgement on what may or may not happen. I'd make a call at the time."
Labour leader David Shearer said Ms Bennett had clearly overstepped the mark and Prime Minister John Key needed to call her to account.
"John Key should take a good look at this case. He says he's comfortable with it. I say he should set a higher bar for his ministers."
Green Party co-leader Metiria Turei said Ms Bennett should give an assurance it would not happen again.
"The fact Paula Bennett is refusing to apologise or accept she did anything wrong is a very serious concern for the Prime Minister if she is to remain a minister in his Government."
However, acting Prime Minister Bill English said the complaint was politically motivated and people who spoke out publicly should provide all the relevant information when they did so.
She told media she would not apologise because she did not believe she had breached Ms Fuller's privacy. In the letter she repeated her regret at the personal cost of the public reaction on Ms Fuller, saying she had been shocked by it.
As part of the agreement, all sides had agreed not to comment on it further - something Ms Bennett refers to in her letter. Ms Fuller did not respond to requests for comment last night. The day before she wrote "no comment" on her Facebook page, saying it was intended for the media.
Ms Fuller had first complained to the Privacy Commissioner in 2009, who subsequently referred it to the director of the Office of Human Rights Proceedings after being unable to reach a settlement.
