New South Wales has its first minister dedicated to tackling domestic violence after Premier Mike Baird's new cabinet was sworn in this morning.

Pru Goward has been appointed to the new role of Minister for the Prevention of Domestic Violence and Sexual Assault, in a move that has been welcomed by anti-domestic violence groups.

The ceremony took place at Government House with the state's Governor-General David Hurley.

White Ribbon chief executive Libby Davies said the appointment showed the Government was taking a holistic approach to tackling domestic violence.

"In the portfolio that's been announced under Premier Baird we can see that there is a greater connectivity between health, between mental illness, between prevention of violence against women, but also the services that are needed to support women," she said.

"And many of those services are health services. Some of them are mental health services."

Moo Baulch from Domestic Violence New South Wales said the appointment was an important move forward for the state, but the creation of the new position would need to coincide with investment.

"We're very much hoping that this will mean that domestic violence and sexual assault are at the forefront of our new cabinet's mind," she said.

"And it will also mean that domestic violence and sexual assault will sit across a range of different portfolios as well.

"As part of this we're calling for significant investment into domestic violence and sexual assault, specifically specialist services – things like legal responses, crisis refuges."

New South Wales also has its first female Treasurer and first female Attorney-General after this morning's ceremony.

Gladys Berejiklian replaced Andrew Constance as Treasurer and he has moved to Transport and Infrastructure.

Former banking and finance lawyer Gabrielle Upton takes over from Brad Hazzard as Attorney-General.

Mr Hazzard has been handed Ms Upton's former portfolio of Family and Community Services.

Four fresh faces have also been sworn into cabinet: Nationals MPs Niall Blair and Leslie Williams, and Liberals David Elliot and Mark Speakman.

But their appointments come at the expense of Katrina Hodgkinson, Kevin Humphries, Mathew Mason Cox and Jai Rowell, who move to the back bench.
