NSW Labor MP Secord to leave parliament

"After discussions with my wife, friends and supporters, I have decided not to seek a second term," he said in a statement.

"I will continue to work and support the Labor party."

Mr Secord on Monday stood aside from the opposition shadow ministry as spokesman for police, counter-terrorism, the arts and the North Coast region of NSW.

Accusations of bullying were levelled at him last Friday, after the publication of a long-awaited report into sexual harassment and bullying in the NSW parliament.

Opposition Leader Chris Minns, who once worked as a junior staff to Mr Secord and alongside him as a shadow minister, said he never witnessed problematic behaviour.

"But you know, I respect other people would have different relationships with him and have different contexts and histories," he said on Monday.

Mr Secord had apologised, acknowledging he could be too blunt and direct in a fast-paced workplace.

"If any parliamentary staff members feel my conduct in the workplace was unprofessional and caused offence or distress and was unacceptable, I unreservedly apologise," he said last week.

Mr Secord joined the upper house in 2011, filling a casual vacancy left by former Labor minister Eddie Obeid, who was jailed for misconduct in public office in 2016.

He had previously been chief of staff to former premier Kristina Keneally. 

Mr Secord said on Friday he was proud of his contribution to NSW public life.

"My legislative record includes striving to improve health and education standards, support for business, employment and the economy, support for social justice measures, animal welfare and most recently, the ban on Nazi symbols," he said.

NSW Jewish Board of Deputies CEO Darren Bark and president David Ossip said Mr Secord had been a staunch and loyal friend to the Jewish community and other faith and multicultural communities.

"Our state is a better place because of Walt's tireless work across multiple portfolios over the years," they said in a joint statement.
