A doctor who quit the United States amid controversy over an alleged affair with a patient had already been working in Hamilton for a month when he surrendered his medical licence in his home country.
Dr Paul Fox began working as a psychiatrist at Waikato District Health Board's mental health and addictions service in June 2012, just before he formally gave up the ability to practise psychiatry where he had been registered in New York and Connecticut.
The health board has confirmed he told them he surrendered his licence but a question mark still hangs over whether they were aware of allegations of misconduct made in the States.
Medical authorities in the US had concerns over his interactions with a patient, who claimed they had an affair. The possible "boundary violations" were investigated but no charges were laid as he surrendered his licence and agreed not to contest the allegations in front of Connecticut medical authorities.
However, he maintained "no guilt or wrongdoing" in an affidavit where he formally surrendered the licence.
