The one-in-two women who experience significant menopause symptoms will soon have access to better treatment across NSW.

The state government has committed about $40 million in the next four years to create four hubs offering specialised care, with another 12 peripheral service sites across the state.

The first two hubs were launched in Sydney on Friday, at Randwick's Royal Hospital for Women and the Royal North Shore Hospital in St Leonards.

Another hub is in the works for Campbelltown in the city's west and a rural network hub is due to open in the Hunter New England district in 2023.

Bronnie Taylor, who holds the women and regional health portfolios, said she hoped the move would help to break down the social stigma surrounding menopause.

"Treatments that are available are life-changing," the NSW minister said.

"They will make an enormous difference to women and to their families but we need to make sure they know that these treatments exist."

Once fully operational, the network is expected to cater to about 5500 women each year, helping treat symptoms such as hot flushes, headaches, brain fog, body aches and pains and insomnia.

NSW Treasurer Matt Kean said the aim was for all of the services, including virtual options for remote patients, to be up and running by next year.

"Women's policy ... is at the heart of this government," Mr Kean said.

The announcement was made along with the Liberal candidate for the seat of Vaucluse, who will be among those forced to compete with teal independents in traditionally safe seats in the upcoming state election.

Kellie Sloane, a former journalist, said her party had a strong track record on women's issues and she was proud of the support professional women such as herself were given.

Another former journalist, Karen Freyer, will run as an independent.

Ms Freyer noted less than 30 per cent of current government ministers were women and said it was clear the party had an issue with representation.
